Programmable data plane technologies enable the systematic reconfiguration of the low-
level processing steps applied to network packets and are key drivers toward realizing the …

Datacenters provide cost-effective and flexible access to scalable compute and storage
resources necessary for today's cloud computing needs. A typical datacenter is made up of …

Datacenter applications demand microsecond-scale tail latencies and high request rates
from operating systems, and most applications handle loads that have high variance over …

This paper presents our design and experience with a microkernel-inspired approach to
host networking called Snap. Snap is a userspace networking system that supports Google's …

In recent years, spurred on by the development and availability of programmable NICs, end
hosts have increasingly become the enforcement point for core network functions such as …

The move from hardware middleboxes to software network functions, as advocated by NFV,
has proven more challenging than expected. Developing new NFs remains a tedious …

By moving network appliance functionality from proprietary hardware to software, Network
Function Virtualization promises to bring the advantages of cloud computing to network …

Software switches are emerging as a vital measurement vantage point in many networked
systems. Sketching algorithms or sketches, provide high-fidelity approximate measurements …

The recently proposed dataplanes for microsecond scale applications, such as IX and
ZygOS, use non-preemptive policies to schedule requests to cores. For the many real-world …

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 …
