Scalability Enhancements for Connection-Oriented Networks

By E. Gauthier and J.-Y. Le Boudec

Abstract

We consider the issue of increasing the number of connections that connection oriented networks, such as ATM, can handle. We describe one step that arises at reducing connection awareness inside the network. To that end, connections between the same pair of access nodes are grouped together and made indistinguishable inside the network. The concept of dynamic virtual path trunks is introduced as a support mechanism, and it is shown how virtual path links can be setup and maintained without additional round-trip delays. Keywords : connection awareness, multiplexed signaling, bandwidth re-negotiation. 1 Connection Limits for Network Nodes Support for real time traffic in communication networks requires that a connection oriented philosophy be employed. Some network technologies are connection oriented right from their definition : this is the case for ATM [1, 2], or Narrowband ISDN [3]. Some others initially based on connection-less principle, like bridged LANs or Internet [4], are int..
