Provision and customization of ATM virtual networks for supporting IP services

This paper addresses the provision and customization of virtual networks, and discusses how a virtual network can be programmed to support different approaches for integration of ATM and IP. First, the virtual network concept is introduced, followed by a discussion of a management system architecture for the control of the virtual network. Then, the paper discusses how a virtual network can be provided and customized through the partitioning of network resources and the programmability of the management system. This paper proceeds with a discussion of how the management system can support the integration of ATM and IP in order to demonstrate the capability of full customization of the network environment support. Finally, the partitioning of our NAL (Network Architecture Laboratory) testbed network is presented.
