TCP/ATM Experiences in the MAGIC Testbed
This paper describes performance measurements taken in the MAGIC gigabit
testbed relating to the performance of TCP in wide area ATM networks.
The behavior of TCP with and without cell level pacing is studied.
In particular, we focus on results that indicate that the TCP rate
control mechanism alone is inadequate for congestion avoidance and
control in wide-area gigabit networks.
We also present results showing that TCP augmented by cell-level
pacing addresses these problems and allows the full bandwidth capacity
to be utilized. These results demonstrate the viability of high
performance distributed systems based on wide area ATM networks
given the proper ATM traffic management infrastructure.
