The HSBQ Algorithm with Triple-play Services for Broadband Hybrid Satellite Constellation Communication System

Abstract

Abstract-The HSBQ algorithm is the one of active queue management algorithms, which orders to avoid high packet loss rates and control stable stream queue. That is the problem of calculation of the drop probability for both queue length stability and bandwidth fairness. This paper proposes the HSBQ, which drop the packets before the queues overflow at the gateways, so that the end nodes can respond to the congestion before queue overflow. This algorithm uses the change of the average queue length to adjust the amount by which the mark (or drop) probability is changed. Moreover it adjusts the queue weight, which is used to estimate the average queue length, based on the rate. The results show that HSBQ algorithm could maintain control stable stream queue better than group of congestion metric without flow information algorithm as the rate of hybrid satellite network changing dramatically, as well as the presented empiric evidences demonstrate that the use of HSBQ algorithm offers a better quality of service than the traditionally queue control mechanisms used in hybrid satellite network.

INTRODUCTIONIn the next-generation Global Area Network (GAN), satellite networks are expected to complement the coverage of the globalized networks in instances where they best serve the communication needs of users. In recent years, Micro Systems Canada Inc. (MSCI) [1] has been deployed to provide firm global coverage communications to the public. To increase the feasibility of success of commercial high-speed broadband data satellite networks, it is important for designers to consider both wired and wireless techniques integration together. The Internet wide application which is working with the rapid development of the satellite technique, the hybrid satellite network has been becoming a research focus. For the challenges, efficient utilization of the capital investment in the face of high uncertainty in traffic demand needs to be considered during the hybrid satellite network design stage. A queue sizes oscillations large range make the queue suffer, which will make early congestion notification hard and finally lead to congestion [4].Recent research activities have placed much emphasis on various the queue weight techniques for the active queue management over satellite segment assuming bottleneck link are known. A variety of Hybrid Satellite -Blue Queue (HSBQ) algorithm aims to evaluate for triple-play service applications over Broadband Hybrid Satellite Constellation Communication System (BHSCCS) [5] using the network system based on COMMStellation TM satellite system has been proposed in this research. This paper proposes a ratebased stabilization for HSBQ. This algorithm adjusts the queue weight, which is used to estimate the average queue length, based on the rate; moreover, it uses the changes of the average queue length to adjust the amount by the mark or drop of probability which is changed. This paper is organized as follow: Section II describes the related works which is queue system, Section II...
