We present SWAN, a system that boosts the utilization of inter-datacenter networks by
centrally controlling when and how much traffic each service sends and frequently re …

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 networks (DCNs) are constantly evolving due to various updates such as switch
upgrades and VM migrations. Each update must be carefully planned and executed in order …

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 …

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 …

As one of the fundamental infrastructures for cloud computing, data center networks (DCN)
have recently been studied extensively. We currently use pure software-based systems …

Many data center network (DCN) applications require explicit routing path control over the
underlying topologies. This paper introduces XPath, a simple, practical and readily …

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 …

This paper presents Blender, a framework that enables network operators to improve tenant
performance by tailoring the network's behavior to tenant needs. Tenants may upgrade their …

Today's data centers offer tremendous aggregate bandwidth to clusters of tens of thousands
of machines. However, because of limited port densities in even the highest-end switches …
