This paper addresses the problem of choosing the best streaming policy for distortion optimal multipath video delivery, under delay constraints. The streaming policy consists in a joint selection of the video packets to be transmitted, as well as their sen ...
The Internet provides no information on the fate of transmitted packets, and end systems cannot determine who is responsible for dropping or delaying their traffic. As a result, they cannot verify that their ISPs are honoring their service level agreements ...
This paper addresses the problem of efficiently delivering a layered media stream from multiple senders to a single receiver, over channels that present correlated packet loss patterns. Using a digital fountain approach, the performance of a distributed st ...
In this paper we examine performance of the switches with output buffers for traffic with reservations and best-effort traffic. Packets are scheduled according to the Deficit Round Robin (DRR) algorithm. The DRR has been modeled, and quality of service in ...

This paper deals with flow investigations using endoscopes in a single-injector reduced scale Pelton turbine performed with a CMOS high-speed camera. Both onboard and external visualizations techniques of the flow in a bucket are presented. The flow observ ...
We consider queueing networks (QN) with feedback loops roamed by "intelligent" agents, able to select their routing on the basis of their measured waiting times at the QN nodes. This is an idealized model to discuss the dynamics of customers who stay loyal ...
Designing a power-efficient interconnection architec- ture for MultiProcessor Systems-on-Chips (MPSoCs) satisfying the application performance constraints is a nontrivial task. In order to meet the tight time-to-market constraints and to effec- tively hand ...

The design of Pelton turbines has always been more difficult than that of reaction turbines, and their performances lower. Indeed, the Pelton turbines combine 4 types of flows: (i) confined, steady-state flow in the piping systems and injector, (ii) free w ...
A system for sender-driven video streaming from multiple servers to a single receiver is considered in this paper. The receiver monitors incoming packets on each network path and returns, to the senders, estimates of the available bandwidth on all the netw ...
