Abstract
In order to realise service deployment on high-performance active nodes,
the problem of installing and confguring software components in
complex, heterogeneous node environments must be addressed. The paper
presents our approach to this problem, called Chameleon. The service
specifcation is kept independent of any particular node architecture.
During the service deployment phase, the service specifcation is re-
solved recursively on each node offering the service and is driven by
node-specifc parameters. The result of this resolution is a tree of
service components, which can differ among different types of nodes. Our
solution allows a service to take full advantage of specific node features,
such as those related to performance or security. The design is illustrated
using a video scaling service.
The talk is based on an invited paper we wrote for SmartNet 2002, see

About the speaker
Bernhard Plattner is a Professor of Computer Engineering at ETH Zurich,
where he leads the communication systems research group. 1996-98, Dr.
Plattner served as the Head of Faculty of Electrical Engineering at ETH
Zurich. He has been the principal investigator or Co-pi of numerous national
and international projects. His research currently focuses on applications
of communication systems and higher layer protocols, and on integrated
services networks. Specifically, he is involved in the development of
multimedia applications for high-speed networks and is exploring new network
architectures, such as active networks. In his earlier work, he directed
research in message handling systems and distributed directories, and
participated in setting up and operation of early experimental X.400
systems. Prof. Plattner is currently the head of the Computer Engineering
and Networks Laboratory at ETH Zurich.
