This study provides some new insights into the scalability of reliable group communication mechanisms using overlays. These mechanisms use individual TCP connections...

A recent means for enabling multicast in the Internet involves deploying network overlays where end-systems participate in the forwarding of data to other end-systems....

We present and validate TICP, a TCP-friendly reliable transport protocol to collect information from a large number of receivers spread over the Internet. TICP is a...

In this paper we show how to build a fully secure and efficient group communication service between several sites. This service is built on top of a VPN environment...

This paper introduces a novel approach, SVSoA, for the streaming of hierarchic- ally encoded videos using multicast IP, which fully benefits from the Asynchronous...

In this document, we propose a new multicast session directory system, «Channel Reflector». One of the goals of this system is to provide a feasible channel...

This paper addresses the problem of congestion control for video transmission in large multicast groups. In order to solve the well-known feedback implosion problem in...

New technologies and the deployment of mobile and nomadic services are driving the emergence of complex communications networks, that have a highly dynamic behavior....

Currently, group membership management in IP Multicast and Anycast can be abused in order to launch denial-of-service (DoS) attacks. The root of the problem is that...

An adhoc wireless network is a network composed of mobile hosts with no fixed infrastructure and no central administration. The main constraints in these networks are...

We propose two novel on-line estimation algorithms to determine the size of a dynamic multicast group. We first use a Wiener filter to derive an optimal estimator for...

We consider a flow of data packets from one source to many destinations in a communication network represented by a random oriented tree. The multicast mode is...

In this paper we propose an optimal on-line estimation algorithm for determini- ng the size of a dynamic multicast group. By using diffusion approximation and Kalman...

Considerable efforts have focused on congestion control protocols for large-scale multicast applications, but in most cases, these consider only single rate sessions....

Motivated by wavelength division multiplexing in all-optical networks, we consider the problem of finding a set of paths from a fixed source to a multiset of...
