Abstract

Embodiments of the present invention provide a method for protecting a service path, a controller, a device and a system. The method comprises: an end node of a protection path receives a routing instruction transmitted by an SDN controller, the routing instruction including activation types of the service path and the protection path, forward relationships of the service path in the end node, and forward relationships of the protection path in the end node; the end node of the protection path activates at least one forward relationship in the forward relationships of the service path in the end node and the forward relationships of the protection path in the end node according to the activation types of the service path and the protection path; the end node of the protection path updates at one forward relationship in the forward relationships of the service path in the end node and the forward relationships of the protection path in the end node if it is determined that a fault occurs in the service path. The embodiments of the present invention solve the problem that in the SDN technology, the service path cannot be protected by the protection path when a fault occurs in the service path. The embodiments of the present invention relate to the technical field of communication.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method, controller, equipment and system for protecting a service path. Background technique [0002] Software Defined Networking (SDN, Software Defined Networking) is a new type of network architecture that separates the control plane of the network from the actual physical topology and provides programmable interfaces for the control plane. The hardware devices in the physical topology are no longer independent of each other. The software controls the routing of data packets, but receives the forwarding rules from the control plane and forwards the data packets according to these rules. In this way, in a certain range of networks (or SDN domains), a centralized and unified control logic unit manages the networks in the range, which solves the problem of a large number of forwarding devices in the network that are separated and independently operated and managed, mak...
