Description

SDN northbound interface operation monitoring method and device

technical field

The embodiment of the present invention relates to the technical field of network management, in particular to a method and device for monitoring the operation of an SDN northbound interface.

Background technique

The controller is the core of the SDN network architecture, which is used to manage and control the underlying network resources, and at the same time provide the interface of the network resources for the application. At present, there is no relevant standard specification for controller implementation in the industry, and it is mainly implemented by manufacturers and developers in a private manner. The function of the northbound interface is to provide external applications with the ability to call abstract network resources and controller services through the API. At present, the northbound interfaces of mainstream controllers are the same for all parts. Typical API interfaces include adding/modifying/deleting networks, subnets, and ports, and obtaining related information. Commonly used northbound interface technologies include RESTful (Representational State Transfer, REST), OSGI (Open Service Gateway Initiative, Open Service Gateway Protocol), and RPC (Remote Procedure Call, Remote Procedure Call) protocols, etc.

At present, the northbound interface of the SDN controller uses different interface protocols to connect with the upper-layer business system and management system. The operation of the interface is the fundamental guarantee for the operation of the network and business. Peacekeeping management provides support means and lays the foundation for business development.
