Embodiment Construction

[0022] Static link aggregation is a mode of Ethernet link aggregation. Between network devices configured with static link aggregation, multiple physical links are bundled together to form a logical link, and each physical link is used as a static link. The member links of the aggregation group can load share the traffic transmitted between network devices. The corresponding ports of all member links on the same network device are called member ports in the static aggregation group of the network device. For the member ports in the static aggregation group, the status of each member port can be determined according to the existing status determination process. The state includes selected state and unselected state. When the network device performs traffic forwarding through the static aggregation group, the traffic can be evenly distributed to the member ports in the selected state through HASH (hash) calculation. It can be seen that when the member ports on the network devic...

Abstract

The invention provides a traffic transmission control method and device. The method is applied to home terminal network equipment. A static link aggregation group including multiple member links is configured between the home terminal network equipment and opposite terminal network equipment. The method includes: for each member link, when a home terminal member port of the member link receives a link layer message sent from an opposite terminal member port, acquiring link aggregation state information carried in the link layer message; judging whether or not the state of the home terminal member port is consistent to that of the opposite terminal member port according to the link aggregation state information; if not, forbidding the home terminal member port to participate in traffic forwarding of the home terminal network equipment. By the method and device, under the condition that the two terminal member ports of each member link are inconsistent in state, load sharing of traffic through the member links is avoided, no loss of traffic in the static link aggregation group is ensured, and accordingly reliability in data transmission is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a flow transmission control method and device. Background technique [0002] The link aggregation technology can bundle multiple physical links between the local device and the peer device into one logical link, thereby increasing the link bandwidth. The logical link is called a link aggregation group, and each A physical link is called a member link of the link aggregation group. Multiple member links in the link aggregation group can load share the traffic transmitted between the local device and the peer device. [0003] In the existing link aggregation technology, the aggregation mode is divided into static link aggregation mode and dynamic link aggregation mode. In the static link aggregation mode, the status of member ports in the aggregation group is configured manually. When the selection status of a member port at one end of the member link changes...
