With the proliferation of the Internet, voice over IP and multimedia communication become more and more important. One of the protocol that facilitated this development is Session Initiation Protocol (SIP). SIP is a signaling protocol which manages the session establishment and termination. It can be based on UDP or TCP at the transport layer. In this paper, the strengths and weaknesses of SIP over UDP and TCP are analyzed in satellite environment. The performance issues of SIP related to transport layer over the next generation protocol, IPv6, are studied. The experimentation is carried out on the satellite network testbed at Centre for Communication Systems Research (CCSR), University of Surrey. The results show that SIP performance on UDP is better than on TCP. SIP over TCP, requires more retransmissions due to the congestion control and flow control mechanisms of TCP, resulting in larger call setup time and bandwidth consumption.

“…The model is based on queueing models and the call setup delay had been calculated in single domain and multi-domain scenarios. This paper is continuation of our previous work (Ali et al, 2009a(Ali et al, , 2009b, in which, we have evaluated SIP-based call setup time and other QoS parameters of VoIP over IPv4 and IPv6 satellite environment. The analysis for SIP was based on the unreliable user datagram protocol (UDP) at the transport protocol layer, in which, the reliable delivery of SIP messages is ensured by the application layer.…”

“…The analysis for SIP was based on the unreliable user datagram protocol (UDP) at the transport protocol layer, in which, the reliable delivery of SIP messages is ensured by the application layer. We had recommended that SIP signalling should be improved to reduce the number of SIP messages and call setup time over satellites (Ali et al, 2009b). In this paper, our focus is on the application layer algorithm managing the retransmission of SIP messages to ensure successful call setup.…”

With the proliferation of the internet, voice over IP has penetrated in both terrestrial and satellite networks. One of the popular protocols responsible for its widespread usage is SIP. SIP is the signalling protocol responsible for the session establishment and termination. By default, it uses UDP as the transport layer protocol. As UDP is an unreliable protocol, the retransmission of the SIP messages is managed by the application layer, using exponential backoff algorithm. In this paper, this retransmission algorithm is studied in satellite environment. Based on the shortcomings of this algorithm, a new algorithm is proposed. The performance of the new algorithm is tested and evaluated on the satellite network testbed at Centre for Communication Systems Research (CCSR), University of Surrey. The results show that the performance of the new algorithm is better than the basic one, in terms of number of retransmissions of SIP messages and their bandwidth consumption, in addition to reduction in call setup time.

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. Keywords-Active I. 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...
