Summary :

This paper describes key technologies for implementing ATM internode signalling. The reliability of a multimedia handling network can be improved by setting multiple virtual paths(VPs)between two nodes and setting signalling links over each internode VP. A software structure appropriate for handling the signalling protocol(MTP3b)within this framework is proposed. We also propose a cost-effective and reliable way to set a signalling route between a node and the service control point(SCP), based on the associate mode structure. Evaluation by implementing a node system shows that it requires only 15% more dynamic program steps for one sending/receiving sequence of the VP signalling than the existing method for circuit-related information. Thus, we could attain highly reliable and cost-effective signalling for ATM multimedia networks.
