Description

Method and device for distributing transmission resources matched with network service
Technical Field
The invention relates to the technical field of behavior internet, in particular to a method and a device for allocating transmission resources matched with network services.
Background
With the development of internet technology, the types of network services are becoming more and more abundant, and accordingly, different types of network services have individualized demands on transmission resources at the bottom layer of the network when transmitting related data through the internet. The transmission resource may include network bandwidth, transmission path, and routing device, among others. Illustratively, a multimedia service such as video playing needs a larger network bandwidth, an instant messaging service such as WeChat needs a higher network stability, a data access service needs a higher network security, and a common Web access service can meet the requirement of network access.
When a management node of the internet allocates transmission resources for the network service, the network service belongs to an upper layer of the network and is isolated from a bottom layer of the network, the management node allocates the transmission resources of the bottom layer of the network only according to a source address and a destination address of the network service, and any allocation of a transmission path, network bandwidth, routing equipment and the like from the source address to the destination address can be adopted instead of allocating the transmission resources according to the personalized requirements of the network service. Therefore, the personalized requirements of the network service for transmission are difficult to meet, and the providing effect of the network service is affected, and even the network service providing fails.
In order to meet the above personalized requirements, in the related art, when receiving an acquisition request of a Network service for transmission resources, a management node provides a unified global Network resource map to a client corresponding to the Network service by using an SDN (Software Defined Network), where the global Network resource map is used to reflect all transmission resources of the entire underlying Network, such as an entire topology structure and all device information; after receiving the global network resource map, the client corresponding to the network service customizes the transmission resource meeting the self requirement according to the transmission resource reflected by the global network resource map, and then the management node transmits and schedules the related data of the network service according to the customized transmission resource, thereby meeting the individualized requirement of the network service on the transmission resource.
However, in order to make the global network resource map reflect all transmission resources of the entire underlying network, each time an acquisition request is received, the management node needs to acquire information of all transmission resources of the entire underlying network, which easily increases the management cost of the management node for the transmission resources. Therefore, how to reduce the management cost of the management node for the transmission resource while satisfying the personalized requirement of the network service for the transmission resource is an urgent problem to be solved in the transmission resource allocation.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First, a method for allocating transmission resources matching network services according to an embodiment of the present invention will be described.
The method for allocating transmission resources matched with a network service provided in the embodiment of the present invention may be applied to an electronic device capable of serving as a management node of a network, where the electronic device may include a desktop computer, a portable computer, an internet television, an intelligent mobile terminal, a wearable intelligent terminal, a server, and the like.
The network is a communication network for transmitting data of network services, and may include at least a management node for scheduling and managing transmission resources of the network, and a routing device for performing data transmission and processing according to scheduling of the management node. In addition, a client corresponding to a network service may be installed on a device in the communication network, for example, the network service may access a database of the communication network, and the client of the network service may be installed on a management node or a routing device. Or, the client corresponding to the network service may also be installed on an electronic device that is external to the communication network but needs the communication network to perform data transmission, for example, the network service provides a video playing service for a user of the live system, and the client of the video playing service may be installed on a user device of the live system, or may be a server that provides video content in the live system.
As shown in fig. 1, a flow of a method for allocating transmission resources matched with a network service according to an embodiment of the present invention may include:
s101, determining reference information based on a request for acquiring transmission resources by a network service; the reference information is information capable of determining a target transmission resource matched with the network service.
The network service sends a request for acquiring the transmission resource to the management node by a client of the network service. The acquisition request may specifically be a signaling describing service content and related information of a transmission resource, for example, "192.168.0.1 initiates a multimedia export video bandwidth guarantee service, and requests to provide a service point with 100M outgoing bandwidth to support high definition service on demand". It is emphasized that the content of the acquisition request may be varied. Illustratively, the acquisition request may include information characterizing the personalized requirements of the network service for the transmission resources, for example, information of 100Mb bandwidth and transmission destination a; alternatively, the acquisition request may also include information related to the service to be provided by the network service, such as transmitting 100Mb of high definition video to a, acquiring user information in a database, and so on.
Accordingly, the determination manner of the reference information may also be diversified. For example, the information indicating the personalized requirement in the acquisition request may be directly used as reference information, or the acquisition request may be analyzed to extract information in which a target transmission resource matching the network service can be determined, and the extracted information may be used as reference information. For example, if the request content of the acquisition request is "bandwidth 100Mb and transmission destination a", the "bandwidth 100Mb and transmission destination a" may be directly used as the reference information; alternatively, if the request content of the acquisition request is "100 Mb of high-definition video is transmitted to a", the acquisition request is analyzed, and the extracted information "bandwidth 100 Mb" and "destination a" are used as reference information.
The transmission resource is a transmission link, transmission equipment, security performance and the like corresponding to a required bandwidth and a transmission range when transmitting related data of the network service, and a target transmission resource matched with the network service, that is, a transmission resource capable of meeting personalized requirements of the network service, for example, a bandwidth meeting requirements of a video service, a link and transmission equipment meeting requirements of stability of an instant messaging service, and the like.
In addition, in addition to the above information of bandwidth, transmission destination, etc., in order to ensure the security of the transmission resource, the above reference information may also include the security level of the network service, the operation authority of the client corresponding to the network service on the transmission resource, the service content to be provided by the network service, etc., so as to reduce the influence of the abnormal network service on the performance of the network or steal data, etc.
S102, acquiring target bottom layer information matched with the network service based on the reference information; the target underlying information is information for reflecting the target transmission resource.
The target underlying information is used to reflect the target transmission resource, and may specifically include device information, topology information, traffic information, link state information, and the like of the network underlying.
The manner of obtaining the target underlying information may be diversified. For example, the management node may search information corresponding to the reference information from the stored information of the transmission resources of the underlying network as target underlying information. For example, the device information and topology information of the network bottom layer are stored in the management node in advance, the management node monitors the traffic information and link state information of the bottom layer network in real time or periodically, when the reference information is "destination a, bandwidth 100Mb and stable transmission", the device information corresponding to the destination a can be searched from the stored bottom layer information, and the target topology information which can be transmitted from the client corresponding to the network service to the destination a, whose traffic satisfies the available bandwidth 100Mb and whose link state is stable can be searched from the topology information according to the monitored traffic information and link state information.
Or, for example, after determining the reference information, the management node may send a notification for acquiring target underlying information to the underlying network device, so that the underlying network device returns its own device information, traffic information, link state information, and the like; also, the topology information may be updated in real time corresponding to the changing link status and traffic information, and thus, the management node may acquire the latest updated topology information.
S103, distributing target transmission resources for the network service based on the acquired target bottom layer information.
The allocation of the transmission resources may inform the management node of the information of the allocated transmission resources to a client corresponding to the network service, so that the client sends data according to the obtained information; the management node performs scheduling management according to the information of the allocated transmission resources, so that the client corresponding to the network service can perform data transmission by using the allocated transmission resources. In this embodiment, the target underlying information is information for reflecting the target transmission resource, and therefore, the target transmission resource may be allocated to the network service based on the acquired target underlying information.
The manner in which the target transmission resource is allocated may be varied. For example, the target bottom layer information may be sent to a client corresponding to the network service, and the obtained target bottom layer information may be processed into information convenient for use, and the processed target bottom layer information may be sent to the client corresponding to the network service. The information convenient to use may be convenient for transmission, may also be convenient for reading information, and may also be both convenient for transmission and reading, for example, compressing the target bottom layer information to improve the convenience for transmission; or, the target underlying information is drawn into a network resource map including topology structure information, traffic information, and device information, the network resource map is compressed, and the like.
In the scheme provided by the embodiment of the invention, the transmission resource allocation is carried out based on the target bottom layer information for reflecting the information of the target transmission resource, so that the transmission resource allocated to the network service is the target transmission resource matched with the network service, and the individualized requirement of the network service on the transmission resource can be met. Meanwhile, the target underlying information is information for reflecting the target transmission resource, and compared with the traditional global network resource map for directly acquiring all the transmission resources of the whole underlying network, the acquired information is relatively less, so that the management cost of the management node on the transmission resources can be reduced. Therefore, according to the scheme, the effect of reducing the management cost of the management node on the transmission resources can be achieved while the individualized requirement of the network service on the transmission resources is met.
Optionally, the number of the obtaining requests in the embodiment of fig. 1 of the present invention may be multiple;
the acquisition request may include priority information, where the priority information is information representing a processing order of the acquisition request;
step S101 in the embodiment of fig. 1 of the present invention may specifically include:
and for each acquisition request, determining reference information corresponding to the acquisition request according to the priority information corresponding to the acquisition request and the rule of preferentially processing the acquisition request with high priority.
The multiple acquisition requests may be sent by clients corresponding to the same network service, or sent by clients corresponding to respective network services. For the case of multiple acquisition requests, in order to improve the service effect of the network service, the priority of the acquisition requests may be pre-established, so as to determine the reference information according to the priority, and then allocate resources based on the determined reference information. The priority information may be information determined according to a user type of the network service, and illustratively, the administrator has a higher priority than the VIP user, which has a higher priority than the general user. Alternatively, the rule for establishing the priority may be information determined according to the service content to be provided by the network service, for example, the priority of the mail transmission is higher than that of the video playing. Therefore, the information such as the user type and the service content in the acquisition request can be used as the priority information. The priority information may be in the form of information such as "high, medium, and low" or "1, 2, 3".
Illustratively, if the user type in the acquisition request 1 is an ordinary user, and the user type in the acquisition request 2 is an administrator, the priority of the acquisition request 1 is lower than that of the acquisition request 2, the acquisition request 2 is processed first, and then the reference information 2 corresponding to the acquisition request 2 is determined first, and correspondingly, the resource allocation of the network service corresponding to the subsequent acquisition request 2 will also be prior to the resource allocation of the network service corresponding to the acquisition request 1.
Optionally, the reference information in the embodiment of fig. 1 of the present invention at least may include: the transmission range of the data corresponding to the network service and the operation authority of the client corresponding to the network service to the transmission resource;
correspondingly, step S102 in the embodiment of fig. 1 of the present invention may specifically include:
judging whether the operation authority is a configuration authority, if not, acquiring first bottom layer information corresponding to the transmission range, and taking the first bottom layer information as target bottom layer information; the first bottom layer information at least comprises bottom layer equipment information corresponding to the transmission range; if the transmission range is the local range, acquiring second bottom layer information, and taking the second bottom layer information as target bottom layer information; if the local range is not the local range, acquiring third bottom layer information, and taking the third bottom layer information as target bottom layer information;
the second bottom layer information at least comprises flow information corresponding to the configuration authority and local equipment information corresponding to the transmission range; the third bottom layer information at least comprises flow information corresponding to the configuration authority and global equipment information.
The optional embodiment judges the operation authority and the transmission range to acquire the target bottom layer information matched with the operation authority and the transmission range according to different operation authorities and transmission ranges, so that the acquired target bottom layer information can reflect the target transmission resource. Compared with the traditional method of providing a uniform global network resource map for a client corresponding to a network service, the data volume of the acquired information is relatively small, so that the management cost of the management node on the transmission resource is reduced.
For ease of understanding, the above-described alternative embodiments are presented in exemplary descriptive form:
the operating rights may include configuration rights and non-configurable rights. Illustratively, the configuration rights may include: the client corresponding to the network service can configure the transmission resources allocated by the management node based on the self-requirement. For example, the configuration authority of the video playing service is as follows: the client of the video playing service may configure itself, based on the local device information that satisfies the bandwidth requirement and is allocated by the management node, the local device corresponding to the local device information as the transmission path of the routing device according to the transmission policy that the transmission distance is shortest and/or the available bandwidth is the largest, and the like. In addition, for example, the traffic information corresponding to the configuration authority may be a bandwidth allocated to the network service by the management node, and in a specific application, the allocated bandwidth may be the same as or greater than the bandwidth required by the configuration authority. In addition, in an optional implementation manner, if the bandwidth corresponding to the configuration right of the network service exceeds the right to which the service content of the network service belongs, a bandwidth smaller than the requirement of the configuration right may be allocated to the network service.
Exemplary, non-configurable permissions may include: the client corresponding to the network service does not configure the transmission resource allocated by the management node by itself, and directly uses the transmission path allocated by the management node. For example, a client of the web page access service may perform web page access according to a transmission path allocated by the management node, and may not autonomously configure the allocated path.
In addition, the transmission range is a transmission path between the position of the client corresponding to the network service and the transmission destination of the relevant data. For example, the transmission range may be a transmission path between the location of the client corresponding to the network service and the IP address of the data receiving end; or the location of the client corresponding to the network service and the address of an interactive port for interaction between the data receiving end and the network where the management node is located, such as a transmission path between certain websites; the location of the client corresponding to the network service may be a transmission path between a gateway between two networks different from the network where the management node is located, that is, between two external networks; but also a transmission path between the location of the client corresponding to the network service and the physical location of the data receiving end, etc. Any transmission path through which data for implementing a network service is transmitted to a destination may be used as a transmission range of the network service, which is not limited in this embodiment.
For the difference of the operation authority and the limitation of the transmission range, the operation authority can be judged and distinguished in order to obtain the target bottom layer information matched with the operation authority and the transmission range. If the operation right is not the configuration right, that is, the operation right is not the configuration right, it indicates that the client corresponding to the network service does not autonomously configure the allocated transmission resource, and therefore, the management node can obtain the bottom layer device information corresponding to the transmission range. On the contrary, if the operation authority is the configuration authority, the client corresponding to the network service is indicated to autonomously configure the allocated transmission resource, and for the network service with the local transmission range, the management node can acquire the local device information corresponding to the transmission range; for a network service with a global transmission range, the management node may obtain global device information.
It should be noted that the global scope is the whole underlying network, the local scope is a part of the whole underlying network, and if the transmission path corresponding to a certain transmission scope is the whole underlying network, the transmission scope is the global scope; if the transmission path corresponding to a certain transmission range is a part of the whole underlying network, the transmission range is a local range. Correspondingly, the bottom layer device information may include local device information corresponding to the local scope, or global device information. The local device information is the device information of partial devices in the devices of the whole underlying network, and the global device information is the device information of all the devices in the whole underlying network.
In addition, the first bottom layer information may further include link state information, traffic information, and the like, and the second bottom layer information and the third bottom layer information may further include link state information, a topology structure, and the like, so that a transmission resource obtained based on the target bottom layer information may include information capable of improving a resource utilization effect of a client corresponding to the network service. For example, the transmission resources allocated based on the first bottom layer information are two transmission paths, and the link state information and the traffic information of the two transmission paths included in the transmission resources are favorable for the client corresponding to the network service to select the transmission path. Similarly, the link state information and the topology structure included in the second bottom layer information and the third bottom layer information are beneficial to the client corresponding to the network service to determine the transmission path more conforming to the policy adopted by the autonomous configuration, thereby improving the transmission performance.
Illustratively, the operation permission of the web access service is not a configuration permission, and the transmission range is from the position of the client corresponding to the web access service to a certain website address, and then the management node acquires the device information of the local device whose transmission path is from the position of the client to the gateway of the extranet. The operation authority of the multimedia service is a configuration authority, the flow information corresponding to the operation authority is a 100Mb bandwidth, and the transmission range is from the position of the client corresponding to the multimedia service to the gateway of the external network, so that the management node acquires the device information of the local device of which the transmission path is from the position of the client to the gateway of the external network and the available bandwidth is at least 100 Mb. Of course, if the transmission range is from the client corresponding to the network service to each routing device of the network where the management node is located, or the transmission resource allocation can be performed only by using the global device information, the device information of the global device is obtained.
In addition, the acquisition of the traffic information may be various. Illustratively, the management node monitors the traffic information of each device in the underlying network in real time, so that the traffic information corresponding to the configuration authority can be searched from the latest monitored traffic information; or, when there is a demand for acquiring traffic information, the management node sends a traffic information acquisition notification to the bottom layer device corresponding to the transmission range, and then receives traffic information returned by the bottom layer device. For example, the traffic statistic monitoring may be to turn on a traffic monitoring function of a switching device in the underlying network, such as sFlow or Netflow, and periodically sample flow data passing through a port of the switching device, so as to obtain traffic statistic information of each port. The sFlow has a flow monitoring function of providing flow information by adopting a data flow random sampling technology; netflow is a traffic monitoring function that provides traffic information by collecting the number and information of IP packets that enter and leave the network interface.
Moreover, the acquisition of the underlying device information may also be various. For example, the management node may search for device information corresponding to the transmission range from stored global device information of the underlying network; alternatively, for example, after determining the reference information, the management node may send a notification for obtaining the device information to the underlying network devices, such as the switching device and the server, through the multi-type southbound interface, so that the underlying network devices return the device information of the management node. Where a multi-type southbound interface is an interface in a network for interacting with a device, as opposed to a multi-type northbound interface also present in the network for interacting with a user.
Optionally, in an optional embodiment of the present invention, the reference information may further include location information of a client corresponding to the network service;
correspondingly, step S103 of the above alternative embodiment may specifically include the following steps a1 to A3:
a1, if the target bottom layer information is first bottom layer information, determining at least one transmission path information based on the first bottom layer information and the position information by using a preset scheduling algorithm; and distributing the transmission path information to the network service.
The location information is location information of a client corresponding to the network service, and may be, for example, an IP address of a device where the client is located. The first bottom layer information at least includes bottom layer device information corresponding to the transmission range, and correspondingly, the determining manner of the at least one transmission path information may include: according to the address of the bottom layer device in the bottom layer device information and the connection information with other devices in the bottom layer network, a preset scheduling algorithm is used, for example, a scheduling algorithm taking the shortest transmission distance from the position of the client to the position of the bottom layer device and/or the stable link state as the principle is used, so as to determine a transmission path for transmitting at least one piece of data from the client to the bottom layer device, and the rule for routing the data and the device information, etc. related to the transmission path can all belong to the transmission path information. For example, the transmission path information may specifically be a routing table indicating at least one routing manner.
For example, the bottom layer device corresponding to the transmission range is device 3, and the transmission path information includes information corresponding to each of the two transmission paths, including: the transmission path information 1 is that the client sends data to the equipment 1, the equipment 1 sends the data to the equipment 2, and the equipment 2 forwards the data to the equipment 3; the transmission path information 2 is that the client sends data to the device 2, the device 2 sends the data to the device 4, and the device 4 forwards the data to the device 3.
It should be noted that, the allocating transmission path information to the network service may include: the management node sends the transmission path information to a client corresponding to the network service, so that the client sends data according to the received transmission path information, and the management node schedules the transmission resources of the underlying network according to the allocated transmission path information, if the allocated resources are not allocated before the use is finished; relatively free resources continue to be allocated on an allocated basis, and so on.
A2, if the target bottom layer information is second bottom layer information, determining a local network resource map based on the second bottom layer information and the position information; allocating a local network resource map to the network service; and the local network resource map is used for reflecting the local topological resource of the underlying network corresponding to the second underlying information.
The second bottom layer information at least comprises flow information corresponding to the configuration authority and local equipment information corresponding to the transmission range; also, the manner of determining the local network resource map may be varied. For example, local topology information corresponding to the local device information may be searched from the stored global network topology information; drawing a local topological graph according to the searched local topological information; and marking the traffic information of each link forming the local topology structure, such as available bandwidth, the position information of local equipment on the link, such as an IP address, the link state of each link forming the local topology structure and the like in the local topology diagram to obtain a local network resource diagram. The link status may include communication Quality information indicating whether the link is stable, such as transmission rate and QoS (Quality of Service), etc.
Or, for example, similar to the determination method of the local network resource map, in another optional determination method of the local network resource map, the drawing and labeling of the local topology map are the same as the above exemplary method, except that the acquisition method of the local topology information is different, and a topology information acquisition notification may be sent to the local device corresponding to the local device information to acquire the local topology information corresponding to the local device information in real time; and drawing a local topological graph according to the searched local topological information. For the same parts, detailed description is omitted here, and the description of the above exemplary modes is given.
It should be noted that, allocating the local network resource map to the network service may include: the management node sends the local network resource map to a client corresponding to the network service, so that the client autonomously configures transmission resources reflected by the local network resource map according to the received local network resource map and needs of the client, and the management node can receive autonomous configuration information of the client to schedule the transmission resources according to the autonomous configuration information, and if the allocated resources are not allocated before the use is finished; relatively free resources continue to be allocated on an allocated basis, and so on.
A3, if the target bottom layer information is third bottom layer information, determining a global network resource map based on the third bottom layer information and the position information; distributing the global network resource map to the network service; and the global network resource map is used for reflecting the global topological resources of the underlying network corresponding to the third underlying information.
The third bottom layer information at least comprises flow information corresponding to the configuration authority and global equipment information. The global network resource map may be determined in a manner similar to the manner of determining the local network resource map in step a2, or may be determined in various manners. The difference between the two is that the global resource map is a global topology map drawn by using global topology information corresponding to the global device, and information labeled in the global topology map is also related information of the global device. For the same parts, detailed description is omitted here, and the detailed description of step a2 is given above.
It should be noted that, allocating a global network resource map to the network service may include: the management node sends the global network resource map to a client corresponding to the network service, so that the client autonomously configures transmission resources reflected by the global network resource map according to the received global network resource map and self needs, and can receive autonomous configuration information of the client to schedule the transmission resources according to the autonomous configuration information, if the allocated resources are not allocated before the use is finished; relatively free resources continue to be allocated on an allocated basis, and so on.
In addition, in a specific application, because the content of the request for acquiring the transmission resource by the network service is diversified, the reference information determined based on the acquisition request may be inaccurate, so that the target underlying information determined based on the reference information is not accurate enough, and further, the transmission resource allocated to the network service according to the target underlying information may be less matched with the network service.
For this, optionally, the reference information in the embodiment of fig. 1 of the present invention may include transmission performance information;
after step S102 in the embodiment of fig. 1 of the present invention, before step S103, the method for allocating transmission resources matched with a network service in the embodiment of the present invention may further include:
judging whether the data transmission performance of the transmission resource corresponding to the target bottom layer information meets the transmission performance indicated by the transmission performance information;
if yes, executing step S103;
if the information type is not satisfied, acquiring the standby bottom layer information, wherein the information type contained in the standby bottom layer information is larger than the information type contained in the target bottom layer information; and taking the standby bottom layer information as target bottom layer information, and executing and judging whether the data transmission performance of the transmission resource corresponding to the target bottom layer information meets the transmission performance indicated by the transmission performance information.
The transmission performance information may include data transmission performance indexes such as bandwidth, jitter, and time delay, and may specifically be determined by Service content or Quality of Service (Qos) included in the acquisition request, and further carried in the reference information, so as to improve matching degree between the allocated transmission resource and the network Service.
The data transmission performance of the transmission resource corresponding to the target base layer information may be determined in various ways as to whether the transmission performance indicated by the transmission performance information is satisfied. For example, it may be determined whether the data transmission performance of the transmission resource is the same as the transmission performance indicated by the transmission performance information, or it may be determined whether the data transmission performance of the transmission resource is better than the transmission performance indicated by the transmission performance information; and if the same or better, then it is satisfied.
If the transmission performance information does not meet the requirement, the target bottom layer information determined based on the reference information is not accurate enough, so that the matching degree of the transmission resources distributed for the network service according to the target bottom layer information and the network service is reduced, and the transmission performance indicated by the transmission performance information cannot be met. In order to improve the matching degree and meet the requirement of the network service on the transmission performance of the transmission resources as much as possible, the type of the contained information can be acquired, and the standby bottom layer information is larger than the target bottom layer information, so that the accuracy of resource allocation is improved through the relatively richer bottom layer information. Of course, when the acquired backup base layer information is used as the target base layer information, the above-mentioned transmission performance determination is also required.
Illustratively, the transmission performance information of the multimedia service includes a bandwidth of 100Mb and a transmission delay of less than t1 seconds. If the target underlying information is a local network resource map formed by the devices 1 to 3, the data transmission performance of each link of the local transmission resource corresponding to the local network resource map is 100Mb, the transmission delay is t2 seconds, and t2 is greater than t1, and the transmission performance indicated by the transmission performance information is not satisfied. In this regard, the type of information included in the backup base layer information that is larger than the target base layer information may be acquired, for example, the local resource map formed by the device 1 to the device 6 is acquired, the local resource map formed by the device 1 to the device 6 is used as the target base layer information, and the step of determining whether the data transmission performance of the transmission resource corresponding to the target base layer information satisfies the transmission performance indicated by the transmission performance information is executed again. If yes, allocating transmission resources for the multimedia service according to the local resource map formed by the equipment 1 to the equipment 6, otherwise, continuously acquiring the standby bottom layer information of which the information type is larger than that of the local resource map formed by the equipment 1 to the equipment 6. Therefore, the target bottom layer information obtained each time is used for judging the transmission performance, and when the transmission performance is met, the resource is allocated according to the target bottom layer information meeting the transmission performance.
Optionally, the reference information in the optional embodiment may further include a security level of the network service, and an operation right of the client corresponding to the network service to the transmission resource;
before obtaining the standby underlying information, the method for allocating transmission resources matched with the network service according to the embodiment of the present invention may further include:
judging whether the standby bottom layer information belongs to information which can be obtained by the security level and the operation authority;
if so, acquiring the standby bottom layer information.
Because the information that different network services can obtain is different, if a large amount of information of the underlying network is provided for any network service in order to meet performance requirements, part of the network services may obtain information that does not belong to the service operation authority and the security level, and the security risk or the economic loss of the underlying network is increased. For example, the dedicated link is used by an unauthorized network service, and only the administrator can acquire the underlying information to send to the general user, and so on.
In order to solve the above problem, the reference information may further include a security level of the network service and an operation authority of the client corresponding to the network service on the transmission resource, so that before the standby bottom layer information is acquired, it is determined whether the standby bottom layer information belongs to the security level and information that the operation authority can acquire, thereby preventing the network service from acquiring information that does not belong to the service operation authority and the security level.
The operation authority can be represented by information such as user types and business contents of the network services. For example, the user type is a common user, and the user type does not have the right to acquire the standby bottom layer information corresponding to the transmission performance of the VIP user; the service content is access to the database 1, and the service content does not have the right to acquire the corresponding standby bottom layer information of the exclusive link of the important database 2.
The security level may be represented by information such as a user type, a transmission range, and service content of the network service, or may be determined level information such as "high level", "medium level", and "low level" based on information such as the user type, the transmission range, and the service content, and using a preset security level calculation model. In addition, the security level is relatively low, and the standby bottom layer information corresponding to the network service with the higher security level cannot be acquired, for example, the security level of the transfer service is high, the link 1 is used for transmitting data, the security level of the game matching service is medium, and the information of the link 1 cannot be acquired.
Optionally, in another embodiment, if the standby underlying information does not belong to information that can be obtained by the security level and the operation authority of the network service, after the transmission resource of the underlying network is updated, the target underlying information matched with the network service is obtained based on the reference information.
In a specific application, the transmission resource of the underlying network may be updated, for example, after the multimedia service completes video transmission, the transmission resource allocated to the multimedia service is idle, so that the transmission resource of the underlying network is updated, and at this time, the underlying information of the underlying network is also updated accordingly. Therefore, if the transmission resource corresponding to the target underlying information does not meet the transmission performance of the network service, and the standby underlying information does not belong to the information that the security level and the operation authority of the network service can obtain, the target underlying information matched with the network service can be obtained based on the reference information after the transmission resource of the underlying network is updated.
After the transmission resource of the underlying network is updated, the underlying information of the underlying network is also updated, and correspondingly, the obtained target underlying information matched with the network service may also be changed, so that the transmission resource corresponding to the obtained target underlying information at the moment can possibly meet the transmission performance index of the network service.
For example, the transmission performance information of the multimedia service 1 is a bandwidth of 100Mb and a delay of t1 seconds, and the transmission performance information of the multimedia service 2 is a bandwidth of 90Mb and a delay of t1 seconds. When the target base layer information is determined for the multimedia service 2, the multimedia service 1 has already been allocated transmission resources, at this time, the bandwidth of the transmission resource corresponding to the target base layer information 2 that can be allocated and matches with the multimedia service 2 is 89Mb, and the time delay t1 seconds, then the transmission resource corresponding to the target base layer information 2 does not meet the transmission performance requirement of the multi-service 2. Therefore, it is determined whether or not the spare lower layer information "VIP local device information, traffic information, and the like, lower layer information corresponding to a VIP transmission resource" belongs to information that can be acquired by the security level and the operation authority of the multimedia service 2. And therefore, after the transmission resource of the underlying network is updated, for example, after the multimedia service 1 completes video transmission, the target underlying information matched with the multimedia service 2 can be acquired based on the reference information corresponding to the multimedia service 2. At this time, it is highly possible to allocate the transmission resource with a delay of t1 seconds to the multimedia service 2 while the transmission performance previously allocated to the multimedia service 1 satisfies the bandwidth of 100Mb, thereby improving the matching degree between the multimedia service 2 and the transmission resource.
As shown in fig. 2, a flow of a method for allocating transmission resources matched with a network service according to another embodiment of the present invention may include:
s201, analyzing the request for acquiring the transmission resource by the network service, and obtaining the transmission range of the data corresponding to the network service and the position information of the client corresponding to the network service, which are included in the request for acquiring.
The transmission range corresponding to the network service may reflect the security of the network service, so that the transmission ranges in steps S202 to S203 are used to determine the security level of the network service, for example, the transmission range of the data corresponding to the database access service is an underlying network, which reflects that the service is relatively safe, and the transmission range of the data corresponding to the multimedia service is from the location of the data to an external network gateway, which reflects that the service is relatively safe. In addition, the location information of the client may be used to look up registration data for the network service, which is then used to obtain the security level.
S202, obtaining the user type corresponding to the network service from the registration data corresponding to the position information.
The location information of the client corresponding to the network service may be an IP address of the client or a geographic location of the client. The user type corresponding to the network service may be acquired in various manners. For example, the method may send an acquisition request of registration data to an IP address of the client, and further receive a user type corresponding to the network service, which is searched and returned from the registration data of the device where the client is located, or from a registration database of the device where the client is located. For example, the user type corresponding to the network service may also be searched from the registration data according to a corresponding relationship between the geographic location of the client corresponding to the network service and the registration data.
It should be noted that, in the correspondence between the geographic location of the client corresponding to the network service and the registration data, the geographic location of the client corresponding to the network service plays a role as the client identifier corresponding to the network service. In addition, for the case that the location information of the client is the IP address of the client, the user type may be obtained by searching the user type corresponding to the network service from the registration data according to the correspondence between the IP address of the client corresponding to the network service and the registration data. At this time, the IP address of the client corresponding to the network service functions as a client identifier corresponding to the network service, similarly to the above-described geographical location.
Illustratively, the user types may specifically include an administrator, a super user, a general user, and the like.
And S203, based on the user type and the transmission range, obtaining the security level of the network service by using a preset security level calculation model.
In an alternative embodiment, the obtaining of the security level of the network service may include: and searching the security level corresponding to at least the user type and the transmission range as the security level of the network service according to the corresponding relationship between the pre-stored characteristic information of the network service and the security level at least based on the user type and the transmission range. It should be noted that the user type and the transmission range both belong to the characteristic information of the network service.
Illustratively, the user type is a normal user, and the transmission range is transmission to an external network gateway, and the corresponding security level is "low"; the user type is a VIP user, the transmission range is from transmission to an external network gateway, and the corresponding security level is a middle level; the user type is administrator, the transmission range is to be transmitted to a certain device of the underlying network, and the corresponding security level is "high level".
In another alternative embodiment, in order to improve the accuracy of the security level determination, obtaining the security level of the network service by using a preset security level calculation model based on the user type and the transmission range may include:
acquiring first weights corresponding to two information types of a user type and a transmission range from prestored information type weights;
acquiring a second weight corresponding to the respective content of the user type and the transmission range from prestored category content weights;
calculating formula S ═ w by using the first weight, the second weight and the safety factor1×wu[i]+w2×wr[j]Calculating to obtain the safety coefficient of the network service;
wherein, w1A first weight, w, corresponding to the information type of the user type2For transmitting range informationFirst weight, w, corresponding to the categoryu[i]A second weight, w, corresponding to the content i of the user typer[j]The second weight corresponding to the transmission range j, and S is a safety coefficient of the network service;
and determining the security level corresponding to the calculated security coefficient from the corresponding relation between the preset security level and the security coefficient, and taking the security level as the security level corresponding to the network service.
Since the user type and the transmission range respectively reflect different security degrees, different first weights can be set for different kinds of information reflecting security. For example, the first weight of the user type may be set to be smaller than that of the transmission range: w is a1<w2. On the basis, the safety degree reflected by different information contents is different for each kind of information, so different second weights can be set for different contents in the same kind. Illustratively, a second weight of the administrator may be set>Second weight of VIP user>The second weight of the common user is transmitted to the second weight of the underlying network>The second weight transmitted to the extranet gateway, i.e. the second weight of the specific information content in the various kinds of information reflecting security, may decrease with the increase of the index depth, such as with the decrease of the arithmetic difference. Of course, in various types of information reflecting security, the second weight of specific information content may also be increased progressively with the increase of the index depth, and the specific setting may be performed according to the specific situation of the information capable of reflecting security, which is all reasonable.
And the safety factor of the network service S can be positively correlated with the safety level, and the larger the value of S is, the higher the safety level of the network service is. Alternatively, the magnitude of the security factor of S as the network service may be inversely related to the level of the security level, and the larger the value of S, the lower the security level of the network service. The specific correlation may be determined according to a specific weight setting, which is reasonable, and this embodiment is not limited thereto.
In addition, the security level corresponding to the calculated security factor is determined from the preset corresponding relationship between the security level and the security factor, and specifically, the security level corresponding to the calculated security factor may be searched in the preset corresponding relationship between the security level and the security factor.
Illustratively, a first weight w of a user type information category is set11, the first weight w of the information category of the transmission range22. In the content of the user type, the second weight w of the administratoru[1]3, second weight w of VIP useru[2]2, second weight w of the common useru[3]1. In the content of the transmission range, the second weight w transmitted to the underlying networkr[1]2, second weight w transmitted to external network gatewayr[2]＝1。
Calculating formula S ═ w according to the safety factor1×wu[i]+w2×wr[j]The safety factor is 1,8]Therefore, the corresponding relationship between the safety factor and the safety level can be divided into three basic levels, which are specifically shown in the following table 1:
Figure BDA0001951622820000181
if the information for reflecting the security of a certain multimedia service includes that the content of the user type is a VIP user and the content of the transmission range is transmitted to the extranet gateway, the security factor of the multimedia service is S1 × 2+2 × 1S 4 ∈ [4,6] according to the above security factor calculation formula, and the security level of the multimedia service is a medium level.
It should be noted that the setting of the weight, the correspondence between the security level and the security factor, and the division of the security level are only exemplary, and in a specific application, the security level may be divided according to the setting of the weight and the division requirement. For example, in order to make the security level more accurate, the classification may be more than three levels, such as on the basis of the existing three levels, each level is classified into 3 levels, resulting in nine levels, and so on.
In addition, in the above determining manner for calculating the security factor, in addition to the user category and the transmission distance, the data type of the data to be transmitted, the service type to be provided by the network service, and other information capable of reflecting the security of the network service may be used for calculation. For example, the data type "compressed package" of the data to be transmitted reflects lower security than the data type "text", the data type "compressed package" reflects higher security than the data type "hyperlink", and so on. The service type "access database" to be provided by the network service reflects lower security than the service type "transmit video", etc. Correspondingly, a first weight w of the information category "data type of data to be transmitted" may be set3And a first weight w of "traffic type4(ii) a The specific content k of the data type, such as "text", "hyperlink", etc., has a second weight wc[k]And a second weight w of a specific content m of "type of service", such as "transmitting video", "accessing data available", etcb[m](ii) a And obtaining the formula S ═ w for calculating the security level1×wu[i]+w2×wr[j]+w3×wc[k]+w4×wb[m]。
It is emphasized that the safety factor calculation formula may include: calculating the product of a first weight of each information category and a second weight of specific content of the information category aiming at each category of information capable of reflecting the security of the network service; and adding all the obtained products to obtain the safety factor. Any information that can reflect the security of the network service may be used as the information for determining the security factor in the present invention, which is not limited in this embodiment. Accordingly, the operation term in the safety factor calculation formula may not be limited to two or four terms in the above example.
S204, detecting whether the network service is abnormal or not by using a preset security algorithm corresponding to the security level; if not, executing step S206 to step S208; otherwise, step S205 is executed.
The preset security algorithms corresponding to different security levels are different in complexity, the network service with the high security level corresponds to the security detection algorithm with the low complexity, the efficiency is improved, the network service with the low security level corresponds to the security detection algorithm with the high complexity, the missing detection is reduced, and the security is guaranteed. Compared with the adoption of a unified safety detection algorithm, the efficiency and the safety of safety detection can be considered at the same time.
For example, whether a high-level network service is abnormal or not can be detected by using a key feature comparison mode, for example, whether the location information of a client corresponding to the network service is the same as the pre-stored location information or not, whether the user information and the timestamp carried by the acquisition request meet a preset safety condition or not, and the like; whether the network service of the middle level is abnormal or not can be detected by utilizing a flow detection algorithm; a traffic filtering algorithm may be used to detect if a low level network service is anomalous.
And S205, outputting prompt information indicating the network service abnormity.
When the detection result is abnormal, it indicates that the network service is most likely to have negative effects on the security of the underlying network, such as attacking the underlying network, stealing information, and the like. Accordingly, a prompt indicating a network service anomaly may be output. Of course, the prompt message may be output to the operation and maintenance personnel of the network, or may be displayed on the display device.
It should be noted that, in order to ensure security, after the prompt message of the network service abnormality is output, the allocation flow of the transmission resource may be ended. In addition, in order to cope with the possible false detection, after the prompt message of the network service abnormality is output, a notification for confirming whether the network service is abnormal may be received, and if the notification indicates that there is no abnormality, steps S206 to S208 may be performed. The notification for confirming whether the network service is abnormal may be confirmation information input by operation and maintenance personnel, or a recheck result obtained after rechecking by using a standby security detection algorithm. The complexity of the standby safety detection algorithm is higher than that of the safety detection algorithm for acquiring the detection result corresponding to the abnormal prompt information.
S206, determining reference information based on the request for acquiring the transmission resources by the network service; the reference information is information capable of determining a target transmission resource matched with the network service.
S207, acquiring target bottom layer information matched with the network service based on the reference information; the target underlying information is information for reflecting the target transmission resource.
And S208, distributing target transmission resources for the network service based on the acquired target bottom layer information.
S206 to S208 are similar to S101 to S103 in the embodiment of fig. 1, except that in the information obtained by analyzing the obtaining request in step S201, step S206 may use information that can determine the target transmission resource matching the network service to construct the reference information. For example, the extracted information for constructing the reference information, such as the transmission range, the location information of the client corresponding to the network device, the bandwidth, and the transmission performance information, may be encapsulated as a message. For the same parts, detailed description is omitted here, and the detailed description is given in the above description of the embodiment of fig. 1 of the present invention.
It should be noted that, in an optional implementation manner, if the security level determined in this embodiment needs to be used in the subsequent step of allocating transmission resources, in step S206, the security level determined in step S203 may also be encapsulated in the above message.
Compared with the embodiment of the invention shown in fig. 1, the embodiment shown in fig. 2 evaluates and detects the security level of the network service, and does not allocate network resources to the abnormal network service, so as to solve the security problems that the abnormal network service may maliciously attack the underlying network and steal data, and improve the security of the network.
And for network services with different security levels, a security detection algorithm which is suitable for the security level is selected in a targeted manner, a security detection algorithm with low complexity is selected for a network service with high security level, the efficiency is improved, a security detection algorithm with high complexity is selected for a network service with low security level, the missing detection is reduced, and the security is guaranteed. Compared with the adoption of a unified safety detection algorithm, the efficiency and the safety of safety detection can be considered at the same time.
Optionally, after passing the security detection, to avoid that the transmission resource acquired by the network service request exceeds the acquisition permission of the service, and to ensure that data transmission of the service can be performed, the acquisition request in the embodiment of fig. 2 of the present invention may further include service content to be provided by the network service; for subsequently acquiring the operation right corresponding to the service content, and further allocating the transmission resource.
Correspondingly, before step S206 in the embodiment of fig. 1 of the present invention, the data transmission method matched with the network service in the embodiment of the present invention may further include:
acquiring an operation authority corresponding to the network service from the registration data corresponding to the position information; the operation authority is the operation authority of a client corresponding to the network service to the transmission resource;
judging whether the information of the transmission resource corresponding to the service content belongs to the information which can be obtained by the operation authority;
and if not, changing the operation authority contained in the acquisition request into the operation authority corresponding to the service content.
The obtaining mode of the operation authority may be various, for example, when the registration data includes information about the operation authority, the operation authority corresponding to the network service may be extracted from the registration data corresponding to the location information; or, when the user type is included in the registration data, the operation authority corresponding to the user type in the registration data may be determined according to the corresponding relationship between the user type and the operation authority. It should be noted that, because the location information is location information of the client corresponding to the network service, the registration data corresponding to the location information corresponds to the network service, and correspondingly, the user type or the operation authority included in the registration data corresponds to the network service.
In addition, the judgment of whether the information of the transmission resource corresponding to the service content is unauthorized, that is, whether the information belongs to the information that can be acquired by the operation authority, may also be various.
Illustratively, if the service content includes the operation right, it may be directly determined whether the operation right exceeds the operation right corresponding to the network service acquired from the registration data corresponding to the location information; if not, it belongs to, otherwise, it does not belong to. For example, from the registration data corresponding to the location information, the operation right corresponding to the acquired network service is "right to read transmission resource", the service content is "read path information, and the website is accessed according to the transmission path corresponding to the path information", the operation right "read" in the service content does not exceed the operation right corresponding to the network service in the registration data, and the information "path information" of the transmission resource corresponding to the service content belongs to the information that the operation right can acquire. If the service content is 'configure bandwidth to transmit 100Mb of video', the operation authority 'configuration' in the service content exceeds the operation authority 'reading' corresponding to the network service in the registered data, and the 'topology map corresponding to 100Mb bandwidth' of the information of the transmission resource corresponding to the service content does not belong to the information which can be acquired by the operation authority.
Or, for example, if the service content does not include the operation right, it may be determined whether the operation right corresponding to the service content exceeds the operation right corresponding to the registration data according to the correspondence between the service content and the operation right. For example, the operation right corresponding to the service content "transmit 100Mb video" is "configuration or write operation", and the operation right corresponding to the service content "access web page" is "read". If the operation authority corresponding to the service content exceeds the operation authority corresponding to the registration data, the information of the transmission resource corresponding to the service content does not belong to the information which can be acquired by the operation authority; if not, the information of the transmission resource corresponding to the service content belongs to the information which can be obtained by the operation authority.
In addition, in order to ensure that the unauthorized network service can perform data transmission, the operation authority contained in the acquisition request can be changed into the operation authority corresponding to the service content; and then determining reference information based on the acquisition request with the changed operation authority so as to allocate subsequent transmission resources based on the reference information. For example, for video transmission without configured authority, transmission path information of the video may be allocated to the video transmission, but a topology resource corresponding to the requested bandwidth, such as a global or local network resource map, is not provided.
Corresponding to the above method embodiment, an embodiment of the present invention further provides an apparatus for allocating transmission resources matched with a network service.
As shown in fig. 3, the structure of the apparatus for allocating transmission resources matched with a network service according to an embodiment of the present invention is applied to a management node, and the apparatus may include:
a reference information determining module 301, configured to determine reference information based on a request for acquiring transmission resources by a network service; wherein the reference information is used for determining a target transmission resource matched with the network service;

a resource matching module 303, configured to allocate the target transmission resource for the network service based on the obtained target bottom layer information.
In the scheme provided by the embodiment of the invention, the transmission resource allocation is carried out based on the target bottom layer information for reflecting the information of the target transmission resource, so that the transmission resource allocated to the network service is the target transmission resource matched with the network service, and the individualized requirement of the network service on the transmission resource can be met. Meanwhile, the target underlying information is information for reflecting the target transmission resource, and compared with the traditional global network resource map for directly acquiring all the transmission resources of the whole underlying network, the acquired information is relatively less, so that the management cost of the management node on the transmission resources can be reduced. Therefore, according to the scheme, the effect of reducing the management cost of the management node on the transmission resources can be achieved while the individualized requirement of the network service on the transmission resources is met.

the second bottom layer information at least comprises flow information corresponding to the configuration authority and local equipment information corresponding to the transmission range; the third bottom layer information at least comprises flow information and global equipment information corresponding to the configuration authority.
Optionally, the reference information in the embodiment of fig. 3 of the present invention further includes location information of a client corresponding to the network service;
the resource matching module 303 is specifically configured to:
