Example 1
Fig. 1 is a flowchart of a network service management method according to an embodiment of the present invention, where the method may be performed by a network service management device, and the network service management device may be implemented in hardware and/or software, and the network service management device may be configured in an electronic device with data processing capability.
As shown in fig. 1, the method includes:
s110, acquiring a network service request, and storing data matched with the network service request into a context.
The network service can send the network configuration to the corresponding network node through the flow node in the responsibility chain, so as to achieve the purpose of controlling the flow forwarding. The flow node is a specific execution step in the responsibility chain, and is used for processing the received request to determine the subsequent trend of the responsibility chain. The network service is a configuration required by the traffic engineering issued to the switch and the router equipment, for example, two-layer and three-layer VPN services based on forwarding modes such as SR tunnel, SR-Policy, SRv6-Policy and the like. The network service data may be, for example, a virtual routing forwarding table, device information, etc. that are transferred in the entire service through the context, and released with the context after the service ends.
When executing a network service, generally, all flow nodes are traversed through a static responsibility chain to determine whether to execute a certain function module or add a required function module before executing the network service. The former makes the static responsibility chain structure too long to affect the network transmission performance, and the latter makes the static responsibility chain process complex, which is only suitable for the scene of creating responsibility chain in the manual dragging task of the page.
In view of the above problems, the embodiment of the invention connects each flow node through the dynamic responsibility chain, so that the network service can be rapidly executed by accessing the dynamic responsibility chain, the data analysis processing capacity of executing the complex network service is improved, the manual operation amount is reduced, and the network service creation speed is improved.
The dynamic responsibility chain is created through a double-linked list mode, each flow node in the double-linked list can comprise a flow node number, an execution service function, a rollback service function and two pointers, wherein the two pointers respectively point to a subsequent flow node and a predecessor flow node, and the rollback service rolls back memory information, hard disk storage, network element configuration and the like modified in the execution service of the flow node until the execution service is restored to the state before execution. It should be noted that the rollback service is triggered only when an anomaly occurs in the flow.
In the embodiment of the invention, the data matched with the network service request is stored in the context, so that the data transmission is realized. The context can be used as a temporary data storage medium, each flow node carries out data transmission through the context, the data is stored in the context in the form of key value pairs, namely, one keyword corresponds to one type of data, the data formats of writing and reading the context through one keyword are consistent, and the context is destroyed when the network service execution is completed.
S120, analyzing the data matched with the network service request in the context through the data analysis node in the responsibility chain to obtain the target service type and the target configuration information, and storing the target service type and the target configuration information in the context.
The flow nodes in the responsibility chain may be divided according to the functions of the contained service, such as a data analysis node, a flow selection node, a network element configuration node, a data storage node, and the like.
The data analysis node may be a node that performs data processing on the network service request. The target service type may be determined according to the function of the target service, and may be, for example, an add function, a delete function, or a modify function. The target configuration information may be information for implementing a target service function.
It should be noted that, if the target configuration information includes a certain network element resource and the network service request does not include the network element resource, the data analysis node may allocate the network element resource for the target service through the resource pool. After the allocation of the network element resources is completed, if the data analysis node triggers the rollback service, the network element resources need to be released.
S130, determining a target configuration node matched with the target service type through a flow selection node in a responsibility chain, and adding the target configuration node into the responsibility chain.
The flow selection node may be a node that controls the responsibility chain, and may determine the trend of the flow node in the responsibility chain according to the target service type and the target configuration information. The target configuration node may be a node that implements the target traffic function.
Optionally, adding the target configuration node to a responsibility chain includes: and determining the insertion position of the target configuration node in the responsibility chain according to the execution sequence of the target service type in the network service.
The target configuration node may be represented by a node number, where the node number may represent an execution order of the target service type in the network service. And determining the insertion position of the target configuration node in the responsibility chain according to the node number. By such an arrangement, flexibility in the operation of the liability chain can be improved.
Fig. 2 is a schematic flow chart of a joining target configuration node according to an embodiment of the present invention. As shown in fig. 2, if the node number of the added target configuration node is 2, the subsequent node of the node 1 points to the node 3 and the predecessor node of the node 3 points to the node 1 before the target configuration node is not added to the responsibility chain; after the target configuration node is added into the responsibility chain, the subsequent node of the node 1 points to the target configuration node, the subsequent node of the target configuration node points to the node 3, the precursor node of the node 3 points to the target configuration node, and the precursor node of the target configuration node points to the node 1.
Before the target configuration node is added to the responsibility chain, the network traffic is executed in the execution order of node 1- > node 3, and is rolled back in the execution order of node 3- > node 1. After adding the target configuration node to the responsibility chain, the network traffic is performed in the order of execution of node 1- > target configuration node- > node 3, and rolled back in the order of execution of node 3- > target configuration node- > node 1. If an exception occurs at the target configuration node, rollback is performed in the order of execution of the target configuration node- > node 1.
S140, acquiring the target configuration information and the target service type in the context through the target configuration node, and executing the network service matched with the target service type on the target configuration information.
And acquiring the target configuration information and the target service type in the context through the target configuration node added in the responsibility chain, and executing the network service matched with the target service type according to the acquired target configuration information.

The access route is used for opening a route between a CE (Customer Edge device) and a PE (Provider Edge device), so that Customer traffic can be accessed to a Virtual Private Network (VPN) for forwarding, and the access route can select one or more combinations of BGP access, static routing access and OSPF access.
It should be noted that, according to the data matched with the network service request, multiple types of forwarding policies and access routes can be determined.
