Abstract: A method and apparatus for link aggregation in a data communications network. A dual-layer link aggregation is formed, including two peer nodes, each connected to at least a third node. The dual-layer link aggregation is formed of a peer link aggregation of ports for communicating with a peer node, distant link aggregation of ports for communicating with a third node, and an outer-layer link aggregation of the ports included in the peer link aggregation and the distant link aggregation. The third node may implement an inter-node link aggregation aggregating links to each of the peer nodes. Packets may be received and forwarded by the peer nodes in such a manner as to each link aggregation to be active simultaneously.
