Msocket: Multiple Stack Support for the Berkeley Socket API

Abstract

The de-facto standard for network programming, the Berkeley socket API, supports several protocol families. Unfortunately, it has a significant limitation in only allowing a single implementation for each supported protocol family. Hence, using Berkeley sockets, it is impossible to access multiple distinct networking stacks for the same protocol, e.g. multiple TCP/IP stacks. This paper defines, msocket, an extension to the Berkeley socket API which overcomes this limitation. msocket has been implemented as a feature of the View-OS project. Finally, we illustrate the utility and effectiveness of our extended API by providing some examples of its use.
