Network Policy Manager (Proof of concept)

Registered by Jesse Brandeburg on 2012-04-27

Users want out-of-the-box high performance networking on their new multi-core Intel servers with multi-queue enabled Network Interface Adapters. Unfortunately, network specific system tuning is so hard that most system administrators can’t achieve the benchmarks scores that we advertise, without navigating a manually intensive and error prone process. Additionally, fully automatic tuning for all workloads is a difficult if not impossible task. The goal of the Network Policy Manager proof of concept is to simplify the tuning by using a simple policy specification (arbitrated by the kernel) that can achieve better network performance than out of the box. We show the state of our current proof of concept, compare some initial results against “out of the box”, and summarize our ideas and direction in order to get further comment.

Affected areas include network drivers, ethtool interface and control, irq affinity, scheduler, multi-queue network core.
