Description:
The unique characteristics of Satellite Systems, such as wider coverage, broadcasting, and multicasting enable satellites to support broadband applications and services in rural and remote areas. Hybrid satellites/terrestrial networks are suitable for providing multimedia and integrated services for both fixed and mobile users. Moreover, mobile satellite systems are expected to fill the coverage gaps of terrestrial 3G and B3G mobile systems. Recent demands for streaming video, Internet access, and multi-party services require new hybrid network architectures. In particular, satellites are being considered as viable candidates for new broadband data services for fast trains, commercial aircrafts and private business jets. New satellite systems are being developed to support digital video broadcasting using DVB-S and DVB-RCS protocols. Novel information services will be made possible due to accurate positioning systems, e.g., GPS and Galileo.

To make the upcoming satellite network systems fully realizable, meeting the new services and applications, many technical challenges have to be addressed. For example, adaptive resource management, advanced encoding techniques, and routing algorithms required to be developed. To support end-to-end Quality of Service (QoS), layer interaction designs must be investigated. Finally, transport protocols need to address large propagation delays, link impairments, and bandwidth asymmetry.

In this Workshop, Satellite experts from Government, Industry, Academic, and Research Institutions, both from North America and Europe, discuss topics, such as: the Satellite communications Network of Excellence (SatNEx) evolution, fundamental performance issues, protocol effects of various IP over satellite architectural components, on-board router designs and implications, and possible solutions for systems realization. In addition to this, discussion of the requirements for various communication environments, tradeoff analysis between circuit and packet switching, and different protocols, such as protocol enhancing proxy for NASA, DOD, and systems for commercial space applications will be included. End-to-end QoS for next-generation network architecture and DVB-S/RCS protocols will be covered. Inmarsat's Broadband Global Area Network (BGAN) system architecture, services, will be discussed. Cross-layer protocols for multi-service satellite IP networks and parametric optimization will be addressed. This workshop will also cover an overview of satellite-based broadcast to mobile users, S-band systems, e.g., XM-Radio and Sirius and upcoming S-DMB along with the emerging classes of services like user personalized radio programs.
