The problem is that transmission control protocol (TCP) and Internet protocol (IP), which support the most popular Internet applications, were not developed for real-time data applications and has no quality- of-service guarantees for running in that mode; the asynchronous transfer mode (ATM), which does have those features, is very expensive, so many networks run it only as a lower layer technology at the core, with TCP/IP at the edge. Hassan (computer science and software engineering, Monash U., Australia) and Atiquzzaman (electrical and computer engineering, U. of Dayton, Ohio) compile research on the performance dynamics of such systems from the various conference proceedings, journals, and standards documents, and explain some of the issues they reveal. Some background in computer networks is necessary to understand the treatment, but no prior knowledge of the protocols or the mode. Annotation c. Book News, Inc., Portland, OR (booknews.com)
