Differential congestion notification: taming the elephants

Long Le, J. Aikat, K. Jeffay, F.D. Smith
Proceedings of the 12th IEEE International Conference on Network Protocols, 2004. ICNP 2004.  
Our approach, called differential congestion notification (DCN), distinguishes between "small" flows and "large" high-bandwidth flows and only provides congestion notification to large high-bandwidth flows  ...  However, use of the ECN (explicit congestion notification) signaling protocol was required to outperform drop-tail queuing.  ...  In contrast, providing early congestion notification to elephants can lead to abatement of congestion and more efficient use of the network.  ...

Taming uncertainty in distributed systems with help from the network

Joshua B. Leners, Trinabh Gupta, Marcos K. Aguilera, Michael Walfish
2015 Proceedings of the Tenth European Conference on Computer Systems - EuroSys '15  
When a remote process does not respond, the application cannot tell if the process or network have failed, or if they are just slow.  ...  We show that, under Albatross, distributed applications can bypass the complexity caused by network failures and that they become more available.  ...  The presentation of this paper was greatly improved by the careful comments of Dejan Kostić, Jinyang Li, Scott Shenker, Riad Wahby, and the anonymous reviewers of EuroSys, OSDI, and SIGCOMM.  ...
