Tomorrow (thursday) at 12noon, Ilias Marinos from Cambridge will be
giving a practice talk for his Hotnets presentation.  This is very cool
work he started at UCL for his MSc and continued at Cambridge.  Sorry
for the short notice.  Room is probably Roberts 422, but I'll let you
know if that changes.

Title:
Network Stack Specialization for Performance

Abstract:
Contemporary network stacks are masterpieces of generality, supporting a
range of edge-node and middle-node functions. This generality comes at
significant performance cost: current APIs, memory models, and
implementations drastically limit the effectiveness of increasingly
powerful hardware. 

We present Sandstorm, a clean-slate, specialised userspace network stack
that exploits knowledge of web server semantics and improves throughput
over current off-the-shelf designs.  Our approach is compared to the
conventional FreeBSD and Linux network stacks, demonstrating more than
~3.5x throughput improvement, while experiencing low CPU utilisation and
linear scaling on multicore systems.
