Next: Acknowledgements Up: Protocol Independence Using the Previous: State of Deployment


The existing BSD sockets API provides most of what is needed to write protocol- independent applications, but there are some things that needed to be added. More important is that the mechanisms for being abstract and generic be used correctly. It is not difficult to do, and the effort pays for itself in flexibility and future-proofing. It is hoped that authors of network programs will take the time to learn about protocol independence and work to use the technique in their programs.
