We present a novel approach to building and deploying network protocols The approach is based on mobile code demand loading and caching techniques The architec ture of our system allows new protocols to be dynamically deployed at both routers and end systems without the need for coordination and without unwanted interaction between co existing protocols In this paper we describe our architecture and its real ization in a prototype implementation To demonstrate how to exploit our architecture we present two simple protocols that operate within our prototype to introduce multicast and mobility services into a network that ini tially lacks them
