A network emulation tool

The Network Emulation Tool (NET) is a software simulation of a computer network. NET is designed for research and teaching of distributed algorithms in a computing environment that supports the Berkeley Unix operating system. Two methods are provided for customizing NET to simulate a particular computer network. One can specify the parameters of a standard network provided by NET, or one can program a new communication layer. This report describes the NET interfaces and gives examples of the use of the NET system.
