Accomplishments in the Quarter
Prepared and presented a demonstration on the use of CANEs for an
intelligent firewall application. The application allows dynamic
addition and deletion of rules for packets to pass/drop at the
firewall, based on packet header matching. This application exercises
most of the basic pieces of the CANEs and Bowman platform. The
demonstration was given at the CANEs/ActiveCast site visit in
Lexington, KY. The application will be included in a suite of
examples on the use of CANEs, to be included in the CANEs final
release.
Analyzed the decomposition of the AER/NCA protocols to extract
a better understanding of how the current CANEs model and implementation
provides support for complex applications. This analysis will
lead to proposed additions and changes to CANEs to provide
better support. (See Plans for the Next Quarter in this area.)
Agreed to host the Fall 2000 DARPA Active Networking
program demonstrations at Georgia Tech. Began initial planning for
facilities and technical support for the demonstrations.
Publications and Presentations
- Zegura presented the paper "Exposing the network: support
for topology-sensitive applications" at OpenArch 2000 in
Tel Aviv, Israel, in March 2000.
- Zegura presented the paper "Bowman: A NodeOS for active
networking" at Infocom 2000 in Tel Aviv, Israel, in March 2000.
- Zegura participated in an OpenArch panel on the topic of
startup opportunities in active networking.
Travel
- Zegura and Merugu traveled to Lexington, KY, to participate in
a CANEs/ActiveCast site visit with DARPA and contracting agency
representatives.
- Zegura attended OpenArch 2000 and Infocom 2000 in
Tel Aviv, Israel. Permission to use contract funds for
international travel was obtained (just) prior to the trip.
Administrative Issues
None to report.
Plans for Next Quarter
- Complete the CANEs project deliverables.
- Gather input from DARPA AN research community on the details
of the facilities for the Fall demonstrations. (To be done
at the May PI meeting in Portland, Oregon.)
- Complete a journal paper submission on the lessons learned in
the experience of implementing the UMass/TASC protocols for
reliable multicast with congestion control on the CANEs/Bowman
platform. We expect that these lessons will be
of interest in the design of platforms for active networking
in general, and especially those platforms that attempt to provide
reasonable performance and support for complex services.
- Participate in a visit by faculty and students from UIUC
to discuss the potential relationship between the Seraphim security
project and the CANEs/Bowman platform, with a specific eye towards
the Fall demos.
- Attend and participate in the DARPA PI meeting in Portland, Oregon,
in May 2000.
