Investigation of Ethernet switches behavior in presence of contending flows at very high-speed
Résumé
This paper examines the interactions between layer 2 (Ethernet) switches and TCP in high bandwidth delay product networks. First, the behavior of a range of Ethernet switches when two long lived connections compete for the same output port is investigated. Then, the report explores the impact of these behaviors on TCP protocol in long and fast networks (LFNs). Several conditions in which scheduling mechanisms introduce heavy unfair bandwidth sharing and loss burst which impact TCP performance are shown.
