Networking Services QoS, Signaling, Processes Harry Perros The book has been structured around the Next Generation Network (NGN) framework, which separates the transport network, services, and signaling protocols into the service stratum and the transport stratum. The service stratum is the control plane for the establishment of networking sessions, and the transport stratum is the data plane over which the data of a networking service is transported. Within this context, the author explains in detail the signaling protocols used in the service stratum for setting up networking services, and the Quality of Service (QoS) architectures used in the transport network to guarantee QoS. Networking Services: -Provides a systematic coverage of the signaling and QoS architectures for networking services. -Explains topics such as SIP, IMS, MPLS, DiffServ, LDP, RSVP-TE, congestion control, RACF, and VPNs. -Describes IMS-based architectures for popular networking services such as VoIP, presence, instant messaging, video conferencing, multimedia telephony, IPTV, and service and device continuity. -Describes queueing theory and simulation techniques used to dimension the capacity of a networking service. -Illustrates the material with problems and projects Networking Service is a textbook for graduate and senior undergraduate students in computer science and computer engineering, and also a reference book for networking engineers.
Harry G. Perros is a Professor of Computer Science at NC State University, an Alumni Distinguished Graduate Professor, and a Fellow of IEEE. He is also the Program Coordinator of the Master of Science degree in Computer Networks at NC State University. He received the B.Sc. degree in Mathematics in 1970 from Athens University, Greece, the M.Sc. degree in Operational Research with Computing from Leeds University, England, in 1971, and the Ph.D. degree in Operations Research from Trinity College Dublin, Ireland, in 1975. He has held visiting faculty positions at INRIA, Rocquencourt, France, NORTEL, Research Triangle Park, North Carolina, University of Paris 6, France, Victoria University, New Zealand, and Beijing University of Post and Telecommunications., Beijing, China. He has published over 200 papers in the area of performance modeling of computer and communication systems, and he has organized several national and international conferences. He has also published three print books (Queueing Networks with Blocking: Exact and Approximate Solutions, Oxford Press 1994, An Introduction to ATM Networks, Wiley 2001, and Connection-Oriented Networks: SONET/SDH, ATM, MPLS, and Optical Networks, Wiley, 2005), and an e-book (Computer Simulation Techniques - The Definitive Introduction, 2009) that can be download from his web site free of charge. In 1995, he founded the IFIP Working Group 6.3 on the Performance of Communication Systems, and he was the chairman from 1995 to 2002. He is currently an associate Editor of several Journals including the Performance Evaluation Journal, and the Telecommunications Systems Journal. His current research interests are in the area of networking services, QoS, and queueing theory. In his free time he likes to play the bouzouki and also go sailing on his beloved Aegean, a Pearson 31.
