Method and device for flow balance of aggregation port, aggregation port and network equipment

Abstract

The invention discloses a method and device for the flow balance of an aggregation port, the aggregation port and network equipment. The method comprises the steps of: selecting a flow balance policy in which the flow difference among member ports in a unit time is minimum as the flow balance policy used by the aggregation port; in the unit time, periodically judging whether the flow difference among the member ports is increased and the change amplitude exceeds a set range or not when the aggregation port uses the selected flow balance policy; if the flow difference among the member ports is increased and the change amplitude exceeds the set range, re-determining the flow balance policy in which the flow difference among the member ports in the unit time is the minimum as the flow balance policy currently used by the aggregation port; or else, remaining the current flow balance policy of the aggregation port unchanged. Through the invention, the configuration of the optimal flow balance policy can be automatically realized; when the flow difference among the member ports changes, the flow balance policy is adjusted in real time to obtain the optimal flow balance policy after the flow changes and ensure that the flow balance policy can play a real role in the flow balance along with the flow change of the aggregation port.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method, device, aggregation port and network equipment for traffic balance of an aggregation port. Background technique [0002] Port aggregation refers to the aggregation of multiple ports together to form a virtual aggregation port, so as to realize the sharing of inbound / outbound load among the member ports in the aggregation port, and also provide higher connection reliability. The formed aggregation port is usually called an aggregate port (Aggregate Port), and the members forming the aggregate port are called aggregate member ports. [0003] Compared with ordinary ports, the biggest advantage of port aggregation is that it can provide greater bandwidth, such as figure 1 As shown, there are 8 100M ports on device A and 8 100M ports on device B. Each connection can logically provide only one 100M bandwidth. If the 8 ports of device A form an aggregation port, and the ...
