Part 1: What is SDL Diagram?

Specification and Description Language (SDL) is a computer-science language used to describe the behaviour and reactions of a system’s components. Its ability to process multiple applications real-time make it a popular language within, and indeed outside, the telecommunications industry.

SDL gives users an overview of a complex system. It's key strength lies in its ability to illustrate and describe the structure and behaviour of communication systems in real-time. Additionally, its notation is easy to understand, and is an incredibly accurate language, meaning less ambiguities and inconsistencies are found.

Transition Diagram of SDL

A transition diagram of SDL suitable for performance evaluation and validation is presented. The modifications are done so that the Transition diagram of SDL is very close to SDL. The differential equations of a TDSL are formed to deliver the steady-state availability of the machine.
