XCP is a transport protocol that uses the assistance of specialized routers to accurately determine the sender's congestion window size. However, XCP requires the collaboration of all the routers on the data path which is almost impossible to achieve in an incremental deployment scenario of XCP. It has been shown that XCP behaves worse than TCP in the(More)
Wired networks are increasing in size and their power consumption is becoming a matter of concern. Evaluating the end-to-end electrical cost of new network architectures and protocols is difficult due to the lack of monitored realistic infrastructures. We propose an End-to-End energy Cost mOdel and simulator For Evaluating power consumption in large-scale(More)
— High-speed networks are being built using the most up-to-date networking technologies such as optical fibers with dense wavelength multiplexing (DWDM) in order to meet the performance constraints of large scientific problems (grid infrastructures) or new multimedia applications. As technologies are moving forwards, many high-speed network infrastructures(More)
—In networks with very large delay like satellite IP-based networks, standard TCP is unable to correctly grab the available resources. To overcome this problem, Performance Enhancing Proxies (PEPs), which break the end-to-end connection and simulate a receiver close enough to the sender, can be placed before the links with large delay. Although splitting(More)
TFRC is a transport protocol specifically designed to carry multimedia streams. TFRC does not enable a reliable and in order data delivery services. However TFRC implements a congestion control algorithm which is friendly with TCP. This congestion control relies in a feedback mechanism allowing receivers to communicate to the senders an experienced drop(More)
An IP-ERN architecture to enable hybrid E2E/ERN protocol and application to satellite networking. OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract We propose an architecture based on a hybrid E2E-ERN approach allowing ERN protocols to be inter-operable with(More)
TCP(<i>Transmission Control Protocol</i>) uses a loss-based algorithm to estimate whether the network is congested or not. The main difficulty for this algorithm is to distinguish spurious from real network congestion events. Other research studies have proposed to enhance the reliability of this congestion estimation by modifying the internal TCP(More)
XCP is a promising router-assisted protocol due to its high performance and intra-protocol fairness in fully XCP networks. However, XCP is not inter-operable with current E2E protocols resulting in a poor performance of XCP flows when the resources are shared with TCP-like flows. In this paper, we propose a lightweight fairness solution, that can benefit(More)
The assumption of constant bandwidth capacity may be not true anymore because many telco operators and In-ternet providers (ISP) are beginning to deploy Quality of Service (QoS) features with reservation-like or priority-like mechanisms in their networks. Therefore, the available bandwidth for best-effort traffic can vary over time. This paper studies the(More)
