摘要

The method involves emitting a packet (41) with a virtual channel and a virtual path for use on a private network. The virtual channel consists of 12 bits with the four msb having a predetermined value. The virtual path contains 16 bits with the eight msb storing self-routing data. The packet is channelled (42) to a node connected with the PTN. The private virtual path is shifted to a reserved zone within the header and replaced (43) by a public virtual path. The packet is then routed (44) through the PTN to be received at another node of the private network. The public virtual path is replaced (45) by a stored private virtual path from the zone prior to routing (46) to its destination.
