Chapter 17: Evaluating VoIP Technology Balancing Technology Push and Market Pull
A J Heron and A H Warren
17.1 Introduction
VoIP is a maturing, yet still emerging, technology, and its products are therefore both relatively new in the market-place and continually evolving. Such a rapidly changing technological environment for service providers, equipment manufacturers and end users is compounded by continually developing regulatory policy. Any potential purchaser of a new technology therefore has the dilemma that equipment may become rapidly dated by new developments or lack of features subsequently identified as essential requirements for commercial applications. As a consequence, establishing the precise capabilities of specific offerings at a given point in time is essential for anyone with a serious interest in the VoIP industry. This chapter describes an approach to evaluating VoIP solutions, the problems associated with the testing of VoIP networks and components, and the tools and techniques employed to do so. It outlines the capabilities of the VoIP technology evaluation test bed, which is administered by BTexact Technologies at Adastral Park, and includes some typical results obtained using perceptual analysis measurement and IP network simulation technologies to assess voice quality.
17.2 Evaluation Stakeholders
There are a number of major stakeholders in the VoIP industry, as discussed in Chapter 1. Each of these groups reflects a specific interest in what the technology currently offers and what it may offer in the future. Exploring the capabilities a particular product offers and predicting what it may be possible to deliver in the future falls within the realm of technology evaluation and assessment. While...
