Ethernet ring protection switching method for hybrid network

Abstract

The invention relates to an Ethernet ring protection switching method for a hybrid network. The method comprises the following steps: 1, establishing an Ethernet ring protection instance based on a virtual private network (VPN); and 2, controlling the mapping from VPN service to the Ethernet ring protection instance, wherein step 1 comprises the following concrete steps: 1.1, establishing the VPN service; 1.2, judging whether the established VPN service is Ethernet ring service of the control type, if not, not carrying out processing, and otherwise, establishing the Ethernet protection instance (including adding the configuration information of the Ethernet protection instance, establishing a ring port of the Ethernet ring instance, and establishing the mapping from a VPN service group to the instance; and 1.3, judging whether the configuration information of the Ethernet protection instance is successfully added, judging whether the ring port of the Ethernet ring instance is successfully established, and judging whether the established VPN service group is successfully mapped to the instance, if yes, judging that the Ethernet ring protection instance based on the VPN is successfully established.

Description

technical field [0001] The invention relates to a method for protecting and switching an Ethernet ring network in a hybrid network. More specifically, in the method, the concepts of controlling virtual private network services, multiple instances, logical topology and dedicated control tunnels are introduced. Background technique [0002] The existing hybrid Ethernet ring network protection switching methods are mainly as follows: [0003] 1. Based on physical topology - protection switching for physical ring topology; [0004] 2. Based on the physical port - perform protection switching on the physical port; [0005] 3. Single instance - a physical port can only be on one ring instance; [0006] 4. Bridge Protocol Data Unit Tunneling (BPDU Tunneling) transparently transmits protocol control packets. [0007] There are following shortcoming respectively in above-mentioned existing method: [0008] 1. For the physical topology, it cannot provide the protection of the logi...

Problems solved by technology

[0005] 3. Single instance - a physical port can only be on one ring instance;

[0008] 1. For the physical topology, it cannot provide the protection of the logical topology of the virtual private network service;

[0009] 2. For physical ports, it cannot provide protection for logical ports in virtual private network services;

[0010] 3. A single instance cannot provide protection for different virtual private network service groups;

[0011] 4. Bridge Protocol Data Unit Tunneling (BPDU Tunneling) transparently transmits protocol control packets, and the edge nodes of the hybrid network do not participate in ring network protection switching, resulting in long-term service interruption when protection switching occurs
