TITLE: ΠP — Named Information Management

ABSTRACT:
Named information is all the rage: Content-Centric Networks, Named-Data Networks, Content-Delivery Networks, Information Centric Networks, all address data consumption with the help of storage nodes around the network that help prevent having to copy data over the same network links time and again.

Very few, if any of these systems pay attention to all the other information: information that is updated, private information that needs to be protected, replicated information that has consistency requirements, real-time information in interactive exchanges, and information being handled by mobile nodes while changing their connectivity.

We are constructing Πp, a set of protocols supporting a federated, internet-scale infrastructure that integrates storage and communication with particular support for information privacy ad integrity, mobility and consistency management. We've modelled the interactions on file I/O, so that existing applications, with a minimal Πp front end, can use Πp without any change.

I'll talk about the protocols, how they support mobility, lowest-possible latency, privacy and integrity, consistency, and, of course, content distribution.

BIO:
Sape Mullender is director of Network Systems in Alcatel-Lucent's Bell Laboratories and an extraordinary professor of computer science at the University of Twente in the Netherlands.

He has worked extensively in operating systems, multimedia systems, wireless systems research and is now working on the integration of processing, communications and storage. He was a principal designer of the Amoeba distributed system, and contributed to the Nemesis multimedia operating system, Plan 9 and Inferno.

He received his Ph.D. from the Vrije Universiteit in Amsterdam, worked at the Centre of Mathematics and Computer Science (CWI) in Amsterdam. From 1991 to 1998 he was a full professor in Twente; he now holds the chair there part time. In the 90s, he also was the Northernmost computer science professor in the world at the University of Tromsø in Norway. He started work at Bell Labs in 1997.

He has published papers on file systems, high-performance RPC protocols, locating migratable objects in computer networks, and protection mechanisms, and has been involved in the organization of a series of advanced courses on distributed systems — Arctic'88, Fingerlakes'89, Bologna'90, Karuizawa'91, Lisboa'92, and Redmond'93.
