This book provides up to date coverage of the basics of ATM and internet protocols, and characteristics of satellite networks and internetworking between satellite and terrestrial networks

Satellite Networking: Principles and Protocols, Second Edition provides up to date information of the original topics in satellite networking and protocols focusing on Internet Protocols (IP) over satellites, broadband over satellites, next generation IP (IPv6) over satellites, new generation of DVB-S/S2 and DVB-RCS next generations and  new services and applications. It also includes some analytical techniques for evaluation of end to end IP performance and QoS over satellite, reflecting the recent convergence of telecommunication, Internet, broadcasting and mobile networks.

Topics new to this edition: Internetworking with MANET, DVB-S/S2 and DVB-RCS/RCS2 (including TCP/IP over DVB-S/RCS), recent developments in broadband satellite systems, convergence of services and network technologies (including Internet, telecom, mobile, TV, etc.), radio resource management, PEP, I-PEP, SCPS, traffic modelling and engineering with analysis and examples, and  future developments of satellite networking.

•  Provides up to date coverage of the basics of ATM and internet protocols, and characteristics of satellite networks and internetworking between satellite and terrestrial networks (e.g. mobile ad hoc networks), including coverage of new services and applications (e.g. Internet, telecom, mobile and TV)
• Discusses the real-time protocols including RTP, RTCP and SIP for real-time applications such as VoIP and MMC, and explains TCP/IP over satellite and evolution of IPv6 over satellite and beyond

• Be aware of the recent development of broadband satellite systems and standards.

1.1 Applications and Services of Satellite Networks

Satellites are manmade stars in the sky, and are often mistaken for real stars. To many people, they are full of mystery. Scientists and engineers love to give life to them by calling them birds—like birds, they fly but so high that other creatures can only dream of. They watch the earth from the sky at its vantage point, help us to find our way around the world, carry our telephone calls, emails and web pages, and relay TV programmes across the sky. Actually, the altitudes of satellites are far beyond the reach of any real bird. When satellites are used for networking, their high altitude enables them to play a unique role in the global network infrastructure (GNI).

Satellite networking is an expanding field, which has developed significantly since the birth of the first telecommunication satellite, from traditional telephony and TV broadcast services to modern broadband and Internet networks, video on demand and digital satellite broadcasts. Many of the technological advances in networking areas are centred on satellite networking. With increasing bandwidth and mobility demands in the horizon, satellite is a logical option to provide greater bandwidth with global coverage beyond the reach of terrestrial networks, and shows great promise for the future. With the development of networking technologies, satellite networks are becoming more and more integrated into the GNI. Integration of mobile ad hoc networks provides new systems for emergency and rescues services with great mobility. Therefore, internetworking with terrestrial networks and protocols is an important part of satellite networking.

The ultimate goal of satellite networking is to provide services and applications. User terminals provide services and applications directly to users. The network provides transportation services to carry information between users' terminals across the network nodes, switches and routers for a certain distance. Figure 1.1 illustrates a typical satellite network configuration consisting of terrestrial networks, satellites with an inter-satellite link (ISL), fixed earth stations, transportable earth stations, portable and handheld terminals, and user terminals connecting to satellite links directly or through terrestrial networks.

1.1.1 Roles of Satellite Networks

In terrestrial networks, many links and nodes are needed to reach long distances and cover wide areas. They are organised to achieve cost effective deployment, maintenance and operation of the networks. The nat...
