This repository contains the formal specification of TCP, UDP, and the Sockets API developed in the Netsem project:
http://www.cl.cam.ac.uk/~pes20/Netsem/index.html
It has been relicensed under the simplified BSD license. Currently (2015), it is revived using contemporary systems (newer HOL4, PolyML, DTrace, ..)
The demo-traces/ directory contains some example traces (state is unclear)
The HOLDoc/ directory contains tools to typeset the specification (compiles and works).
The notes/ directory contains (meeting and other random) notes.
The specification/ directory contains the segment-level HOL4 specification (previously called Spec1).
The test/ directory contains the test generation and checking tools.
The unmaintained/ directory contains unmaintained specifications, the Lem port of the specifications, etc.
- Get PolyML (5.5.2 works fine)
- Get HOL (69fd18990913826ed08e76f768e703515de9c806 from 5th April 2017 works fine)
