Abstract
An apparatus and a method for transferring a packet flow having a plurality of packets in a communication network which includes plural subnetworks, first and second end systems connected to the respective subnetworks and a transit system for relaying the packet and a message between the first and second end systems through a default route, where the packet flow is forwarded from the first end system to the second end system or to a terminal connected to the second end system, in the first end system, determines it by collating the packet with a predetermined criterion whether to forward the packet flow through a shortcut path bypassing the default route and in dependence upon the determining, sends to the second end system through the default route, a request message requesting to set the shortcut path, along with an address of the first end system; in the second end system, requests the communication network to set the shortcut path between the first and second end systems in accordance with the request message; and in the first and second end systems, forwards the packet flow through the shortcut path.
