Embodiment Construction

[0027] In practical applications, PW failures are basically caused by the failure of equipment at one end, such as the power failure of PE at one end; this means that a failure of a certain PW is often accompanied by Faults of other PWs. In other words, when one of the two PE devices originally connected through the PW fails, the tunnel between the two devices will lose connectivity, and the route between the two devices will be unreachable. If all the PWs carried by it are detected , will feed back the fault detection results. Therefore, if the detection of each PW is skipped, and the tunnel carrying the PW or the route of the carrying tunnel is directly detected, the detection result can be guaranteed, and unnecessary repeated detection of multiple PWs in the same tunnel can be avoided. Based on this idea, the present invention provides a technical solution for detecting and processing PW faults.

[0028] First, the present invention provides a method for detecting and pro...

Abstract

The invention discloses a PW fault detection treatment method and a component, which is applicable to PW detection treatment between UPE and NPE respectively and includes the connectivity detection of the tunnel or route between the UPE and the NPE, detection of connectivity fault situation, PW batch switch treatment toward PW between the UPE and the NPE; and detection treatment applicable to PW between PE, including the connectivity detection of the runnel or route between PE and PW batch between PE marked as fault PW for the detection of connectivity fault situation. The method and the component disclosed by the invention simplify PW fault detection and treatment complexity and improve the stability and treatment efficiency of the network.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a detection and processing method and components of a virtual link (Pseudo Wire, PW for short) fault. Background technique [0002] Virtual Private LAN Services (VPLS for short) is an increasingly mature Layer 2 virtual private network (Virtual Private Network, VPN for short) technology. A fully connected PW is established between provider edge devices (Provider Edge, referred to as PE, also known as packet switching network edge devices) to virtually connect geographically dispersed CEs; as shown in Figure 1, it is a VPLS network Schematic diagram: Users connect to PE1, PE2, and PE3 from their respective LANs through Customer Edge (CE) 1, 2, and 3, so that geographically dispersed points can simultaneously access a network operated by a service provider. Packet-switching network: when the same VSI is configured on these PEs, it can provide virtual switch functions for the ...
