Reviving delay-based TCP for data centers

With the rapid growth of data centers, minimizing the queueing delay at network switches has been one of the key challenges. In this work, we analyze the shortcomings of the current TCP algorithm when used in data center networks, and we propose to use latencybased congestion detection and rate-based transfer to achieve ultralow queueing delay in data centers.
