Detailed Description
The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.
The traditional IP network is a communication mode taking a server as a center, addresses are used for identifying the server, data acquisition needs to access the data server, the server directly influences the time delay in the distance of the network or a physical position, and a named data network takes data contents as the center, sets a content name as an addressing mode, establishes a routing table based on the content name for communication, and decouples the relationship between the data contents and the server position.
The NDN (Named Data Networking) content-based communication mode is beneficial to realizing cloud network integration, and cloud resources and network resources integration can provide cloud services by adopting a cloud service-based communication mode.
The invention provides a service providing mode under cloud network convergence, which is beneficial to providing services for users by cooperation of a plurality of clouds in a network.
A flow diagram of some embodiments of a method performed by a cloud node in a service providing method of the present disclosure is shown in fig. 1.
In step 110, the cloud node obtains a cloud service request, which may include a name or identification of the requested service. In some embodiments, the cloud service requests nodes from the last hop, such as other cloud nodes or routing nodes, user nodes, and the like.
In step 120, the cloud node determines whether it has resources, such as files or data resources, required by the requested service. If the cloud node determines that it has the required resources, step 130 is executed.
In some embodiments, the cloud node is pre-cached with a portion of the resources, and may also request and cache resources from other nodes in the network in order to provide cloud services. In some embodiments, the cloud node may establish the CS interest table according to the cached resources, and further match the required resources with the cloud service cache information in the CS interest table, and if the matching is successful, it is determined that the required resources are provided, otherwise, the required resources are not provided. In some embodiments, the cloud node may update the CS interest table according to a change of its own resource, for example, according to a predetermined frequency. In some embodiments, the cloud node may send a cloud service request to other nodes in the network to acquire resources and cache the resources, and further update the CS interest table to extend services that the cloud node can provide.
In step 130, the cloud node determines to provide a corresponding cloud service or feed back a corresponding resource based on the resource cached by the cloud node.
In some embodiments, the cloud node may distinguish the types of the cloud service requests, and provide the corresponding cloud service to the user if the cloud service request is a request for providing the cloud service for the user request; if the cloud service request is a request for requesting the cache of the corresponding resource by other nodes (such as cloud nodes) in the network, feeding back the corresponding resource.
In some embodiments, the cloud node may determine the type of the cloud service request by identifying a source node of the cloud service request, for example, if the source node of the cloud service request is a user node, providing a corresponding cloud service; and if the source node of the cloud service request is a non-user node, feeding back resources corresponding to the cloud service request through a port (or interface) for acquiring the cloud service request.
Based on the manner in the above embodiment, the cloud node can make a corresponding reaction based on the cached resources of the cloud node and the received cloud service request, so as to provide the resources of the cloud node to other cloud nodes or users in the network, and implement service response and interaction based on the resources.
In some embodiments, as shown in fig. 1, the service providing method of the present disclosure may further include step 140. In step 120, if the cloud node determines that it does not have the resources required for the requested service, step 140 is executed.
In step 140, the cloud node determines a target forwarding port according to a predetermined routing policy and the cloud service routing information, and forwards the cloud service request. In some embodiments, the cloud service routing information is generated and updated by the cloud node according to the local service resource and the received routing interaction information, and the cloud service routing information may include a naming prefix of the cloud service, a port corresponding to the cloud service, a path packet loss rate, a time delay, and the like.
Based on the method in the embodiment, the cloud node can search the cloud node capable of providing the corresponding resource and forward the cloud service request under the condition that the cloud node does not have the resource required by the cloud service request, so that the cloud service request can be received by other cloud nodes in the network, the corresponding resource is provided for the node requiring the service or the resource, the success rate of providing the cloud service is improved, and the user experience is improved.
In some embodiments, as shown in fig. 1, the service providing method of the present disclosure may further include step 150.
In step 150, the cloud node updates the PIT according to the cloud service request and the target forwarding port when determining that the resource corresponding to the cloud service request is not available. In some embodiments, the steps 140, 150 are not in a fixed order and may be processed in parallel.
In some embodiments, the process of updating the PIT may be as shown in fig. 2.
In step 251, the cloud node records the name of the cloud service, the port receiving the cloud service request, and the target forwarding port in a PIT, where the PIT is mainly used to track the request packet that is not satisfied currently.
In step 252, the cloud node determines whether a cloud service record corresponding to the cloud service request is already recorded in the PIT. If the cloud service corresponding to the cloud service request is not recorded in the PIT, execute step 255; if the cloud service corresponding to the cloud service request is already recorded in the PIT, step 253 is executed.
In step 253, the cloud node determines whether a duplicate entry has occurred in the PIT. In some embodiments, the duplicate entries refer to more than two entries where the name of the cloud service, the port receiving the cloud service request, and the target forwarding port are all the same. If duplicate entries appear in the PIT, go to step 253; otherwise, step 255 is performed.
In step 254, the PIT is deduplicated and only one entry remains for the duplicate. The PIT update operation is completed.
In step 255, the PIT update operation ends.
Based on the mode in the above embodiment, the current unsatisfied request can be recorded and updated in time, so that the storage resource waste, the service resource waste and the service providing confusion caused by the repetition of the recorded request can be avoided, and the stability of the cloud service is ensured.
In some embodiments, when the cloud node needs to establish the cloud service, the cloud node needs to be based on parameters and templates corresponding to the cloud service. The cloud nodes can store parameters and templates corresponding to some services, and the parameters and the templates can be transmitted among the cloud nodes. If the cloud node has the parameters and the templates required by the cloud service to be established, establishing the service based on the stored resources; if the cloud node does not have corresponding parameters and templates, the cloud node needs to obtain the parameters and the templates from other cloud nodes. In addition, the cloud node can update the storage of the cloud node according to the parameters and the template information transmitted in the network.
In some embodiments, the cloud node may determine the corresponding parameter, template, from the name or identity of the cloud service.
A flowchart of further embodiments of the method performed by the cloud node in the service providing method of the present disclosure is shown in fig. 3.
In step 361, the cloud node obtains cloud service data information, where the cloud service data information includes a cloud service name, a resource requirement, a configuration template, and a service source.
In step 362, the cloud node determines whether a resource corresponding to the cloud service data information is available. If the cloud node has the resource corresponding to the cloud service data information, step 363 is executed.
In step 363, the cloud node determines to provide the corresponding cloud service or forward cloud service data information according to the source node of the cloud service request corresponding to the cloud service name. In some embodiments, the cloud node also caches configuration parameter (such as configuration template) information carried in the cloud service data information under the condition of forwarding the cloud service data information, so that the configuration information storage of the cloud node is enriched, and the efficiency of subsequent cloud service establishment is improved.
In some embodiments, the cloud node may determine a subsequent processing manner according to a type of the cloud service request corresponding to the cloud service data information. In some embodiments, if the cloud service request is a request for a user to request provision of cloud services, the user is provided with the corresponding cloud services; if the cloud service request is a request for requesting caching of the corresponding resource by other nodes (such as cloud nodes) in the network, the cloud nodes needing the resource also need the cloud service data information, so that the cloud service data information is sent through a port for acquiring the corresponding cloud service request, and the node for initiating the cloud service request can receive the cloud service data information.
In some embodiments, the cloud node may determine the type of the cloud service request by identifying a source node of the cloud service request, and if the source node of the cloud service request is a user node, construct a corresponding cloud service based on cloud service data information, and provide the cloud service to the user; and if the source node of the cloud service request is a non-user node, feeding back cloud service data information by acquiring a port of the cloud service request.
Based on the mode in the embodiment, the cloud node can store the configuration information and provide the service under the condition that the cloud node can provide the corresponding cloud service after acquiring the configuration information required for establishing the cloud service; meanwhile, the cloud node initiating the resources corresponding to the cache cloud service in the network can receive the corresponding configuration information, and the success rate of cloud service establishment is improved.
In some embodiments, as shown in fig. 3, the service providing method of the present disclosure may further include step 364. In step 362, if the cloud node does not have the resource corresponding to the cloud service data information, step 364 is executed.
In step 364, the cloud node deletes the cloud service data information.
Based on the mode in the embodiment, the cloud node can identify and delete the cloud service data information which is not needed by the cloud node, and the utilization rate of the storage space is improved.
In some embodiments, besides the cloud node which has service resources and can provide cloud services, the routing node which does not have service resources and can not provide cloud services can also perform coordination operations in the construction and the provision of the cloud services. A flow diagram of some embodiments of a method performed by a routing node in a service provisioning method of the present disclosure is shown in fig. 4A.
In step 410, the routing node obtains a cloud service request.
In step 420, the routing node determines a target forwarding port according to a predetermined routing policy and the cloud service routing information, and forwards the cloud service request. In some embodiments, the cloud service routing information is generated and updated by the routing node according to the received routing interaction information, wherein at least one of the routing node and the cloud node in the network sends the cloud service routing information of the routing node and the cloud node to other nodes in the network, so that the other cloud nodes and the routing node can record and update the routing information conveniently.
In some embodiments, the predetermined routing policy may include selection according to remaining resources of the cloud node, selection according to path length, selection according to cloud node priority, selection according to user level, and the like, and in some embodiments, the predetermined routing policy may be set or modified according to requirements.
Based on the method in the embodiment, the routing node can forward the cloud service request to the forwarding port of the cloud node with the corresponding resource, so that the cloud service request reaches the cloud node, and the success rate of cloud service establishment and resource intercommunication is improved.
In some embodiments, the routing node may also update the PIT according to the cloud service request and the target forwarding port. In some embodiments, the process of updating the PIT by the routing node may be similar to that of the cloud node, for example, the PIT of the routing node is updated by using logic as in fig. 2, so that the currently unsatisfied request can be timely recorded and updated, storage resources, waste of service resources, and confusion of service provision caused by repetition of the recorded request are also avoided, and the stability of the cloud service is ensured.
A flow diagram of further embodiments of methods performed by a routing node in a service provisioning method of the present disclosure is shown in fig. 4B.
In step 430, the routing node obtains cloud service data information.
In step 440, the routing node determines whether the cloud service corresponding to the cloud service data information is recorded in its PIT. If the information is recorded in the PIT, determining that the routing node has the capability of forwarding the cloud service data information to the cloud node needing the information, and executing step 450; otherwise, it is determined that the routing node does not have the capability of forwarding the cloud service data information to the cloud node that needs the information, and step 460 is performed.
In step 450, the routing node forwards the cloud service data information according to the record in the PIT.
In step 460, the routing node deletes the cloud service data information.
Based on the mode in the embodiment, the routing node can forward the cloud service data information to the cloud node needing the information according to the PIT, so that the cloud node can conveniently establish the corresponding cloud service in time, and the success rate and the efficiency of establishing the cloud service are improved.
In some embodiments, the state of the network node may be switched between the routing node and the cloud node, and the network node may determine its state by determining whether it has a CS interest table. If the network node has the CS interest table, it is determined that the network node is a cloud node, and after receiving the cloud service data information, the operation performed by the cloud node in the embodiment shown in fig. 3 is performed. If the network node does not have the CS interest table, it is determined that the network node is a routing node, and after receiving the cloud service data information, the operation performed by the routing node in the embodiment shown in fig. 4B is performed.
Based on the mode in the embodiment, the network node can be switched between the states of the routing node and the cloud node, so that the operation flexibility of the network node is improved.
A schematic diagram of some embodiments of a service provisioning method of the present disclosure is shown in fig. 5. The nodes in the network may include routing nodes and cloud nodes. Each cloud node (e.g., N1 to N4) discovers locally available cloud services, generates a cloud service information base, and establishes a CS interest table, which may be, in some embodiments, as shown in a cloud service CS cache table in fig. 5, store services that can be provided, corresponding resources, configuration templates, and source information of the templates. The contents of the tables in the figures are examples only. The cloud node can also calculate and generate local cloud service routing information, including information such as a naming prefix, a corresponding port, a path packet loss rate and time delay of the cloud service. In some embodiments, the cloud node advertises cloud service routing information into the network via Interest packets at regular intervals. In some embodiments, cloud service routing Information is stored in a FIB (forwarding Information dataBase) table.
Each network node (e.g., N1-N6) in the network, including the cloud node and the routing node, adds a route in the FIB according to the received routing information and local policy configuration. Unlike an IP network, a route of the same cloud service name may have a plurality of route entries having different path attributes.
When the network node determines a forwarding exit port, the network node defaults to select a path with low packet loss rate, low time delay and the like according to the path information in the strategy module and the FIB table.
In the figure, a cloud node N1 can provide a service, the corresponding resource is a, and the corresponding configuration template is Conf 1; the cloud node N1 may also provide a B service, where the corresponding resource is B and the corresponding configuration template is Conf 2. The cloud node N2 can provide a service C, the corresponding resource is C, and the corresponding configuration template is Conf 3; the cloud node N1 may also provide a D service, where the corresponding resource is D and the corresponding configuration template is Conf 4.
When the user node N0 initiates a cloud service request, the routing node N5 determines that it is a user request, and searches whether the cloud service corresponding to the request is in the PIT. If the cloud service request is not in the PIT, the cloud service request is a new request, and the PIT records a port for receiving the request and a port for forwarding; if the cloud service request is in the PIT, the cloud service request is a repeated request of the same service, and the PIT records a port for receiving the request and a forwarding port corresponding to the request. Routing node N5 forwards the cloud service request according to the determined forwarded port.
When the cloud node N3 receives the cloud service request, the cloud node first determines whether there is a cache corresponding to the cloud service in its CS interest table. If the CS has a corresponding cache, the cloud node further judges whether the CS is a user request, and if the CS is the user request, the cloud node builds a cloud service locally and provides the cloud service for a port receiving the cloud service request; if the request is not the user request, the cloud node forwards the cache content to the port receiving the request according to the cache content.
If the CS interest table of the cloud node does not have the cache of the cloud service, whether the record of the cloud service request exists is searched in the PIT module, and the PIT module judges whether the cloud service exists in the PIT module. If the cloud service request is not in the PIT, the request is a newly added request, and the PIT records a port for receiving the request and a port for forwarding; if the cloud service request is in the PIT, the cloud service request is a repeated request of the same service, the PIT records a port for receiving the request and a forwarding port corresponding to the request, and the PIT executes deduplication operation.
In addition, cloud service data information may also be transmitted in the network, for example, the node N2 sends the configuration template Conf3 to a port of the node N6, and the configuration template Conf3 is carried by the cloud service data information.
The routing node N6 searches whether a corresponding cloud service request record exists in the PIT according to the cloud service name carried in the cloud service data information, and if not, discards the data packet; and if the port information exists, forwarding the data packet to the corresponding port according to the port information recorded in the PIT.
When the cloud node exists, the node searches whether a cloud service request record exists in the PIT according to the cloud service name, if not, the data packet is discarded, and if so, whether the cloud service request is initiated by the user is judged.
If the cloud service request is initiated by the user, caching data such as a configuration template of the cloud service in the CS, and configuring the cloud service to provide the cloud service for the user according to the port information recorded in the PIT. If the cloud service request is not initiated by the user, forwarding the data packet to the corresponding port according to the port information recorded in the PIT, and caching data such as a configuration template of the cloud service in the CS.
Considering that the manner of providing part of cloud services is similar to the manner of providing data by the NDN, information such as a configuration template for providing the cloud services in the disclosure may be cached in one or more cloud nodes, and when a user requests the services, the cloud nodes build a cloud service environment locally by using the cached information to directly provide the cloud services. According to the characteristics of the cloud service, through the generation of the interest table and the routing table and the improvement of the use mode, the network nodes are divided into the cloud and the routing nodes, the differentiation function is executed when the requests and the data packets are processed, and the efficient and quick cloud service is realized. The network also inherits the excellent characteristics of NDN, endogenous safety, endogenous multicast and the like, and realizes the cooperative service provision among multiple clouds.
A schematic diagram of some embodiments of a network node 60 of the present disclosure is shown in fig. 6.
The acquisition unit 601 can acquire a cloud service request.
The first processing unit 602 can determine to provide the corresponding cloud service or feed back the corresponding resource according to the source node of the cloud service request when determining that the resource corresponding to the cloud service request is provided.
When the network node is used as a cloud node, the network node can make a corresponding reaction based on the cached resources and the received cloud service request, so that the self-owned resources are provided for other network nodes or users in the network, and the service response and interaction based on the resources are realized.
