Software‐defined networking (SDN) is one of the most prevailing networking paradigms in
current and next‐generation networks. Basically, the highly featured separation of control …

Data centers are widely used for big data analytics, which often involve data-parallel jobs,
including query and web service. Meanwhile, cluster frameworks are rapidly developed for …

Datacenter transports aim to deliver low latency messaging together with high throughput.
We show that simple packet delay, measured as round-trip times at hosts, is an effective …

This paper introduces Copa, an end-to-end congestion control algorithm that uses three
ideas. First, it shows that a target rate equal to 1=(δd q), where dq is the (measured) …

Given the wide adoption of disaggregated storage in public clouds, networking is the key to
enabling high performance and high reliability in a cloud storage service. In Azure, we …

Small RTTs (~ tens of microseconds), bursty flow arrivals, and a large number of concurrent
flows (thousands) in datacenters bring fundamental challenges to congestion control as they …

Round-trip time (RTT) is a central metric that influences end-user QoE and can expose traffic-
interception attacks. Many popular RTT monitoring techniques either send active probes …

Increasingly stringent throughput and latency requirements in datacenter networks demand
fast and accurate congestion control. We observe that the reaction time and accuracy of …

As datacenter network bandwidth keeps growing, proactive transport becomes attractive,
where bandwidth is proactively allocated as" credits" to senders who then can send" …

Managing Network Function (NF) service chains requires careful system resource
management. We propose NFVnice, a user space NF scheduling and service chain …
