1 Introduction

This document presents a simple, special-purpose language called coNCePTuaL. coNCePTuaL is intended for rapidly generating programs that measure the performance and/or test the correctness of networks and network protocol layers. A few lines of coNCePTuaL code can produce programs that would take significantly more effort to write in a conventional programming language.

coNCePTuaL is not merely a language specification. The coNCePTuaL toolset includes a compiler, run-time library, and associated utility programs that enable users to analyze network behavior quickly, conveniently, and accurately.
