[ns] a new research using ns

[Arnaud Legout <Arnaud.Legout@eurecom.fr>]

hello,
I am pleased to announce you a new research paper recently accepted for
publication at
ACM Sigmetrics'00 using ns.

We use ns for the evaluation of a new cumulative layered multicast
congestion control protocol (called PLM). Thanks to the VINT team for
developing and maintaining such a good tool for research.

I hope to make the ns scripts available soon.

The paper reference is:
A. Legout, and E. W. Biersack. 
PLM: Fast Convergence for Cumulative Layered Multicast Transmission
Schemes. 
In Proceedings of ACM SIGMETRICS'2000, Santa Clara, California, USA,

Arnaud.

abstract of the paper:
A major challenge in the Internet is to deliver live audio/video content
with a
good quality and to transfer files to large number of heterogeneous
receivers. Multicast
 and  
cumulative layered transmission are two mechanisms of interest to
accomplish this
task efficiently. However, protocols using these mechanisms suffer from
slow
convergence time, lack of inter-protocol fairness or TCP-fairness, and 
loss induced by the join experiments.

In this paper we define and investigate the properties of a new
multicast
congestion control protocol (called PLM) for 
audio/video and file transfer applications  based on a cumulative
layered multicast
transmission. A fundamental contribution of this paper is the
introduction and
evaluation of a {\it new} and {\it efficient} technique based on packet
pair
to infer which layers to join. We evaluated PLM for a large variety of
scenarios
and show that it converges fast to the optimal link utilization, induces
no loss
to track the available bandwidth, has inter-protocol fairness and
TCP-fairness, and
scales with the number of receivers and the number of sessions.
Moreover, all
these properties hold in self similar and multifractal environment.
