Accomplishments in the Quarter
The majority of our effort during this period was devoted
to development of an integrated demonstration for the December
DARPA meeting, as well as hosting the meeting.
In these areas, we accomplished the following:
- Implemented a generic display capability to allow us
to display Bowman and CANEs performance metrics in real-time,
during the demonstration and for debugging purposes.
- Ported the Washington University code server for use
as a CANEs code server. This required changing the code
to create an interface appropriate for CANEs.
- Implemented the per-flow, link-level authorization
of bandwidth. The scheme was operational at the time of
the December demonstrations, but a suspected problem related
to interaction with the WAN-emulators prevented demonstration.
- Transformed the U. of Illinois security guardian to
a stand-alone process with a UDP socket interface, to support
calls from our C-based Bowman/CANEs platform.
- Led the Team 4 demonstration during the December demonstration
meeting in Atlanta. Our team was able to demonstrate
delivery of real-time video using the
UMass/TASC active error recovery protocols, implemented on
the CANEs/Bowman platform, with a Seraphim security layer
between the CANEs EE and the Bowman NodeOS. The Maude
system from Stanford/SRI was used to check correctness
of the AER protocols.
- Hosted the December demonstration meeting. This included
providing technical support during the meeting, arranging for shipments,
and supporting other group needs during the meeting.
Publications and Presentations
- A paper entitled "Active Reliable Multicast on CANEs:
A Case Study" was accepted for publication in OpenArch'01.
- Calvert and Zegura gave presentations as part of
the Team 4 demonstration during the December DARPA meeting.
- Zegura traveled to New York City in October 2000 for
the Infocom 2001 program committee meeting.
- Calvert traveled to Georgia Tech in November 2000
for a Team 4 demonstration planning meeting.
- Calvert and U. of Kentucky student(s) traveled to Atlanta in December 2000
for the DARPA meeting. A group of Georgia Tech students also
attended the meeting, requiring registration, but not travel.
None to report.
Plans for Next Quarter
- Work on finalizing deliverables for the CANEs project,
which will terminate in June 2001.
- Handle post-meeting wrap-up details, including financial
details related to use of GCATT space.
- Continue development of a packet classifier suitable
for large and varying rule tables that must operate at high speed.
Such a classifier has applications within active networking,
as well as more generally.
