A method for adjusting an operation state of a service management system according to an exemplary embodiment of the present application will be described with reference to the accompanying drawings.

In some embodiments, as shown in fig. 1, a method for adjusting an operation state of a service management system includes:

step 101: and determining the neighbor topological relation among different terminal devices.

In specific implementation, the service management system includes several management subsystems and an upper controller, the upper controller performs instruction interaction with each management subsystem, each management subsystem includes a terminal device and a Software defined packet transport network (SPTN) device, and communication connection can be established between each management subsystem based on the corresponding SPTN device.

The SPTN technology can provide network slicing capability and support differentiated service requirements of different service scenes, such as 5G, special lines of government enterprises, cloud computing and the like. The SPTN technology can provide intelligent and automatic management and optimization of the service, realize visual management of service quality, automatically adjust and optimize service paths, and build intelligent deployment and intelligent operation and maintenance capabilities of the service. The SPTN technology can provide the advantage of network programmability, and a user can dynamically adjust the network according to the application of the user through the self application program and through the communication of the super service user of the SPTN.

The neighbor topology between different terminal devices requires the use of neighbor discovery protocol (Neighbor Discovery Protocol, NDP), which is an important underlying protocol in the internet protocol version6 (Internet Protocol version, IPv 6) protocol system. The internet control message protocol version6 (Internet Control Message Protocol Version, icmpv 6) message can implement stateless automatic configuration: router discovery, prefix discovery, parameter discovery, repeated address detection; address resolution, neighbor unreachable detection, router redirection, etc. ICMPv6 is one of the underlying protocols of IPv 6. The protocol type number (value of Next Header field in IPv6 message) of ICMPv6 is 58. The message format of ICMPv6 is shown in fig. 2. Wherein, the Type indicates the Type of the message, 0 to 127 indicates the error message Type, and 128 to 255 indicates the message Type; code represents the type of subdivision of this message type; checksum represents the Checksum of the ICMPv6 message, and the checked part comprises ICMPv6 data and the header part of IPv 6; data: ICMPv6 data.

There are 5 message types in the ICMPv6 message defined for supporting NDP, type133, type134, type135, type136 and Type137. Wherein, type133 is a router solicitation (Router Solicitation, RS) message, type134 is a router advertisement (Router Advertisement, RA) message, type135 is a neighbor solicitation (Neighbor Solicitation, NS) message, type136 is a neighbor advertisement (Neighbor Adivertisment, NA) message; type137 Redirect (Redirect) message. Therefore, the NDP message includes a RA message, a RS message, a NA message, a NS message, and a redirect message. The Code field value of the NS message is 0, and functions in address resolution are to obtain the link layer address of the neighbor, verify whether the neighbor is reachable, and perform duplicate address detection. The Code field value of NA message is 0, and the role in address resolution is to respond to NS message. In addition, when the node changes in the link layer, NA message is actively sent out to inform the neighbor of the change of the node. After the node is started, a request is sent to the router through an RS message, and the prefix and other configuration information are requested for automatic configuration of the neighbor node. The RA message is used for responding to the RS message. Without inhibiting the release of the RA message, the router can periodically release the RA message, wherein the RA message comprises prefix information options and information of some flag bits. Wherein each node corresponds to a terminal device.

In some embodiments, step 101 comprises:

step 1011: and determining a message notification period according to the neighbor discovery protocol.

In specific implementation, a message notification period of a route notification message in a neighbor discovery protocol defaults to 1 second. However, the message notification period may be manually set, and is not limited herein.

Step 1012: and the control message notification terminal sends the route notification message according to the message notification period.

Step 1013: and determining a neighbor request terminal which receives the route notification message, and controlling the neighbor request terminal to send the route request message with the first neighbor identifier to the message notification terminal.

Step 1014: and after the message notification terminal is detected to receive the route request message, sending an identification notification message with a second neighbor identification to the neighbor request terminal.

Step 1015: and after detecting that the neighbor request terminal receives the identification notification message, obtaining a terminal equipment discovery result.

In the implementation, the message notification terminal sends an RA message to all the communicable nodes in a multicast mode, and the RA message does not carry a neighbor identifier at this time, but is only used for searching the nodes capable of establishing the neighbor relation. All terminal devices receiving the RA message are regarded as neighbor request devices, and the neighbor request devices control the neighbor request devices to send the RS message carrying the first neighbor identification to the message notification terminal at the moment so as to request the neighbor relation establishment of the message notification terminal, and the neighbor request devices mark the neighbor states of the neighbor request devices and the message notification terminal as 0 at the moment to indicate that the neighbor relation is not successfully established. The first neighbor identifier is an identifier of a neighbor of the neighbor request terminal, wherein the neighbor request terminal is a message notification terminal.

After the message notification terminal receives the marked RS message, if the neighbor relation can be established, the message notification terminal is controlled to send the RA message carrying the second neighbor identification to the neighbor request terminal so as to respond to the request for establishing the neighbor relation sent by the neighbor request terminal. The message notification terminal marks the neighbor state of the message notification terminal and the neighbor request terminal as 1, which indicates that the neighbor relation is successfully established with the neighbor request terminal. The second neighbor identifier is an identifier of a neighbor of the neighbor request terminal serving as the message notification terminal.

After the neighbor solicitation terminal receives the marked RA message, if the neighbor relation can be established, the neighbor solicitation terminal marks the neighbor state of the neighbor solicitation terminal and the message notification terminal as 1, which indicates that the neighbor relation is successfully established with the message notification terminal. And after the neighbor relation between the message notification terminal and the neighbor request terminal is determined, obtaining a terminal equipment discovery result of the neighbor request terminal.

Step 1016: and constructing a neighbor topological relation according to the discovery result of the terminal equipment.

In the specific implementation, all terminal equipment discovery results of the neighbor solicitation terminals are integrated, so that all terminal equipment capable of establishing a neighbor relation with the neighbor solicitation terminals are obtained, and the neighbor topological relation is obtained.

Step 102: and determining the sending equipment and the receiving equipment in the neighbor topological relation, determining the sending packet transmission network equipment corresponding to the sending equipment, and establishing a service sensing channel between the sending equipment and the sending packet transmission network equipment according to the simulated service requirement.

In the implementation, any one of the terminal devices in the neighbor topological relation is designated as a transmitting device based on the established neighbor topological relation, the transmitting device is utilized to forward the simulated service requirement to the transmitting SPTN device corresponding to the transmitting device through the service perception protocol, and the transmitting SPTN device is utilized to carry out service perception so as to establish a service perception channel between the transmitting device and the transmitting packet transport network device according to the simulated service requirement.

The process for establishing the service awareness channel comprises the following steps:

the SPTN sending device perceives the online of the sending device through an NDP message;

the sending equipment exchanges topological connection relation and simulate service requirements with the SPTN sending equipment through a link state message LSP, a whole sequence message CSNP and a partial sequence message PSNP of a service perception protocol;

The sending SPTN device obtains an online event of the sending device (the online event indicates that the sending device needs to send service data, for example, determines the online event by obtaining a service transmission request), and senses a network connection relationship between the sending device and the sending SPTN device;

And under the condition that service connection needs to be created, the sending equipment sends service connection requirements to the sending SPTN equipment through the service announcement message SCRP so that the sending SPTN equipment creates a service perception channel between the sending equipment and the sending equipment.

Step 103: and establishing a service bearing path between the sending equipment and the receiving equipment according to the service sensing channel, wherein the service bearing path corresponds to the current service requirement.

In particular, the service bearer path includes a working path and a protection path. The traffic bearer paths may include LSPs (label switched paths), tunels (TUNNELs), and PW (pseudowires), in particular. The upper controller determines the feature codes (such as TOS, DSCP, MAC, PORT, IP, etc.) of the service types such as video, audio, control data, network management, etc., and the current service demands such as the required guarantee level, bandwidth control, etc. The SPTN sending device can establish a service bearing path corresponding to the current service requirement according to the current service requirement

Step 104: and analyzing the current service requirement into an access control list corresponding to the transmitting packet transport network equipment, and transmitting the access control list to the receiving packet transport network equipment corresponding to the receiving equipment.

In implementation, the upper layer controller may be used to interpret the current service requirement as an access control list (Access Control List, ACL) and a quality of service (Quality of Service, QOS) rule corresponding to the SPTN device, and issue the access control list and the quality of service (Quality of Service, QOS) rule to the receiving SPTN device corresponding to each receiving device.

Step 105: and controlling the receiving packet transport network equipment to distribute the service bearing path according to the access control list and the current service requirement to obtain a target service bearing path for carrying out service transmission between the sending equipment and the receiving equipment.

In implementation, the receiving SPTN device distributes a service bearer path established before for service data according to ACL and QOS rules, so as to implement end-to-end service transmission.

Step 106: and controlling the receiving packet transport network equipment to acquire the basic resources on the target service bearing path, sensing the running state of the service management system according to the basic resources, and adjusting the target service bearing path according to the basic resources if the running state is abnormal.

In the implementation, the basic resource is basic information of network elements, ports and topological links. The upper layer controller only needs to summarize basic parameters of basic resources of the SPTN equipment, and can adjust a target service bearing path subsequently according to the summarized basic parameters. Wherein the basic parameters include, but are not limited to: network element operation status, port rate, port occupation status, port operation status, topology link actual bandwidth, topology link residual bandwidth, and topology link operation status. When the parameter value in the basic parameter is abnormal, the running state of the service management system can be determined to be abnormal, and the target service bearing path needs to be adjusted according to the basic resource so as to change the running state of the service management system into a normal state. Illustratively, the adjustment method includes changing tunnels of the protection path, changing traffic paths, and the like.

In summary, the method for adjusting the operation state of the service management system provided by the embodiment of the application can determine the neighbor topology relationship between different terminal devices; determining a transmitting device and a receiving device in a neighbor topological relation, determining a transmitting packet transmission network device corresponding to the transmitting device, and establishing a service sensing channel between the transmitting device and the transmitting packet transmission network device according to the simulated service requirement; establishing a service bearing path between a transmitting device and a receiving device corresponding to the current service demand according to the service sensing channel; analyzing the current service demand into an access control list corresponding to the sending packet transport network equipment, and sending the access control list to the receiving packet transport network equipment corresponding to the receiving equipment; the method comprises the steps that a receiving packet transport network device is controlled to distribute a service bearing path according to an access control list and current service requirements, and a target service bearing path for service transmission between a sending device and a receiving device is obtained; and controlling the receiving packet transport network equipment to acquire the basic resources on the target service bearing path, sensing the running state of the service management system according to the basic resources, and adjusting the target service bearing path according to the basic resources if the running state is abnormal. By constructing the target service bearing path which can be actively perceived by the receiving packet transport network equipment, the receiving packet transport network equipment can actively know the running state of the target service bearing path, adjust the target service bearing path according to the running state in real time, improve the smoothness of service data transmission of the service management system and improve the use experience of users

In some embodiments, as shown in fig. 3, the establishment of a traffic aware channel between a sending device and a sending packet transport network device according to an analog traffic demand includes:

Step 301: and controlling the transmitting device to transmit the neighbor discovery protocol message to the transmitting packet transmission network device.

In the implementation, the SPTN device supports different service system access such as video, audio, control data, network management and the like. Therefore, service awareness needs to be realized by depending on an SPTN device, and the SPTN device supports service pipelining bearing and provides powerful support for realizing functions such as shaping, congestion avoidance, isolation, scheduling and protection of services. The functions provided by the service pipelining bearer are as follows: the method supports the pipelining bearing of a voice service system, a video service system, an IP monitoring system and a command control system, the pipelines are absolutely isolated, and the services of different pipelines are not affected mutually. Therefore, the sending device is controlled to send a neighbor discovery protocol message to the sending SPTN device so as to prompt that the sending SPTN device sending device is on line, and the sending SPTN device starts to operate.

Step 302: and in response to detecting that the transmitting packet transport network equipment receives the neighbor discovery protocol message, controlling the transmitting equipment and the transmitting packet transport network equipment to exchange neighbor topological relation and simulate service requirements through a link state message, a whole sequence message and a partial sequence message of a service awareness protocol.

In the implementation, after the sending SPTN device receives the neighbor discovery protocol message, the sending device exchanges the neighbor topology relationship and the simulated service requirement with the sending SPTN device through the link state message LSP, the whole sequence message CSNP and the partial sequence message PSNP of the service perception protocol, so that the sending SPTN device can perceive the receiving device corresponding to the sending device according to the neighbor topology relationship, and further perform subsequent service data transmission; the transmission SPTN equipment can know the service transmission requirement of the terminal equipment by exchanging the analog service requirement, and is convenient for transmitting service data according to the service requirement.

Step 303: and in response to the detection of the completion of the exchange, controlling the sending equipment to send the service connection requirement to the sending packet transport network equipment through the service announcement message.

When the method is implemented, after the exchange is completed, the sending SPTN equipment acquires the online event of the sending equipment, senses the network connection relation between the sending equipment and the sending SPTN equipment, can perform data interaction between the sending equipment and the sending SPTN equipment, and controls the sending equipment to send service connection requirements to the sending packet transport network equipment through service announcement messages at the moment for transmission and identification of service data.

The simulated service requirement is a light-weight requirement formed by simulating the real service requirement, and is used for simulating the exchange process of the real service requirement in the service sensing channel.

Step 304: and in response to the detection that the sending packet transport network equipment receives the service connection requirement, controlling the sending packet transport network equipment to establish service connection between the sending equipment and the sending packet transport network equipment according to the service connection requirement so as to obtain a service sensing channel.

When the method is implemented, after detecting that the SPTN transmitting equipment receives service connection requirements, the SPTN transmitting equipment responds to the service connection requirements, service connection between the SPTN transmitting equipment and the packet transmission network transmitting equipment is established according to the service connection requirements, and a service sensing channel is obtained.

In some embodiments, the traffic-bearing path includes a working path and a protection path; as shown in fig. 4, a service bearer path corresponding to a current service requirement between a sending device and a receiving device is established according to a service awareness channel, including:

Step 401: and controlling the sending equipment to acquire the current service requirement, and synchronizing the current service requirement to the equipment for sending the packet transmission network according to the service sensing channel.

In specific implementation, the current service requirement is a real service requirement that the sending device needs to execute, and after the sending device obtains the current service requirement, the sending device indicates that corresponding service data needs to be sent to the receiving device, so that the current service requirement needs to be synchronized to the sending SPTN device according to the service sensing channel, so that the sending SPTN device senses the current service requirement.

Step 402: and controlling the transmitting packet transport network equipment to establish a working path and a protection path for connecting the transmitting equipment and the receiving equipment according to the current service requirement.

In specific implementation, after the SPTN transmitting device senses the current service requirement, a working path and a protection path for connecting the transmitting device and the receiving device are established according to the current service requirement, wherein the working path is established for transmitting service data, and the protection path is established for protecting the service data from being attacked or stolen. The working path and the protection path constitute a traffic bearer path for transmitting traffic data.

In some embodiments, as shown in fig. 5, controlling a receiving packet transport network device to allocate a service bearer path according to an access control list and a current service requirement to obtain a target service bearer path for performing service transmission between a sending device and a receiving device, includes:

step 501: and controlling the receiving packet transmission network equipment to identify the performance parameters of each target service bearing path according to the access control list.

In particular, the access control list is an ordered rule set composed of a series of admit or dense sentences, which classifies messages by matching the relevant fields of the messages. The ACL itself is just a set of rules, and can only distinguish a certain class of messages, much like a "tool", and when filtering for a particular flow is implemented by the ACL, it is necessary to invoke an ACL that is already defined in the appropriate application.

ACLs are a very widely used tool that can be invoked in a variety of scenarios. The main usage scenarios of ACLs include:

The method is called by a traffic policy and used for filtering traffic, and can be based on elements such as source and destination IP addresses, protocol types, port numbers and the like;

Called in route-policy for matching a particular routing prefix, thereby executing a routing policy;

Invoking in the VPN for matching the data stream of interest;

Invoked in the policy deployment of the firewall for matching traffic.

An access control list is a set of "rules" in the form of a list. The ACL can identify elements such as a source IP address, a destination IP address, a protocol type, a source destination port and the like in one IP packet, so that matching of messages can be performed for the elements.

For example, a network device may be continuously receiving various network traffic over an interface, and if it is desired to identify certain ones of those traffic for further action, then an ACL may be used. Furthermore, in addition to being able to be used to match data, ACLs can also be used to match routes, enabling us to deploy different routing policies for different routes. The ACL contains a plurality of rules, each rule has a number, all rules are arranged according to the size of the number of the rule, and the smaller the number is, the earlier the ordering is. In each rule, a match condition may be defined, along with a corresponding permit/reject action. In the execution process of the ACL, equipment starts to calculate and match from the rule with the minimum number in the ACL, if a matched object meets the matching condition in the rule, the action defined by the rule is executed, and other rules are not calculated downwards; and if the matched object does not meet the matching condition in the rule, continuing to match the next rule.

Therefore, the current service requirement is resolved into the access control list corresponding to the sending packet transport network device, so that each rule in the access control list can be set on the premise of meeting the current service requirement, but the establishment of the rule needs to correspond to the sending SPTN device, because the sending SPTN device has a corresponding function limitation, for example, the maximum transmission speed of the sending SPTN device is 100M/s, if the current service requirement needs to have a transmission speed of 120M/s, the establishment of the rule in the ACL according to the transmission speed of 120M/s is unreasonable, and therefore, the corresponding matching rule in the ACL needs to be determined by combining the current service requirement on the basis of the performance of the sending SPTN device.

The performance parameters of the service carrying path may be transmission bandwidth, transmission delay, packet loss rate of data, etc.

Step 502: and determining the service quality of each standard service bearing path according to the performance parameters.

In the specific implementation, the more the number of rules in the ACL is satisfied in the performance parameters, the better the service quality of the target service bearing path is, the more current service line requirements can be satisfied in the process of service data transmission, and the higher the service quality of the target service bearing path is.

Step 503: and determining the quality requirement according to the current service requirement.

In particular, by way of example, if there are 10 rules in the current business requirement, determining the quality requirement from the current business requirement may be to satisfy at least 8 of the rules.

Step 504: and determining a target service quality meeting the quality requirement, and determining a service bearing path corresponding to the target service quality as a target service bearing path.

In specific implementation, illustratively, if there are 10 rules in the current service requirement, the quality requirement may be to satisfy at least 8 rules, and the service bearer path satisfying 8 rules, satisfying 9 rules, and satisfying 10 rules is determined as the target service bearer path.

In some embodiments, as shown in fig. 6, controlling the receiving packet transport network device to acquire the basic resource on the target service bearer path, and sensing the operation state of the service management system according to the basic resource includes:

step 601: and controlling the receiving packet transmission network equipment to acquire the basic resources on the standard service bearing path according to the preset time interval, and judging whether the basic resources are changed or not.

In the implementation, the basic resource is basic information of network elements, ports and topological links. The upper layer controller only needs to summarize the basic parameters of the basic resources of the SPTN equipment, and can judge whether the basic resources are changed or not according to the summarized basic parameters. Wherein the basic parameters include, but are not limited to: network element operation status, port rate, port occupation status, port operation status, topology link actual bandwidth, topology link residual bandwidth, and topology link operation status.

Step 602: and determining that the running state of the service management system is a normal state in response to the basic resource not being changed.

When the basic parameters are not abnormal in parameter value, the running state of the service management system can be determined to be a normal state, the target service bearing path is not required to be adjusted according to the basic resources, and the transmission of service data meets the current service requirement.

Step 603: and determining the operation state of the service management system as an abnormal operation state in response to the change of the basic resource.

When the basic parameters have abnormal parameter values, the operation state of the service management system can be determined to be an abnormal state, and the target service bearing path needs to be adjusted according to the basic resources so as to change the operation state of the service management system into a normal state. Illustratively, the adjustment method includes changing tunnels of the protection path, changing traffic paths, and the like.

In some embodiments, as shown in fig. 7, the protection path includes at least one tunnel path; the method for adjusting the target service bearing path according to the basic resource comprises the following steps:

Step 701: the type of resource in which the change occurs in the base resource is determined.

Step 702: and responding to the path running state of which the resource type is the tunnel path and the path running state is the descending state, determining a candidate tunnel path according to the first running parameter of the protection path, and determining a target tunnel path meeting the current service requirement in the candidate tunnel path.

Step 703: and responding to a second operation parameter of which the resource type is the working path, and adjusting unprotected business data corresponding to the current business requirement according to the second operation parameter, wherein the unprotected business data are business data which do not need to use a protection path when being transmitted.

When the operation state of any tunnel path of the protection path is descending or the first operation parameter of any tunnel path of the protection path is abnormal, the resource type is the path operation state of the tunnel path, and the protection path of the protection service needs to be adjusted; when the second operation parameter of the working path of the unprotected traffic is abnormal, the second operation parameter of which the resource type is the working path is determined, and the working path for transmitting the unprotected traffic needs to be adjusted. The first operating parameter and the second operating parameter include: the minimum number of abnormal tunnels, the minimum number of hops of a route, time delay, bandwidth balance and the like. And the second operating parameter comprises: minimum hop count for routing, latency, bandwidth equalization, etc.

The running state of the tunnel path is generally related to the safety of the stock service, and if the running state is reduced, the protection path of the stock service needs to be adjusted, so that the safety of the service transmission process is ensured. The operation parameters are related to the rationality of the stock service, and if the first operation parameters are abnormal (such as the maximum value and the minimum value have larger difference), the protection path of the stock service needs to be adjusted to ensure the rationality of the operation. If the second operation parameter is abnormal (such as the difference between the maximum value and the minimum value is larger), the working path of the stock service needs to be adjusted to ensure the rationality of service transmission

The process of adjusting the protection path of the stock traffic includes: and selecting a proper minimum number of target tunnel paths of at least abnormal tunnels from the candidate tunnels according to the minimum hop count, time delay and bandwidth balance of the route. Illustratively, the receiving SPTN device may set parameters related to the tunnel path locally, such as: the minimum hop count, time delay, bandwidth balance and the like of the route are sent to the controller, the upper layer controller selects a plurality of candidate tunnels according to the parameters provided by the SPTN receiving equipment, and sends the candidate tunnels to the SPTN receiving equipment, so that the SPTN receiving equipment selects a proper at least minimum number of route tunnel paths of the abnormal tunnels from the candidate tunnels according to the local condition, and the adjustment of the protection paths is realized.
