Embodiment Construction

[0046] Technical idea of ​​the present invention is in:

[0047] 1. When the PE device supports the OAM mode of the segment, in order to transparently transmit the fault information of the segment to the terminal PE in an end-to-end OAM mode, the present invention first provides a new message type: FIN (Fault Information Notification , fault indication message) message, through which the fault information on the PW segment is transmitted to the MS-PW terminal PE.

[0048] 2. Based on the FIN message of the present invention, another solution of the present invention is based on the end-to-end (E2E) OAM mode. When a certain PW segment fails, the downstream PE (S-PE) can pass the FIN The message notifies the U-PE of the fault information on the PW in this segment, thereby triggering U-PE fast switching, alarm suppression, and alarm reporting.

[0049] 3. Based on the E2E OAM method described in the present invention, the present invention also provides an operation and maintena...

Abstract

A method for controlling detection and report as well as maintenance -consultation of fault at multijump pseudoline ( MP ) includes transmitting end to end monitoring message sent from source end node to terminal node by interchange node to realize end to end monitoring, sending fault notification message with fault information to downstream terminal node when fault is monitored by interchange node, carrying fault monitoring and reporting ability information in message being set up at course of setting up MP to let terminal enable to select maintenance manner in accordance with preset policy flexibly according to the last support ability.

Description

technical field [0001] The invention relates to a packet switching network, in particular to a fault detection, reporting and maintenance negotiation control method of a multi-hop pseudowire. Background technique [0002] PSN (Packet Switch Network, packet switched network) is a development trend of the current transport network convergence, that is, traditional services are migrated to the converged network, and the converged network must be able to meet the needs of new service development. The PSN network has received considerable attention due to its high bandwidth utilization (statistical multiplexing) and the gradual improvement of its QOS guarantee capability. (Asynchronous Transfer Mode, Asynchronous Transfer Mode) Private line services are migrated to the PSN to reduce operating costs and improve service deployment capabilities. PSN networks mainly include MPLS (Multiple Protocol Label Switching) networks, L2TP (Layer 2 Tunneling Protocol, Layer 2 Tunneling Protoco...
