Many network applications, eg, industrial control, demand ultra-low latency (ULL). However,
traditional packet networks can only reduce the end-to-end latencies to the order of tens of …

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 …

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 …

Congestion control (CC) is the key to achieving ultra-low latency, high bandwidth and
network stability in high-speed networks. From years of experience operating large-scale …

Commodity network devices support adding in-band telemetry measurements into data
packets, enabling a wide range of applications, including network troubleshooting …

The increasing gap between the growth of datacenter traffic and electrical switch capacity is
expected to worsen due to the slowdown of Moore's law, motivating the need for a new …

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 applications demand high throughput (40Gbps) and ultra-low latency (<
10 μs per hop) from the network, with low CPU overhead. Standard TCP/IP stacks cannot …

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 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 …
