VTHD++ at Planète, Inria Sophia Antipolis The VTHD++ project is the successor of VTHD(Vraiment Très Haut Débit) project. The goal of VTHD++ is the application deployment and experimentation over very high speed networks (2,5Gbits/s). This page presents PLANETE team contributions within INRIA VTHD++ participation.

Our objectives in VTHD++:

We are involved in S.P.1 (Sub-Project 1) of VTHD++ concerning deployment and exploitation of a very high speed IPv4 experimentation platform with differentiated services and multicast support. More specifically, we are involved in Tasks 3 and 4 of this sub-project:

Task 3, called "WAGON benchmark tool", aims to extend this tool with IP telephony and multimedia trafic generation. The idea is to show that a high speed network such as VTHD++ is an efficient way to transport a large number of of IP telephony communications.
Task 4, called Multicast and Interactive Multi-Users Applications, aims to deploy, experiment and analyse performance of multicast on the VTHD++ network and use a Large Scale Virtual Environment (LSVE) application to validate the results. We are developing a LSVE application called V-Eye which enables a large number of heterogeneous participants to exchange different types of data flows (such as text, audio and video) between them. In a first phase, V-Eye will support SCORE communication architecture based on the general ASM multicast model. Then, in a second phase, V-Eye will support a new communication architecture, based on the SSM multicast model. Moreover, as the next generation of the Internet is likely not to include only very high speed links such as VTHD++ but a large number of heterogeneous links (very high speed backbones, LAN, Wireless LAN, Personal Area Networks, etc.), we are very interested in the support of IP differentiation services on top of such heterogeneous environments. We are developing such an heterogenous network platform in our lab and are currently working on the support of differentiated services for 802.11 WLAN. We will experiment multimedia applications on top of that such as V-Eye.
