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 present invention provides a traffic transmission control method and device. The method is applied to a local network device. A static link aggregation group including multiple member links is configured between the local network device and the peer network device. The method includes: For each member link, when the local member port of the member link receives the link layer packet sent by the peer member port, it obtains the link aggregation status information carried in the link layer packet; according to the link aggregation The state information judges whether the state of the member port of the local end is consistent with that of the member port of the opposite end; if they are inconsistent, the member port of the local end is prohibited from participating in the traffic forwarding of the local network device. By applying the embodiment of the present invention, it is possible to prevent the load sharing of traffic through the member link when the status of the member ports at both ends of the member link is inconsistent, so as to ensure that the traffic in the static link aggregation group will not be lost, thereby improving the Reliability of data transmission.

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...
