Problems solved by technology

First, the field is limited to the routing field, and other fields cannot open interfaces through I2RS
Second, it is still in the conceptual stage, and the specific implementation protocol of I2RS has not yet been proposed.
However, the field of NETCONF is only in the field of configuration, while SDN also includes the field of network operations (such as modifying routing table entries, forwarding table entries, etc.), so it is not sufficient to use NETCONF as an SDN implementation protocol
[0007] To sum up, none of the existing SDN implementation protocols can perfectly solve the conflict between the SDN scenario and the existing network. For example, openflow has insufficient support for the smooth evolution of the existing network. I2RS has not yet implemented a protocol. Insufficient layer support

Embodiment Construction

[0059] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0060] The technical problem to be solved by the present invention is: in the field of SDN, the software definition of the network equipment is completed through the programmable interface RPC provided by the network equipment. At present, the main SDN protocols are all continuation of the idea of ​​the traditional network, by defining the data model of the logical entity, and then modifying the logical entity through the general CRUD (create, obtain, update, delete) operation. But this data model has the following problems:

[0061] 1. Since the data model directly defines the data items of entities, different manufacturers must implement them according to these data items, which increases the difficulty of implementation by different manufacturers. Fr...

Abstract

The invention provides a method for operating a network logic entity, a client and a proxy server. The method comprises the following steps: when a connection of the client and the proxy server is established, the client carries out capability exchange with the proxy server; after the connection with the proxy server is established, the client finds a function provided by the proxy server; the client calls the function to call a RPC interface by means of a remote process and sends a RPC call request to the proxy server; and the client operates the network according to an execution result of the proxy server on the process according to the RPC call request and the function of the proxy server. The method provided by the scheme of the invention can be used for achieving SDN based on RPC, and enabling a user to conveniently operate the network logic entity.

Description

technical field [0001] The present invention relates to the communication field, in particular to an operation method, a client and an agent for realizing network logic entities in an SDN (software-defined network) based on RPC (using remote procedure call). Background technique [0002] Software-defined networking (SDN) is a new network architecture that is currently booming. Its essence is to realize the intelligence and automation of the network through software-defined methods to achieve better network manageability. [0003] At present, the main implementation methods of SDN are as follows: [0004] The Openflow protocol, the Openflow protocol originated from a paper written by Stanford professor nick McKeown in 2008, and has now been developed to version 1.4. It is the most famous implementation protocol in the entire SDN field. The essential idea is to decouple the control plane and the forwarding plane, separate the control plane from the network equipment, and use...
