Datacenters need networks that support both low-latency and high-bandwidth packet
delivery to meet the stringent requirements of modern applications. We present Opera, a …

Datacenter networks provide high path diversity for traffic between machines. Load
balancing traffic across these paths is important for both, latency-and throughput-sensitive …

Datacenter workloads have evolved from the data intensive, loosely-coupled workloads of
the past decade to more tightly coupled ones, wherein ultra-low latency communication is …

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

Datacenter networks should support high network utilization. Yet today's routing is typically
load agnostic, so large flows can starve other flows if routed through overutilized links. Even …

In this paper, we propose an unorthodox topology for datacenters that eliminates all
hierarchical switches in favor of connecting nodes at random according to a small-world …

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 …

Providers of" Infrastructure-as-a-Service" need datacenter networks that support multi-
tenancy, scale, and ease of operation, at low cost. Most existing network architectures …

The importance of minimizing flow completion times (FCT) in datacenters has led to a
growing literature on new network transport designs. Of particular note is pFabric, a protocol …

Scale-out architectures supporting flexible, incremental scalability are common for
computing and storage. However, the network remains the last bastion of the traditional …
