“…The number of nested resources does not appear to suit one congestion algorithm over another. These results with regard to TCP variants confirm the work done by other researchers [39]. We conclude from these results that using a TCP Hybla connection at the ground node will give slightly better performance in terms of web page load time for the end-users.…”

Abstract-The proliferation of sophisticated web technologies requires efficient tools to evaluate the performance of HTTP traffic under various conditions. In this paper, we present HTTP-Automated Evaluation (HTTP-AE) as a multi-user client-side framework for evaluating HTTP performance. The framework can be used to evaluate mechanisms, which improve HTTP performance. We present several case studies in which HTTP-AE is used to evaluate three HTTP acceleration mechanisms deployed in an emulated satellite system. These case studies show that the framework can be used to test different design aspects that may affect HTTP performance. Hence, by using the proposed framework, one can determine the advantages and limitations of different network design configurations.

“…Figures 14-18 show that Hybla, which is designed for high latency links, has the best performance while Vegas results in the worst performance of the four evaluated TCP variants. TCP Vegas is greatly impeded by the long RTT [39]. The number of nested resources does not appear to suit one congestion algorithm over another.…”

“…To some extent, our work can be seen as a continuation of the work developed by Caini et al [5], in which several TCP variants were analyzed over a DVB-S GEO satellite test bed. To the best of our knowledge, our study is the first one that analyzes the TCP performance considering a DVB-S2/ETSI-BSM QoS scenario.…”

This paper presents an analysis of several Transmission Control Protocol (TCP) variants working over a digital video broadcasting-second generation (DVB-S2) satellite link with the support of the Differentiated Services (DiffServ) architecture to provide quality of service (QoS). This analysis is carried out using the NS-2 simulator tool. Three TCP variants are considered: SACK TCP, Hybla TCP, and CUBIC TCP. These TCP variants are taken as a starting point because they have proven to be the most suitable variants to deal with long delays present in satellite links. The DVB-S2 link also introduces the challenge of dealing with variable bandwidth, whereas the DiffServ architecture introduces the challenge of dealing with different priorities. In this paper, we propose a DiffServ model that includes a modified queuing mechanism to enhance the goodput of the assured forwarding traffic class. This modified DiffServ model is simulated and tested, considering the interaction of the selected TCP variants. In addition, we present evaluation metrics, significant simulations results, and conclusions about the performance of these TCP variants evaluated over the proposed scenario. As a general conclusion, we show that CUBIC TCP is the TCP variant that shows the best performance in terms of goodput, latency, and friendliness.

“…There is no bottleneck link in single link and single data flow simulation, the network throughput is dependent on the random error rate of link [12]. The results showed that the instantaneous average throughput of TCPW-I is approximately twice that of TCPW.…”
