Abstract
Collisions caused by simultaneous allocation of the same channel identifier (CID) to two AAL2 connections over an ATM virtual channel connection between first and second nodes in an asynchronous network are avoided by the use of status records. Each node maintains a record of currently assigned CIDs and compares the CIDs of incoming connection requests with that record. Where the CID of such an incoming request is found to have been assigned, a message is returned to the request originator refusing the connection request. Preferably a set of CIDs is assigned to one node so that, in the event of a potential collision, that node seizes the connection.
