<p>Disclosed in the present invention are a method, device and system for bidirectional flow on the same path in an aggregation group. The method comprises: an endpoint of a link aggregation group (LAG) receives indication information from an opposite end in the link aggregation group, said indication information carrying the opposite end port serial number and/or flow distribution method; said endpoint, according to the indication information, determines its own port serial number and/or flow distribution method; said endpoint then distributes flow according to the determined port serial number and/or flow distribution method. The present invention solves a technical problem in the prior art, whereby port protection cannot be attained due to the inability to ensure that flows from a same service are transmitted on the same aggregation link, and effectively ensures that a same service on two ends of an aggregation group selects the same aggregation link bidirectionally, thus enabling protection of interconnect ports.</p> |
