Abstract
In a hierarchical network, an aggregation parameter is exchanged between a node and its neighbor to agree on a negotiated parameter. A set of physical links between them are aggregated into a logical link according to the negotiated parameter and resource data of the logical link is stored in a database of each node. The resource data is then exchanged between them and the contents of the database of each node are updated with resource data of its neighbor. To optimize the link aggregation, an operating performance of the logical link is evaluated by the node using traffic data from the network, and the negotiated parameter is updated according to the detected operating performance. The updated aggregation parameter of the node is exchanged with its neighbor to agree on a negotiated updated parameter which is used to aggregate the physical links into the logical link.
