Abstract
The header of each packet contains a virtual channel identifier. The virtual path identifier is a packet distribution agent enabling a packet to be distributed when the packet is travelling over a public network, and the virtual path identifier is a packet-routing agent enabling the packet to be routed when said packet is travelling over a private network. Each time a packet is transferred from a private network to a public network, routing data contained in the virtual path identifier is shifted to a reserved portion of a virtual channel identifier that is also contained by the packet, and it is replaced by distribution control data. Each time a packet is transferred in the opposite direction, the distribution control data in the packet is replaced by private network internal routing data.
