Network monitoring is essential for network management and optimization. In modern data
centers, fluctuations in flow rates and network congestion events (eg, microbursts) typically …

Proactive transport has been attractive in modern high-speed and shallow buffered
datacenter networks. At its heart, the link capacity is proactively allocated as credit, and then …

This paper describes the process and operational experiences of deploying the Data Center
TCP (DCTCP) protocol in a large-scale data center network. In contrast to legacy congestion …

The rapid upgrade of link speed and the prosperity of new applications in data center
networks (DCNs) lead to a rigorous demand for ultra-low latency and high throughput. To …

With the development of network-intensive applications like machine learning and cloud
storage, there are two growing trends:(i) RDMA has been widely deployed to enhance …

Conventional host networking features various traffic shaping layers (eg, buffers, schedulers,
and pacers) with complex interactions and wide implications for performance metrics. These …

In this article, we present RoCC, a robust congestion control approach for datacenter
networks based on RDMA. RoCC leverages switch queue size as an input to a PI controller …

The average/tail Flow Completion Times (FCTs) are critical to many datacenter applications.
Congestion control plays a central role in optimizing FCT. Inappropriate congestion control …

The distribution of traffic shows a characteristic of different flow sizes in Data Center
Networks (DCNs), which requires diverse demands for data transmission. However, most …

RDMA over Converged Ethernet (RoCEv2) has been widely deployed to data centers (DCs)
for its better compatibility with Ethernet/IP than Infiniband (IB). As cross-DC applications …
