Paper Abstract

More and more network operators plan to use broadband satellite systems as part of their global broadband multimedia infrastructure because of their large geographic coverage, inherent broadcast capabilities, and fast deployment features. The recent advances on Ka-Band transmission, fast on-board switching and spot beam technologies mean that satellites can be employed efficiently to help provide high-speed, global connectivity to users all around the world. Satellite systems are multiple access systems with limited transmission capacity, very limited on-board buffering facilities, and long propagation delays compared to terrestrial network. Because of the limited on-board buffer space, high packet loss could be expected on board the satellite if no special protections were built-in. End-to-end resource management in on-board processing (OBP) satellite networks is key to provide fair and efficient sharing of traffic resources while delivering acceptable Quality of Service (QoS) to users. In this paper, we propose a Weighted Fair Bandwidth-on-Demand (WFBoD) process, which is a Demand Assignment Multiple Access (DAMA) based resource management protocol. It allows the network operator to implement various levels of service segregation by providing both absolute and differential QoS to the end-users by sharing the transmission resources fairly and efficiently. We formulate the problems associated with the implementation of WFBoD in OBP geostationary satellite networks, and present some simulation results in a Bent-Pipe satellite network scenario.
