Prototyping Virtual Network Service


Virtual Network Service (VNS) is a value-added network service for deploying virtual networks in a managed wide area IP network. Using a common network infrastructure, a virtual network service provider can provide intranet services to multiple organizations that want to connect geographically distributed sites.

We believe that a virtual private network (VPN) created by VNS must receive a service level comparable to implementing it with physical leased lines and dedicated circuits. In this respect, a VPN must receive secure data transport, bandwidth guarantees and opaque (self-contained) transport of data. As a service, configuration and resource management must be tractable and customizable on a per VPN basis. Research issues pertinent and must be considered in developing such a service include the control architecture, the data path, routing and forwarding, VPN membership dissemination and security. In this presentation, we will describe our approach to designing and implementing a prototype of such a service.
