Satellite Networking: Principles and Protocols
Format: PDF / Kindle (mobi) / ePub
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
on. The use of different descriptors allows the transmission of different kinds of event information, for example for different service types. Time and date table (TDT): The TDT gives information relating to the present time and date. This information is given in a separate table due to the frequent updating of this information. The format and semantics of DVB-RCS tables description follow the DVB-RCS standard specification including the following: RCS map table (RMT): The RMT describes
channel consists of streams; stream consists of connections; and connection consists of IP flows. Figure 6.56 illustrates a typical arrangement of unicast connections from one RCST-A attached to one single sub-net transmitting traffic towards the TDM1: A high priority connection towards RCST3 is identified by (ch_ID-1, PID A-1 HP, MAC address RCST3). A low priority connection towards RCST2 is identified by (ch_ID-1, PID A-1 LP, MAC address RCST2). Figure 6.56 Relationships between the

beams, each illuminating a single small area at a time. Narrow beam-width allows efficient reuse of the spectrum and resulting high system capacity, high channel density and low transmitter power. However, if this small beam pattern swept the earth's surface at the velocity of the satellite, a terminal would have a very short period of time for communication before the next handover procedure. As in the case of terrestrial cellular systems, frequent hand-offs result in inefficient channel
systems. Using essentially the same optical fibre, a synchronous network is able to significantly increase available bandwidth while reducing the amount of equipment in the network. In addition, the provision within the SDH for sophisticated network management introduces significantly more flexibility into the network. Deployment of synchronous transmission systems is straightforward due to their ability to interwork with existing plesiochronous systems. The SDH defines a structure which
