ABSTRACT:
Load balanced transport of best efforts traffic together with delay-bounded traffic over a multilink bundle combines fragmentation and fragment distribution for best efforts packets with per-flow balancing for delay-bounded traffic. In the preferred embodiments, the best efforts packets receive Multilink Protocol treatment, including fragmentation and addition of sequence headers. Fragments of packets for one such communication go over the various links within the bundle, as appropriate for load balancing on the links. For each delay-bounded flow, such as for a VOIP service, the sending node hashes the packet header data and applies all packets for the flow to one of the links, assigned as a function of the hash value. Different flow headers produce different hash results; therefore the node sends different flows over the different links in a substantially balanced manner.
