Embodiment Construction

[0023] The embodiment of the present invention adopts the aggregation mechanism to construct the link of the Ethernet ring network, and the node determines the local aggregation group corresponding to the destination address according to the destination address in the information frame to be sent, while in the prior art, the port corresponding to the destination address is determined . An aggregation group can include one or more ports. When the link of one port in the aggregation group is interrupted, while other ports still have link connections, the corresponding link of the aggregation group is not interrupted. road transmission. However, in the prior art, if the link between any two ports is interrupted, the entire link will be interrupted. It can be seen that the embodiment of the present invention realizes the link transmission of the Ethernet ring network and reduces the probability of link interruption.

Abstract

The invention discloses a transmission control method and device in an Ethernet link, which are used for realizing Ethernet link transmission and reducing the possibility of link interrupt. The method comprises the following steps: a first node determines an aggregation group, corresponding to a destination address, of a local according to the destination address of an information frame to be transmitted; the first node selects a port with a link connection in the aggregation group; and the first node transmits the information frame through the selected port. The invention also discloses the device for realizing the method.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a transmission control method and device in an Ethernet link. Background technique [0002] Ethernet has developed into the most widely used LAN technology. Ethernet links include bus links, star topology links, and ring topology links. The ring topology is the most concise topology with redundancy, and has the advantages of simple and flexible control and saving the number of links. [0003] Taking 6 nodes as an example in the prior art, node 1 is connected to node 2, node 2 is connected to node 3, and so on, and finally node 6 is connected to node 1 to form a ring network link. The transmission process of the ring network link is: node 1 sends the broadcast message to node 6 through nodes 2-5, and node 6 sends the broadcast message to node 1. After node 1 receives the broadcast message sent by node 6, since the destination address in the broadcast message is a spec...
