Abstract
Introduction As network connectivity grows throughout the world, the uses of the network also grow. The current network infrastructure cannot and does not keep up with this increase in protocols. We believe that the "Active Networks" approach will help to deal with this problem. Active Networks are those networks in which a node of the network can undergo state changes and can provide information about its current state through execution of programs. Thus, it becomes possible to deploy a new protocol by loading it into a switch or for a packet to attempt to find an optimal route by discovering the state of the switch through which it is currently traveling. In the SwitchWare architecture for active networks, each node is capable of executing programs written in Caml, a dialect of ML. 1.1 Problem Statement We see several problems with existing networking technologies, specifically the Internet technology. First, as the Internet has moved from an experimental n
