CANEs: Composable Active Network Elements
Quarterly Status Report
Period: June 11, 1998 - September 11, 1998
Georgia Tech Faculty:
Ramkumar Krishnan (MS student)
Accomplishments in the Quarter
We extended our investigations into active support mechanisms for multicast
congestion control. Our
results (obtained using our simulator AN-Sim), show that active mechanisms
have significant advantages
over "traditional" receiver-based congestion controlmechanisms from
the standpoint of reaction to the onset and easing of congestion and of
maximizing the utility of delivered data at each receiver.
These results are reported in a paper submitted to Infocom '99.
We hosted the July Active Nets Workshop in Atlanta. Calvert
led discussion of the remaining issues with the architectural framework
document, and the resolution of those issues. The document is now
in "Last Call" stage. Zegura presented a proposal for creating virtual
topologies for the ABONE.
We wrote a tutorial article describing the architectural framework along
with applications for active networks, which will appear in the October
1998 issue of IEEE Communications Magazine.
We continued our investigations of active support for wide-area
server selection, management techniques for soft state at active nodes,
fast packet classification for active routers, and automated virtual topology
creation and management, as well as design and implementation of the CANEs
Publications and Presentations
Calvert (editor) released the final draft version of the Architectural
Framework document. This document is a product of node
architecture working group.
Calvert was named Program Chair of the IEEE Conference on Open Architectures
and Network Programming, to be held in March 1999.
Bhattacharjee presented his PhD dissertation proposal in the College of
Computing at Georgia Tech in August.
Student Joe Dixon attended SIGCOMM '98 in Vancouver.
Student Shashidar Merugu is an intern at NEC Research in Mountain View,
Ken Calvert moved to the Department of Computer Science at the University
of Kentucky in August. A collaboration plan has been submitted to
Hilarie Orman, Program Manager, and a subcontract is under negotiation.
Carmen Emily Zegura was born 23 August, to Ellen and Dan Zegura.
These two events will have some effect on our progress, but we have
taken steps that we believe are adequate to ensure that it is temporary
and minimized. The PIs remain in regular contact with each other and with
Plans for Next Quarter
Students Bhattacharjee and Dixon plan to spend at approximately two weeks
each at the University of Kentucky, working with Calvert. These visits
will occur in November or December. They will focus on implementation
of the CANEs platform and on fast packet-demux techniques for the
We will continue our investigation of active congestion control techniques
for multicast video, as well as our investigations into soft-state management
