Abstract

Problems caused by Internet Protocol datagram fragmentation are solved by creating a session context for the datagram fragments without actually reassembling the datagram from its fragments. The session context enables treatment of the datagram without actually reassembling it. Processing fragments can be followed by forwarding the processed fragments to another node that can further fragment the IP datagram.
