Management of Internet Traffic via Aggregation

The IP networking industry is defining ways to differentiate service levels and provide contracted quality of service. Much of the work, such as multi-protocol label switching, is moving toward traffic engineering models for aggregate streams that closely parallel those of ATM networks. A general architecture, similar to that used for ATM connections, is suggested for the traffic management of IP aggregates. This is in contrast with the present approach where the core network basically relies on end-system TCP to provide congestion control and sharing between individual flows rather than their aggregates. The results presented are based on joint work with Alan Chapman of Nortel and Harvard Ph.D. student S. Y. Wang.
SPEAKER BIO
H.T. Kung is William H. Gates Professor of Computer Science and
Electrical Engineering at Harvard. He received his Ph.D. from
Carnegie Mellon and served on their faculty before joining Harvard in
1992. Over the last 25 years, he
has pursued a variety of interests at Carnegie Mellon and Harvard:
algorithms and complexity, database systems, VLSI architectures,
parallel computing, mobile computing, and computer networks.
More recently he has been interested in network architectures
capable of providing quality of service.
