The evolving nature of complex traffic issues of IP (Internet Protocol)-based Telecollaboration (TC) business system technology requires an intuitive understanding for the participants not just to make sense of design issues involved but also to provide an insight of guaranteed run time performance. The aim of this study is to introduce new theoretical underpinnings for modeling of VoIP (Voice over IP) applications, which may have impact on conventional wisdom of TC in context of often contradictive aspects of user Quality of Experience (QoE). In this paper, we also focus on the performance evaluation and traffic control factors as they present an objective engineering challenge for development of analytic traffic models. Close attention is paid to performance issues such as packet loss probability, packet delay and jitter apart. This research paper concludes on highlighting the importance of mathematically formal dimensioning and evaluation of IP networks for an improved user percept...
