Ultimately,
our goal is to develop reliable and secure
|
|
|
multicast
solutions (pending finding unsuspecting students
|
|
|
to do
the work).

BCAST
used as starting point with a NACK-based
|
|
|
retransmission
scheme to further increase PDR

Lessons
learned to date: congestion control is more
|
|
|
important
than packet retransmission scheme (when
|
|
|
network
is congested, NACKs make bad situation worse,
|
|
|
independent
of network capacity)

Implemented
BCAST on Linux laptops, with some
|
|
|
preliminary
work comparing simulation results and testbed
|
|
measurements
(using MNE, driven by NS2 traces)
|
|
|
|

Unfortunately,
testbed measurements correspond neither
|
|
|
quantitatively
nor qualitatively with NS2 results
