example 1

[0053] Example 1: If the local state is in the state of failure (operational down), no matter what the state of the opposite end is, the PW is in the state of fault (fault), as in case 1 above;

example 2

[0054] Example 2: If the local status is active (active), if the peer status is received as active, then the PW status is active, as in case 2 above; if the peer status is received as standby, the PW The state is the receiving state, as in the above case three;.

example 3

[0055] Example 3: If the local status is standby, and if the peer status is received as active, the PW status is forwarding, as in case 4 above; if the peer status is received as standby, the PW status is resting State, such as the above-mentioned case five.

Abstract

The embodiment of the invention relates to a method, a device and a system for processing traffic flow based on pseudowires. The method for processing traffic flow based on pseudowire comprises the following steps of: receiving traffic flow from user edge devices; determining a pseudowire aggregated set corresponding to the traffic flow; and based on the local policy, transmitting the traffic flow to an opposite device through the pseudowires which is in the sending state or the moving state in the pseudowire aggregated set. The pseudowire aggregated set comprises more than one pseudowires corresponding to the traffic flow. Based on the local policy, the local device in the embodiment of the invention transmits the traffic flow to the opposite device through the corresponding pseudowires which are in the sending state or the moving state in the pseudowire aggregated set, enhancing the average convergence speed of the traffic flow and shortening the switching time during network failure.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a pseudowire-based service flow processing method, device, and system. Background technique [0002] End-to-end pseudowire emulation (Pseudo Wire Emulation Edge-to-Edge; abbreviation: PWE3) is a kind of emulation such as asynchronous transport mode (Asynchronous Transport Mode; abbreviation: ATM) on a packet switching network (Packet Switch Network; abbreviation: PSN) ), frame relay (Frame Relay; FR for short), Ethernet (Ethernet) and other key attribute mechanisms of services. PWE3 can enable operators to migrate traditional services to PSN to reduce network operating costs (Operating Expense; OPEX for short). [0003] In order to ensure high availability of services, different layers of the network need to support redundancy. If resources such as network nodes, links, and channels in use fail, they can be switched to other redundant availab...
