A new congestion control framework for large bandwidth-delay product networks
Hyogon Kim, David J. Farber · 1995
The performance of adaptive congestion control methods will not scale well with bandwidth increase, due to elongating feedback loop and “wired-in” conservativeness of its rate change algorithms. We prove the point by showing that an experimental approach, with a non-adaptive non-conservative control algorithm, can yield order-of-magnitude larger network power and better bandwidth scalability than TCP Reno for multi-megabit/gigabit networks. This result suggests that generally congestion control algorithms should get more aggressive in high-speed networks, and the additional aggressiveness should be a variable determined by the ratio between transported data size and bandwidth-delay product.
