Network Latency Control in Data Centres (Dagstuhl Seminar 16281)

This report documents the program and the outcomes of Dagstuhl Seminar 16281 "Network Latency Control in Data Centres". This seminar explored existing and future techniques for controlling data centre latency and thus explores research directions in the new field of data centre latency control in networking research. This need for a new research direction is motivated by the fact that traditional networking equipment and TCP-IP stacks were designed for wide-area networks, where the goal is to maximize throughput, and the control loop between end systems is measured in 10s of milliseconds. Consequently, this seminar discussed new research direction for data center latency control across the entire software and hardware stack, including in-network solutions, end-host solutions, and others
