Abstract
In this thesis, we propose router mechanisms to regulate unresponsive best-effort traffic. By unresponsive traffic, we mean flows that do not reduce their sending rate in response to congestion. The goal of the proposed mechanisms is to drop undeliverable packets (packets that are dropped somewhere in the network before they reach their destination) as close to the periphery of the network as possible. The key ideas of our approach are: (1) edge routers keep track of incoming flows and their arrival rates; (2) non-edge routers use RED (Random Early Detection) for queue management and generate rate-limited source quenches on packet drops to advise sources to reduce their sending rates; and (3) edge routers snoop on source quenches passing through them and use them to control per-flow regulators. Regulators adjust their maximum sending rate using a multiplicative-decrease, additive-increase discipline. A decrease is triggere...
