Abstract

The embodiment of the present invention provides a service path protection method, controller, device, and system. The end node of the protection path receives the routing instruction sent by the SDN controller. The routing instruction includes the activation type of the service path and the protection path, and the service path. The forwarding relationship in the end node and the forwarding relationship of the protection path in the end node; the end node of the protection path activates the forwarding relationship of the service path in the end node according to the service path and the activation type of the protection path, and the protection path in the end node At least one of the forwarding relationships in the internal forwarding relationship; when it is determined that the service path fails, the end node of the protection path updates the forwarding relationship of the service path in the end node, and at least one of the forwarding relationship of the protection path in the end node Forward relationship. The embodiment of the present invention solves the problem that in the SDN technology, when the service path fails, the protection path cannot be used to protect the service path. 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 service path protection method, controller, equipment and system. 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 a programmable interface for the control plane. The 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 The design, depl...
