Datacenters provide cost-effective and flexible access to scalable compute and storage
resources necessary for today's cloud computing needs. A typical datacenter is made up of …

Upstart space companies are actively developing massive constellations of low-flying
satellites to provide global Internet service. We examine the problem of designing the inter …

The interconnect is one of the most critical components in large scale computing systems,
and its impact on the performance of applications is going to increase with the system size …

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 …

Despite extensive efforts to meet ever-growing demands, today's datacenters often exhibit
far-from-optimal performance in terms of network utilization, resiliency to failures, cost …

Recent studies have observed that large data center networks often have a few hotspots
while most of the network is underutilized. Consequently, numerous data center network …

While prior work has explored many proposed datacenter designs, only two designs, Clos-
based and expander-based, are generally considered practical because they can scale …

The maintenance of efficient and robust overlay networks is one of the most fundamental
and reoccurring themes in networking. This article presents a survey of state-of-the-art …

Emerging optical technologies introduce opportunities to recon gure network topologies at
runtime. The resulting topological exibilities can be exploited to design novel demand-aware …

We present Elmo, a system that addresses the multicast scalability problem in multi-tenant
datacenters. Modern cloud applications frequently exhibit one-to-many communication …
