VIRTUAL PATH INTEGRATING METHOD USING MULTIPROTOCOL LABEL SWITCHING IN ATM SYSTEM

摘要

PURPOSE: A virtual path integrating method using a multiprotocol label switching in an ATM(Asynchronous Transfer Mode) system is provided for distributing and allocating a range of a virtual channel recognition value with respect to an input cell in accordance with the length of a label switching path and performing an accurate label mapping operation with respect to a next switching LSR or destination host of each cell without a cell interleaving. CONSTITUTION: A corresponding LSR of an LSR domain computes the length of an LSP(Label Switching Path) with respect to each interface(S210). At this time, the length may correspond to the number of nodes of each LSR of an LSR domain with respect to a path corresponding to each interface. In the corresponding LSR, an end terminal of the LSR domain may be an Egress node or a penultimate node which is a front end of the edge.
