Abstract

In a connection-oriented network, a normal signaling packet is sent from a source user to the network. A first virtual path identifier (VPI) is determined at a first node of the network according to a destination address in the packet, and the first VPI is inserted into the packet, and forwarded to the second node, where it determines a second VPI
according to the packet's destination address, adds the second VPI to the first VPI in the packet to produce a source route, and forwards the normal signalling packet to a destination user. The destination user returns an acknowledgment (ACK) packet to the source user, containing the source route. In response ko the ACK, the source user stores the source route contained in the packet into a source route table, and selects an initial VPI
and an initial virtual channel identifier (VCI) from a copy of network resource, and sends a fast signaling packet, captaining the source route, the initial VPI and VCI. At the first node, a first VCI is selected according to the first VPI in the source route of the fast signaling packet, the initial VPI/VCI in the packet are mapped to the first VPI/VCI, and the initial VCI in the packet is overwritten with the first VCI, and the packet is forwarded to the second network node, where a second VCI is selected according to the second VPI in the source route of the packet, and the first VPI/VCI in the packet are mapped to the second VPI/VCI, and the first VCI in the packet is overwritten with the second VCI, and the packet is forwarded to the destination user.
