High Performance P4 Software Switch - Week 2

[Yuri Iozzelli]

Hi

Project summary
========================

In this project I would like to implement a modified version of the
reference p4 (http://p4.org) switch on FreeBSD, which uses netmap for
faster packet I/O: the goal would be reaching the 1 Mpps order-of-magnitude
speed (current reference implementation is limited to 150 Kpps for a simple
l2 switch with 2 hosts).


Week 2
=========================

I fixed compilation in freebsd and tested it successfully.

I added support for netmap in packet I/O handling, and it is switchable
with original pcap with a command line argument.

I added some functions to collect performance data and using netmap indeed
speeds up the system.

Overall it is still slow so I am working to find the new bottlenecks.
