Abstract:
1. A method for reducing service impairment in a Link Aggregation Group (LAG) comprising: dividing a service packet into multiple service sub-flows; allocating the multiple service sub-flows to each physical port of a plurality of physical ports such that a maximum difference between a quantity of service sub-flows on one physical port and a quantity of service sub-flows on another physical port is equal to 1; determining a first group and a second group from the plurality of physical ports, wherein physical ports of the first group have a same number of service sub-flows and physical ports of the second group have a same number of service sub-flows, and the number of service sub-flows on each physical port of the first group is larger than the number of service sub-flows on each physical port of the second group by 1; adding a new physical port; selecting one physical port from the first group consecutively; obtaining one service sub-flow on the selected physical port and allocating the obtained one service sub-flow to the new physical port; and determining whether a difference between a quantity of service sub-flows on the new physical port and a quantity of service sub-flows on each of the physical ports is equal to or less than 1; forwarding the service packet, according to the corresponding physical ports of the service sub-flows.
