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 …

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 …

We report on experiences with Swift congestion control in Google datacenters. Swift targets
an end-to-end delay by using AIMD control, with pacing under extreme congestion. With …

Large language models (LLMs) power a new generation of interactive AI applications
exemplified by ChatGPT. The interactive nature of these applications demands low latency …

Homa is a new transport protocol for datacenter networks. It provides exceptionally low
latency, especially for workloads with a high volume of very short messages, and it also …

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

Traffic optimizations (TO, eg flow scheduling, load balancing) in datacenters are difficult
online decision-making problems. Previously, they are done with heuristics relying on …

Datacenter transports aim to deliver low latency messaging together with high throughput.
We show that simple packet delay, measured as round-trip times at hosts, is an effective …

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

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 …
