Topic;          "The Reliable Multimedia Streaming Server (RMSS+):
                 the good, the bad and the ugly"

Date:           Monday, 11 March 2002

Time:           4:00pm - 5:00pm

Venue:          Lecture Theater F

ABSTRACT:

Multimedia streaming is one of the most important requirements in
broadband services.  In this talk, we will present the design, analysis
and implementation of the reliable multimedia streaming server (RMSS+).
The RMSS+ is a free software (under GPL) developed by a group of dedicated
and fun-filled students from the Computer Science and Engineering
Department in The Chinese University of Hong Kong. The purpose of the
RMSS+ is to provide unicast or multicast streaming and reliable services
for viewing different multimedia contents. This implies that different
variable bit rate multimedia objects with vastly different bandwidth
requirements can be scheduled under the same server.  Currently, the RMSS+
server is providing the following broadband services in CUHK:  a)
movie-on-demand, b) lecture-on-demand, c) colloquium series, d) musical
juke-box, e) video multicasting services...,etc.  In this talk, we will
present the design philosophy of the RMSS+, including the file system,
disk scheduler, admission control policy, network transmission, buffer
management and object synchronization technique.  We will also discuss
some of the short-comings of the RMSS+ system as well as some exciting
extensions.

Biography:

John Chi-Shing Lui received his Ph.D. in Computer Science from
UCLA.  After his graduation, he naively thought that a career in a
research lab would be great so he joined the IBM Almaden Research
Laboratory/San Jose Laboratory and participated in a parallel I/O
architecture and file system research project. After spending 3 years in
IBM, he decided to try a career in academic and he joined the CS&E
Department in CUHK.  So far, he is having a time of his life, working on
various exciting multimedia and Internet research projects with some
talented students in CUHK.  Prof. Lui has been a visiting professor in
computer science departments at UCLA, Columbia Univ, Univ. of Maryland at
College Park, Purdue Univ. and Univ.  of Massachusetts at Amherst. He is
an affiliated member of the Integrated Media Systems Center (IMSC) at
University of Southern California (USC).  His current research interests
are in data communication networks, distributed multimedia systems, OS
design issues and performance evaluation theory. His personal interests
include films and general reading (currently, finishing the last chapter
of "Lord of the Rings").
