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 5 ========================= I improved the lock-free queue to support batching and modified the existing code to take advantage of it. I am also starting to implement a priority queue based on it. The simple target I am working on is complete and it reaches a throughput of 2 Mpps for the simplest p4 program, and a throughput of 650 Kpps for a more realistic one. Now I will focus to bring in more features, like packet replication and learning.
