Problems solved by technology

[0005] Disadvantages of the prior art: a service path protection method, controller, equipment and system, first of all, this invention is only service path protection, without fault monitoring function
It means that the SDN controller needs to calculate 2 or more service paths for the business in advance, which wastes the resources of the SDN controller. Secondly, when the service path fails and switches to a new service path, the invention cannot ensure that Is the new business path normal?

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] see figure 1 , Figure 4 , the system includes an SDN controller and a plurality of SDN switches, wherein the multiple SDN switches are connected to each other, and the SDN controller and the SDN switches interact through the added expansion interface; the SDN controller realizes the network topology Real-time detection and periodic detection of each link, and real-time monitoring of the status of SDN switches to maintain the overall network topology, so as to monitor the entire network and realize network fault monitoring and fault resolution.

[0039] The SDN controller includes: an OpenFlow module, an OpenFlow extension module, an event module, a topology module, a detection module, and a topology service path calculation module; the detection module further includes a real-time detection module and a periodic detection module.

Abstract

The invention relates to a system and a method for service path failure monitoring and tackling. The system comprises one SDN controller and multiple SDN switches. The SDN controller realizes real-time detection and cycle detection of each link in network topology, and monitors states of the SDN switches in real time and maintains the global network topology. The SDN controller comprises an OpenFlow module, an OpenFlow extension module, an event module, a topology module, a detection module and a topological service path calculating module. The detection module comprises a real-time detection module and a cycle detection module. With the system and the method, the whole network can be monitored, and network failure analyzing and tackling are realized.

Description

technical field [0001] The invention specifically relates to a system and method for fault monitoring and fault resolution of a service path, and belongs to the field of network fault analysis. Background technique [0002] Software Defined Networking (SDN, Software Defined Networking) is a new type of network architecture, which separates the control plane of the network from the actual physical topology, provides a programmable interface for the control plane, and hardware devices in the physical topology are no longer controlled by their own. Instead of controlling the routing of packets, the software receives forwarding rules from the control plane and forwards packets according to those rules. In this way, the network within a certain range (or SDN domain) is managed by a centralized and unified control logic unit, which solves the problem of scattered and independent operation and management of a large number of forwarding devices in the network, making the network Th...
