Abstract (en)
[origin: WO03034670A1] A method and apparatus for transferring data packets over a router (100) comprising interface units (106) and a switchingunit (108). It is determined whether a received data packetbelongs to an existing session context by comparing extractedheader information with any session contexts stored in the router. In that case, a header translation is applied for thepacket according to the existing session context duringtransfer through the router from an ingress unit to an egress unit. Otherwise, a new session context is createdincluding selecting a header translation scheme to be used for further packets of the new session. The new session context is stored in the router together with a context IDassigned to the new session context. In this way, processingwork and delays are reduced in the router when transferring data packets, thereby enabling a high data throughput.
