Problems solved by technology

However, because STP prevents loops by blocking certain ports, that is, multipath routing is not allowed, so all data packets are propagated on a tree (that is, data packets will be transmitted along a non-optimal path) , even if there is an idle link, it cannot be used, resulting in insufficient bandwidth utilization

Abstract

An embodiment of the present invention provides a data packet transmission method and an edge routing bridge device. The method includes: the first edge routing bridge device in the first area receives the message sent by the edge routing bridge device in the second area to the first edge routing bridge device. The first data packet of an area; the first edge routing bridge device determines the device identification group of the second area according to the first data packet; the first edge routing bridge device determines the device identification group according to the The first data packet determines the device identifier of the edge routing bridge device used to forward the backhaul data packet sent by the target device to the source device from the device identifier group in the second area; An edge routing bridge device sends the second data packet carrying the determined device identifier to the target device, wherein the determined device identifier is used as the source routing bridge of the second data packet Device identification, thus realizing load balancing by flow.

Description

technical field [0001] The embodiment of the present invention relates to communication technology, and in particular to a data packet transmission method and an edge routing bridge device. Background technique [0002] Span Tree Protocol (Span Tree Protocol, referred to as STP) is widely used in the data forwarding layer of Ethernet. STP is used as a network protection technology to generate a tree to avoid network loopback in the LAN and solve the problem of ring Ethernet. The "broadcast storm" problem of the network; wherein, STP is a data link layer (layer 2) communication protocol based on the Open System Interconnect Reference Model (OSI for short). However, because STP prevents loops by blocking certain ports, that is, multipath routing is not allowed, so all data packets are propagated on a tree (that is, data packets will be transmitted along a non-optimal path) , even if there is an idle link, it cannot be used, resulting in insufficient bandwidth utilization. ...
