Resource management in a cloud environment is a hard problem, due to: the scale of
modern data centers; the heterogeneity of resource types and their interdependencies; the …

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 …

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 …

Modern datacenter networks provide very high capacity via redundant Clos topologies and
low switch latency, but transport protocols rarely deliver matching performance. We present …

We present the design, implementation, and evaluation of CONGA, a network-based
distributed congestion-aware load balancing mechanism for datacenters. CONGA exploits …

Datacenter networks employ multi-rooted topologies (eg, Leaf-Spine, Fat-Tree) to provide
large bisection bandwidth. These topologies use a large degree of multipathing, and need a …

In this paper we present pFabric, a minimalistic datacenter transport design that provides
near theoretically optimal flow completion times even at the 99th percentile for short flows …

Datacenter networks deal with a variety of workloads, ranging from latency-sensitive small
flows to bandwidth-hungry large flows. Load balancing schemes based on flow hashing, eg …
