Of course, this is only 1Gb Ethernet, so 1.488 million 64-byte packets per second is easily achieved, and the system doesn't break a sweat. Only a single core is in use on all three boxes. CPU load (single core!) on the DUT is about 10-13%. IIRC, kernel forwarding using the same setup is ~250Kpps and the system is DUT is quite sluggish. There are several improvements planned: First is fragmentation support and IPv6, then figuring out how to leverage > 1 core, followed by integration with a routing daemon (quagga / bird) and adding support for ACLs. Maybe IPSec (in the fast path) after that. We'll also need to add support for NAT in the fast path at some point, (people need it, but I loathe NAT.) The goal is > 10Mpps on commodity hardware running FreeBSD with full IPv4/IPv6 routing and ACL. This will also run on Linux and even Windows with some effort. The cool thing about netmap/netmap-fwd is that the host stack is still active, so you still have the full FreeBSD stack running on the same interfaces, and the interfaces configure just like stock FreeBSD. -- Jim ------------------------------------------------------------------------------ _______________________________________________ Bsdrp-users mailing list Bsdrp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bsdrp-users
