METHOD FOR ASSIGNING CHANNEL IDENTIFIER FOR CONNECTION BETWEEN NODES IN ATM NETWORK APPLYING ATM ADAPTATION LAYER TYPE 2

摘要

PURPOSE: A method for assigning a channel identifier for a connection between nodes in an ATM network applying ATM adaptation layer type 2 is provided to easily and efficiently perform an assignment of a CID(channel identifier) by performing the assignment using a CCST(CID connection status table). CONSTITUTION: A plurality of VPs(virtual paths), a plurality of VCs(virtual channels) corresponding to each VP, and a plurality of CID information corresponding to each VC are stored according to a number sequence in CCSTs, In the case of generating a call request, an ATM layer of a departure place node(100) and an ATM layer of an intermediate node(200) assign a VC 1 with reference to CCSTs(14,24) and assign a CID(channel identifier) 10 included in the VC 1. An ATM layer of the intermediate node(200) and an ATM layer of a destination node(300) assign a VC 2 with reference to CCSTs(24, 34) and assign a CID 20 included in the VC 2.
