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.
