Abstract
Multimedia
systems are becoming increasingly networked,
from streaming audio/video from internet
sites to multiple networked sources
and sinks within the home. Many distributed
systems are adopting a "service
based" approach. Middleware architectures
from CORBA through to more recent architectures
such as Web Services, UPnP and Jini
use this terminology. This tutorial
looks at this important topic in distributed
systems from a practical viewpoint,
considering both concepts and the realisation
of these concepts in current technologies.
The topics will be :
- concepts
of service-based systems: advertisement,
discovery, use, garbage collection
- representation
languages for services
- directory
and non-directory systems
- multicast
and unicast advertisement and discovery
- service
invocation
- other
topics such as security and session
management
- Service-based
multimedia systems
- all
topics will be illustrated by Java
examples for web services, Jini,
and UPnP
