Embodiment Construction

[0118] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0119] The scheme of the present invention revolves around the first scheme of IEEE: to study the shortest path forwarding method of data in multiple spanning trees established by using the spanning tree protocol, and to study the data forwarding method with the ingress bridge as the root of the tree.

[0120] Option One:

[0121] Solution 1 is to establish a shortest path forwarding system rooted at the ingress in a bridged network, including the following:

[0122] In a bridged network, a tree is generated with each edge bridge as the root.

[0123] In addition to the external port of the bridge network, for other bridge ports, since the control protocol entity is responsible for establishing the forwarding path table, in order to avoid conflicts with the path forwarding table established by the original data packet source address lear...

Abstract

The method comprises: implementing a spanning tree by using each edge bridge as root; sending the registration packet to build the path forwarding table of each tree; the bridge ports except the external port of the bridge network close the packet source address learning process; when the packets from the outside of the bridge network arrive at the bridge network, using the entrance bridge where the packet arrives at is used as tree root to relay the packet in the bridge network, and the packet is sent out through the external port at the exit bridge.

Description

technical field [0001] The invention relates to the communication field, in particular to a data processing method in a bridge network and a bridge network. Background technique [0002] In a traditional network interconnected by Ethernet bridges, since the same tree is used for data forwarding in the same broadcast domain, it is generally impossible to guarantee that data packets are forwarded according to the shortest path, and it will cause data to be concentrated in some transmitted on the link. [0003] In order to enable the bridge to forward data according to the shortest path, the shortest path bridge project team of the International Standards Organization IEEE and the TRILL working group of the International Standards Organization are currently conducting research according to two ideas. [0004] The initial idea of ​​the IEEE shortest path bridge project team is: still use the spanning tree to forward all data packets, generate a tree with each bridge as the root...
