A design and implementation of ASN.1 parser for H.323 protocol stack

Abstract

This paper presents an object oriented implementation of library for generation and parsing of messages in H.323 protocol stack. Design decisions and rationale behind them are discussed. UML diagrams of important aspects of software are provided. The library is implemented in C++ programming language. Several metrics of the software are presented, and discussed. Implementation included a significant effort in the testing phase. Automated testing using CPPUnit was conducted, and an overview of activities in this phase is given too. The library has performed well in all of the tests, and is ready for use in development of H.323 based applications. ©2007 IEEE.
