Detection protocol extension method based on MPLSL2VPN service

Abstract

The invention provides a detection protocol extension method based on the MPLSL2VPN service. The method comprises the following steps: setting MPLS L2VPN point-to-point service, and binding a client side with a physical interface; setting a CFM non-client detection and client detection mode, namely a UP detection mode; and sending a CFM PDU. Compared with the prior art, the detection protocol extension method provide by the invention has the beneficial effects of solving the problem that the client side physical access in the L2VPN environment cannot do CFM detection, so that the operators have more choice to realize the client service demands.

Description

technical field [0001] The present invention is a detection protocol extension method based on MPLS L2VPN service, which is a kind of extension function based on MPLSL2VPN service pseudo wire level detection protocol. Line detection. Background technique [0002] With the operation of more and more types of services on the Internet, higher requirements are put forward for fault detection and management of carrier-class networks. Operators will require switching equipment provided by equipment manufacturers, and optical network equipment must support OAM functions. To ensure that Ethernet can also provide carrier-class requirements, including the ability to detect, restore and manage in time abnormal network errors or abnormal problems such as service degradation and failure. IEEE 802.1ag's CFM-Connectivity Fault Management is the basic protocol that provides these OAM capabilities. [0003] CFM: Using 802.1ag and Y.1731, this standard defines the active fault diagnosis pro...

Problems solved by technology

[0004] The current CFM client-to-client detection technology has problems in some MPLS L2VPN environments. For example, when the client accesses through a physical interface, the OAM detection of Ethernet services cannot detect services without VLANs.
