Computer- Communication Networks presents a collection of articles the focus of which is on the field of modeling, analysis, design, and performance optimization. It discusses the problem of modeling the performance of local area networks under file transfer. It addresses the design of multi-hop, mobile-user radio networks. Some of the topics covered in the book are the distributed packet switching queuing network design, some investigations on communication switching techniques in computer networks and the minimum hop flow assignment and routing subject to an average message delay constraints. The analysis of the multi-access communication channel is covered. The local area network file transfers are discussed. The text describes the C-PODA protocol. The congestion control scheme for window flow controlled computer network is presented. A chapter of the volume is devoted to the description of a fairness control algorithm. Another section of the book focuses on the analysis of hierarchical model. The book will provide useful information to computer programmers, network analysts, students, and researchers.
