One of the key building blocks of data centers is the network component. Data center networks have received considerable attention in research in recent years with efforts focusing on transforming the existing Ethernet technology to support data center networks. One key missing feature in Ethernet for data center networks is the support of lossless transmission. To address this shortcoming, a comprehensive data traffic management is needed for Ethernet to operate in a data center, and this need has prompted the creation of a number of standards including IEEE 802.1Qbb for priority flow control, IEEE 802.1Qaz for enhanced transmission selection, and also IEEE 802.1Qau for Ethernet congestion management. This talk presents our recent works on data traffic management in data center networks. We first introduce two layer-2 solutions to combat traffic congestion in data center networks. The first solution uses multipathing technique to balance traffic and prevent congestion at local links. When the offered load exceeds the network capacity, our second solution offers controlling of traffic flows based on their priority to avoid network-wide congestion. In layer-3, we introduce multiple congestion points TCP specifically design for data center environment. We show the significant performance benefit when multiple congestion points can be detected in a data path. The talk concludes with sharing of some ongoing works and preliminary results.
