Abstract
A packet switching node is coupled by links to other nodes of a network, and receives and assembles packets belonging to a specified packet flow, into bursts of packets with a burst control packet indicating a sequence of the burst in the flow. The node determines whether to distribute the flow across several links. If so, the bursts are then forwarded for switching to the output ports of the selected links. Distributing the flow over multiple links can enable more flexible and efficient filling of allocated bandwidth on links, as traffic increases. To reduce the risk of losing the order of packets the sequence of the bursts is indicated for use in reordering at intermediate nodes during transmission through the network.
