Embodiment Construction

[0033] figure 1 It is a schematic diagram of the OAM physical link connection structure based on the PBN network, such as figure 1 As shown, a schematic diagram of the tunnel link connection structure of three switches is given: figure 1 The edge switches OAM-BEB1 and OAM-BEB2 are the edge devices of the carrier network, and the core switch BCB is the core device of the PBN network. BCB is just a representative of many core switches. Port A1 of the edge switch OAM-BEB1 is a loopback port, and port B1 Connect to the core switch BCB of the PBN network; port A2 of the edge switch OAM-BEB2 is a loopback port, and port B2 is connected to the core switch BCB of the PBN network.

[0034] The schematic diagram of OAM packets sent by the switch OAM-BEB1 based on the PBN network is as follows: figure 2 As shown, the OAM processor generates an OAM protocol message. According to the protocol type and matching rules, an outer layer VLAN is added to the protocol message, and the outgoing...

Abstract

The invention discloses a method and a system for realizing Operation and Maintenance (OAM) based on Packet Based Networks (PBN) network, wherein the method comprises the following steps that an OAM processor of a PBN network edge device produces protocol message and encapsulates an MIM outer head to the PBN network; (2), the network edge device receives data from the PBN network, removes the outer head of the MIM data and then sends the MIM data to a receiving module of the OAM processor to be processed; meanwhile, the invention discloses a system for realizing the system. The method and system disclosed by the invention can enable the devices located in different places of the PBN network edge to realize link fault diagnosis function, and can provide guarantee for the reliability when the user uses the operator bridging network.

Description

technical field [0001] The invention relates to the technical field of network communication, and relates to a method and system for realizing OAM based on a PBN network. Background technique [0002] MIM, that is, MAC-in-MAC, the carrier's backbone bridge protocol (that is, PBN), MIM is a two-layer virtual private network technology, which encapsulates the user's MAC in the carrier's In the MAC, it is isolated as the inner layer MAC, thereby enhancing the scalability of the Ethernet and the security of the business; it solves the limitation that the service provider only uses 4096 VLANs to share, and expands the MAC address space. [0003] OAM connection fault management provides end-to-end network monitoring and operation tools, which can perform tasks such as MAC Ping and L2 Trace Route in a large-scale L2 Ethernet, simplifying troubleshooting and monitoring of carrier-class Ethernet. At the same time, the CCM (Continuity Check Message) defined in the Ethernet OAM standa...
