COLLOQUIUM and connected events
         Computer Science Department, Boston University

Annual WING Lecture

Date:  Monday, December 13, 2004
Time:  11am
Place: MCS 135 (for directions, see www.cs.bu.edu/colloquium)

Each year the Web and Internetworking Group (WING) within BU Computer
Science invites a prominent researcher to campus for a day of discussion
on topics related to computer networking.   This year's WING lecture
will be presented by Prof. Ion Stoica of UC Berkeley.

The day will consist of the following events:

1. Prof. Stoica's talk, entitled "Internet Indirection Infrastructure,"
will be at 11am in MCS 135.  An abstract of Prof. Stoica's talk is
below.   

2. The WING group will have a open house from 2-4 pm in the research lab
(second floor of MCS).   Students will present their research in poster
format and be available for discussion.

All are invited to attend Prof. Stoica's lecture and come to our open
house.

We are looking forward to seeing you on Monday.

Best regards,

Title: Internet Indirection Infrastructure

Abstract:

Attempts to generalize the Internet's point-to-point communication
abstraction to provide services like mobility, multicast, and anycast
have faced challenging technical problems and deployment barriers.  To
ease the deployment of such services, we proposes an overlay-based
Internet Indirection Infrastructure (i3) that offers a rendezvous-based
communication abstraction.  Instead of explicitly sending a packet to a
destination, each packet is associated with an identifier; this
identifier is then used by the receiver to obtain delivery of the
packet. This level of indirection decouples the act of sending from the
act of receiving, and allows i3 to efficiently support a wide variety of
fundamental communication services such as multicast and service
composition.

To increase the usability of i3, we employ a proxy based solution that
provides full support for legacy applications on both Linux and Windows
XP/2000 platforms. To illustrate how the proxy enables users to take
advantage of i3 functionality, I will discuss three examples:
enabling access to machines behind NAT boxes, secure Intranet access,
routing legacy traffic through Bro, an intrusion detection system.

Short biography:

Ion Stoica received his PhD from the Carnegie Mellon University in 2000. He
is an Assistant Professor in the EECS Department at University of
California at Berkeley, where he does research on resource management,
scalable solutions for end-to-end quality of service, and peer-to-peer
network technologies in the Internet. Stoica is the recipient of a
Presidential Early Career Award for Scientists and Engineering (PECASE)
2002, the Sloan Foundation Fellowship (2002), and the ACM doctoral
dissertation award (2001).
