Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] see figure 1 , figure 1 It is a flow chart of the PTN network failover method, and the PTN network failover method includes the following steps:

[0023] S101. Receive a first client signal invalidation message sent by a remote device, wherein the first client signal invalidation message is a message carrying a closed flag generated when a user-side port connection of the remote device is in a closed state.

[0024] Wherein, the local device and the remote device may be aggregation layer devices and / or access layer devices, the local device refers to the device currently processing informa...

Abstract

The invention relates to a PTN (Packet Transport Network) failover method and system, wherein the method comprises the steps of: receiving a first client signal fail message sent by remote equipment,wherein the first client signal fail message is a message carrying a shutdown mark and generated when connection of the user network interface of the remote equipment is in a shutdown state; analyzingthe first client signal fail message, and, if the fact that the first client signal fail message carries the shutdown mark is obtained by analysis, shutting down the user network interface of local equipment after a first set time interval; and, setting the state of a failover set of the local equipment to a failover state, setting a fault source to a maintenance association end point-maintenanceassociation fault source, and setting a fault type to a client signal fail fault. By means of the method, if the fact that the first client signal fail message carries the shutdown mark is obtained by analysis, the user network interface of the local equipment is shut down after the first set time interval; and thus, electricity consumption when a PTN system fails can be reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a PTN network failover method and system. Background technique [0002] Packet Transport Network (PTN) based on packet switching adopts Multi-Protocol Label Switching (MPLS-TP) in the transport network as the main technology of the network, which follows the end-to-end The pseudowire emulation (Pseudo Wire Emulation Edge-to-Edge, PWE3 for short) framework carries packet services through a tunnel (Tunnel) and a pseudowire (Pseudo Wire, PW for short). [0003] Since the Multi-Protocol Label Switching (MPLS) technology supports multi-layer labels and the connection-oriented characteristics of the forwarding plane, and has good scalability, it can be used on a virtual private network (Virtual Private Network, VPN for short). Widely used, it can ensure the quality of service (Quality of Service, referred to as QoS) and security, and has traffic engineering capabilities...
