METHODS TO ROUTE AND RE-ROUTE DATA IN OBS/LOBS AND OTHER BURST SWITCHED NETWORKS

摘要

In a LOBS network, packets (2,1,8,2,8,1), which in general refer to protocol data units (PDUs) such as IP packets, ATM cells SONET frames, Ethernet frames, or data from other application/transport layers, are assembled at the edge egress node into bursts. Only the packets going to the same egress node (where some of the packets may re-enter the LOBS network in order to reach their final destination egress node in a multi-hop fashion) can be possibly assembled into the same burst.
