Networking Services: QoS, Signaling, Processes (Paperback)

Harry Perros

商品描述

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.

商品描述(中文翻譯)

這本書的結構是圍繞著下一代網路(NGN)框架展開的,該框架將傳輸網路、服務和信令協議分為服務層和傳輸層。服務層是建立網路會話的控制平面,而傳輸層則是網路服務數據傳輸的數據平面。在這個背景下,作者詳細解釋了在服務層中用於建立網路服務的信令協議,以及在傳輸網路中用於保證服務質量(QoS)的QoS架構。具體而言,作者解釋了SIP、IMS、MPLS、DiffServ、LDP、RSVP-TE、擁塞控制、RACF和VPN等主題;描述了基於IMS的流行網路服務(如VoIP、在線狀態、即時通訊、視頻會議、多媒體電話、IPTV和服務和設備連續性)的架構;描述了用於確定網路服務容量的排隊理論和模擬技術。該材料通過問題和項目進行了說明。這是一本針對計算機科學和計算機工程的研究生和高年級本科生的教科書,也是網路工程師的參考書。
