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 …

Many existing data center network (DCN) flow scheduling schemes minimize flow
completion times (FCT) based on prior knowledge of flows and custom switch functions …

For the widely deployed ECN-based congestion control schemes, the marking threshold is
the key to deliver high bandwidth and low latency. However, due to traffic dynamics in the …

As datacenter network bandwidth keeps growing, proactive transport becomes attractive,
where bandwidth is proactively allocated as" credits" to senders who then can send" …

Recent proposals have leveraged Explicit Congestion Notification (ECN) to achieve high
throughput low latency data center network (DCN) transport. However, most of them …

Multi-tenant datacenters are successful because tenants can seamlessly port their
applications and services to the cloud. Virtual Machine (VM) technology plays an integral …

Over the last several years, datacenter computing has become a pervasive part of the
computing landscape. In spite of the success of the datacenter computing paradigm, there …

The link speed in production datacenters is growing fast, from 1 Gbps to 40 Gbps or even
100 Gbps. However, the buffer size of commodity switches increases slowly, eg, from 4 MB …

New congestion control algorithms are rapidly improving datacenters by reducing latency,
overcoming incast, increasing throughput and improving fairness. Ideally, the operating …
