Large-scale data centers play a vital role in supporting the ever growing demand for
computation and storage. These data centers often employ commodity hardware switches …

Traditionally, the networking industry has been dominated by closed and proprietary
hardware and software. Vendors have been controlling the network by hard-coding how …

Cloud interactive data-driven applications generate swarms of small TCP flows that compete
for the small switch buffer space in data-center. Such applications require a small flow …

Due to the partition/aggregate nature of many distributed cloud-based applications, incast
traffic carried by TCP abounds in data center networks. TCP, being agnostic to such …

In data center networks (DCNs), the presence of long-lived TCP flows tends to bloat the
switch buffers. As a consequence, short-lived TCP-incast traffic suffers repeated losses that …

There exists an extensive body of work, spanning more than two decades, on congestion
control schemes and signaling mechanisms. The majority of prior work does not, however …

To meet the deadlines of interactive applications, congestion-agnostic transport protocols
like UDP are increasingly used side-by-side with congestion-responsive TCP. As bandwidth …

Modern data centers host a plethora of interactive data-intensive applications. These are
known to often generate large numbers of short-lived parallel flows that must complete their …

This paper discusses the implementation of RWNDQ, a switch-assisted algorithm to improve
TCP's congestion control in data center networks (DCNs). In particular we demonstrate how …

In today's modern cloud supported applications, the traffic relies on both congestion-
responsive transport protocols like TCP and congestion-oblivious transport like UDP …
