Perros Releases Book on Signaling Protocols
Congratulations to Dr. Harry Perros, Alumni Distinguished Graduate Professor of computer science at NC State, for publishing a book entitled “Networking Services: Qos, Signaling, Processes.”
Have you ever wondered how apps such as Facetime, Skype, and Google Talk work? How do they find the person you are calling? What transpires form the moment you call someone to the moment you see and hear the other person? Why does the person you speak to over the Internet sound like water babies, or, the movie you are watching suddenly stop at the peak of the drama with the message “rebuffering”?
In this book Perros unravels the mysteries of the signaling protocols that enable us to connect to other people’s smartphones and computers, and the necessary mechanisms in the Internet that allow us to enjoy a movie, or a voice call without interruptions.
Book description: 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. Specifically, the author 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. The material is illustrated with problems and projects. This is a textbook for graduate and senior undergraduate students in computer science and computer engineering, and also a reference book for networking engineers.
