With the growth of data volumes and variety of Internet applications, data centers (DCs) have
become an efficient and promising infrastructure for supporting data storage, and providing …

Data centers (DCs), owing to the exponential growth of Internet services, have emerged as
an irreplaceable and crucial infrastructure to power this ever-growing trend. A DC typically …

TCP's congestion control architecture suffers from notoriously bad performance.
Consequently, recent years have witnessed a surge of interest in both academia and …

Over the past one and half years, we have been using RDMA over commodity Ethernet
(RoCEv2) to support some of Microsoft's highly-reliable, latency-sensitive services. This …

TCP and its variants have suffered from surprisingly poor performance for decades. We
argue the TCP family has little hope of achieving consistent high performance due to a …

An ideal datacenter network should provide several properties, including low median and
tail latency, high utilization (throughput), fair allocation of network resources between users …

The trend towards simple datacenter network fabric strips most network functionality,
including load balancing, out of the network core and pushes it to the edge. This slows …

Today's data centers face extreme challenges in providing low latency. However, fair
sharing, a principle commonly adopted in current congestion control protocols, is far from …

Small RTTs (~ tens of microseconds), bursty flow arrivals, and a large number of concurrent
flows (thousands) in datacenters bring fundamental challenges to congestion control as they …

A detailed examination of evolving traffic characteristics, operator requirements, and network
technology trends suggests a move away from nonblocking interconnects in data center …
