Embodiment 1

[0042]An embodiment of the present invention provides a fault handling method for a virtual private local area network. When the relay virtual switching instance detects a pseudowire failure between the relay virtual switching instance and the local backbone network component virtual switching instance, or when the When the relay virtual switching instance learns that the connection between the virtual switching instance of the local service instance component and the customer edge router is faulty, if figure 1 As shown, the method includes:

[0043] Step S101, the relay virtual switch instance sends a fault notification message to the peer backbone network component virtual switch instance, and the fault notification message carries the local service instance component virtual switch instance and the peer service instance component virtual switch instance Exchange instance common business instance tags;

[0044] In the embodiment of the present invention, the fault notificat...

Embodiment 2

[0055] An embodiment of the present invention provides a fault handling method for a virtual private local area network. When the relay virtual switching instance detects a pseudowire fault between the trunk virtual switching instance and the local backbone network component virtual switching instance, as Figure 4 As shown, this method includes:

[0056] Step S401, the relay virtual switch instance sends a fault notification message to the peer backbone network component virtual switch instance, and the fault notification message carries the local service instance component virtual switch instance and the peer service instance component virtual switch instance Exchange instance common business instance tags;

[0057] In the embodiment of the present invention, the fault notification message may be signaling in the form of a label distribution protocol. Generally speaking, the fault notification message carries a plurality of fields respectively indicating service instance lab...

Embodiment 3

[0094] The embodiment of the present invention provides a fault handling method of virtual private area network, such as image 3 Shown is the specific situation of the embodiment of the present invention.

[0095] exist image 3 , if the connection between the virtual switching instance of the local service instance component and the user edge router fails, then, as Figure 8 As shown, this method includes:

[0096] Step S801, the virtual switching instance of the backbone network component at the local end learns that the virtual switching instance of the service instance component at the local end has a connection failure with the customer edge router;

[0097] When the connection between the user edge router and the virtual switch instance of the local service instance component fails, the local service instance component virtual switch instance can perceive that it cannot communicate with the user edge router, and the local service instance component virtual switch inst...

Abstract

The embodiment of the invention discloses a fault processing method, a device and a system for a virtual private local area network, relates to the technical field of network communication, in order to solve the problem of bandwidth waste of a VPLS (Virtual Private Local Area Network Service) network, caused by that the CE connected at the other end of the IVSI still transmits data to the VPLS network when a CE (Customer Edge) connected at one end of an IVSI (Instance Component Virtual Private Instance) can not access to a network. The fault processing method comprises the following steps: a relay virtual private instance sends fault notice information to a backbone component virtual private instance at an opposite terminal, wherein the fault notice information carries the instance component virtual private instance at a home terminal and an instance tag shared with the instance component virtual private instance at the opposite terminal; and the backbone component virtual private instance at the opposite terminal receives the fault notice information, and the instance component virtual private instance at the opposite terminal is closed according to the instance tag carried by the fault notice information.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a virtual private local area network fault handling method, device and system. Background technique [0002] A virtual private network (Virtual Private Network, referred to as VPN) refers to the technology of establishing a private network on a public network. The reason why it is called a virtual private network is mainly because the connection between any two nodes of the entire VPN network does not have the end-to-end physical link required by the traditional private network, but the architecture is provided by the public network service provider. Logical network on the network platform, user data is transmitted in the logical link. [0003] Among them, a virtual private local area network service (Virtual Private Local Area Network Service, VPLS for short) is a typical layer 2 virtual private network technology. Its core idea is to use the signaling protocol t...
