AI Technical Summary

Problems solved by technology

In the process of realizing data packet forwarding, the inventors found that when the link between the main router and TMG fails, the ETH-Trunk member interface on the main router cannot send the traffic to the standby router in time, resulting in too long transmission delay and lower quality issues

Abstract

The embodiment of the invention discloses a data packet transmitting method, a device and a system belonging to the communication field and solving the problem that a data packet originally located ina member interface in an opening state can not be transmitted to a standby router in time when a member interface switch occurs on a primary router in the prior art. The data packet transmitting method comprises the following steps: obtaining the using state of a virtual local area network member interface of the primary router, wherein the using state comprises an opening state and a closing state; obtaining the address analysis protocol item of an Ethernet relay member interface of the primary router when the virtual local area network member interface of the primary router is in the opening state; and transferring the data packet in the virtual local area network member interface of the primary router through the standby router according to the address analysis protocol item of the Ethernet relay member interface of the primary router. The technical scheme provided in the embodiment of the invention can be applied to transmitting data packets.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data packet sending method, device and system. Background technique [0002] In a virtual local area network (Virtual Local Area Network, VLAN), a trunk media gateway (TrunkMedia Gateway, TMG) ​​receives a data packet sent by an IP bearer network through a virtual local area network interface (Virtual Local Area Network Interface, VlanIF) in a router. In order to ensure the reliability of transmission, at least two routers are set between the VLAN and the IP bearer network, and the VlanIF interface of the router includes at least two member interfaces, including the VlanIF member interface for establishing communication with TMG and the VlanIF member interface for communicating with neighbors. The router establishes a communication Ethernet trunk (Ethernet Trunk, ETH-Trunk) member interface. When the link between the main router and TMG fails, the main router sends traffic to...
