Abstract: This report describes the internal structure of the networking facilities developed for the 4.2BSD version of the UNIX operating system for the VAX. These facilities are based on several central abstractions which structure the external (user) view of network communication as well as the internal (system) implementation.
The report documents the internal structure of the networking system. The "4.2BSD System Manual" provides a description of the user interface to the networking facilities.
