High Performance, Versatile, and Cost Effective Broadband Satellite Networking System for GIG

San Diego Research Center proposes to develop an end-to-end satellite networking architecture with corresponding hardware, software, and networking protocol stack specifications to provide high satellite link utilization, low access latency (from terminal to hub), high end-to-end performance and security, and the capability to send emergency and high priority traffic at any given time. This design will leverage the Digital Video Broadcast - Return Channel via Satellite (DVB-RCS) standard to the extent possible in order to achieve low system cost provided by the wide adoption of the standard by the satellite industry. Our approach consists of: (i) enhancing the dynamic resource allocation algorithm of DVB-RCS to support end-to-end QoS specified by Multi-Protocol Label Switching standard; (ii) incorporating accurate prediction to greatly reduce the latency penalty caused by large propagation delay and bandwidth-on-demand feature; (iii) simultaneously supporting HAIPE and TCP performance enhancing features that are inherently in conflict by investigating the new promising transport protocol named eXplicit Transport Protocol (XCP); and (iv) leveraging hardware, software and protocols of existing and evolving DVB-RCS technologies. The overall design will allow for seamless integration of the proposed satellite system with the Global Information Grid while enjoying low development cost.
