Abstract

The invention relates to a detection protocol extension method based on MPLS L2VPN QINQ access service, which solves the problem that the client side QINQ access cannot perform CFM detection in the L2VPN environment, so that an operator can select more to realize the client service requirements. The method comprises the following steps: setting an MPLS L2VPN point-to-point service, and packaging the point-to-point service in a QINQ mode at a client side; Setting a CFM detection user side-to-user side detection mode, namely a UP detection mode; And sending the structure of the CFM PDU. According to the method, the QINQ service of the MPLS L2VPN is expanded mainly, and the defect that the QINQ service cannot perform link fault detection in a CFM UP mode is overcome; And the detectable service type range of the CFM detection protocol is expanded.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a detection protocol extension method based on MPLS L2VPN QINQ access service. 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 process on point-to-point and point-to-multipoin...
