ABSTRACT
Reactive congestion control (RCC) protocols have undergone decades of evolution, where senders first send data packets and then back off when congestion occurs. Recently, there has been a surge of interest in proactive congestion control (PCC) that allocates bandwidth before transmission. Despite its potential, we found that there are certain scenarios where PCC may fall short. In this paper, we aim to provide a comprehensive understanding of PCC and motivate further exploration of this area. We conduct case studies and leverage NS3 simulations to compare state-of-the-art PCC with RCCs, delving into the real dilemma of PCC.

Harmonia: Explicit Congestion Notification and Credit-Reservation Transport Converged Congestion Control in Datacenters
AbstractBursty traffic and thousands of concurrent flows incur inevitable network congestion in datacenter networks (DCNs) and then affect the overall performance. Various transport protocols are developed to mitigate the network congestion, including ...
Configurable active multicast congestion control
A multicast congestion control and avoidance scheme is indispensable for group-based applications to fairly share and efficiently use network resources with unicast applications and maintain the stability of the Internet. It is difficult for the ...
