For those interested in high speed networks,
we have a different and quite simple approach to improve TCP performance in
high speed networks.
The approach is based on AIMD algorithm proposed by Chiu and Jain in
1989. The difference from AIMD is at the portion of congestion window that is
affected by multiplicative decrease. We named this scheme AIMD-FC: Additive
Increase Multiplicative Decrease - Fast Convergence.
The proposed algorithm is compatible with the AIMD of TCP and needs minor
changes. The white paper can be found at
The NS-2 drivers will be available at the same web page as soon as a small
documentation is available.
