Abstract

The per-node delay for transfer of a datagram that is segmented into datagram segments is reduced by a header compression based segmentation and link layer switching. For each datagram segment, the segmentation header includes a unique segmentation context identifier (CID). Based on the segmentation CID, the datagram segments are forwarded between intervening nodes of source and destination, without being reassembled at each node. The segmented data gram is reassembled at the destination node based on sequence numbers assigned to the datagram segments during segmentation.
