I have :-) See the second item in the proposed topics for the Hackaton. We can't use directly DPDK, as it would be a bit mad to implement a layer 4 protocol from scratch. But TLDK provides a (reduced) TCP stack built on top of DPDK, which means we can use the existing TCP transport code with it. Much more feasible for a 2-day hackaton! I've wanted to experiment with that for a long while now (I'm quite active in DPDK as well), just never had the time. Benjamin, PF_RING sounds very interesting as well, please feel free to add it to the list. Bear in mind that I started compiling that list just to throw in ideas that I think would be interesting, so feel free to add as many things as you like. Then when we are there we can chat and decide what to do together. We can work on multiple things in groups, etc etc, nothing fixed in stone. > 2017-10-06 11:18 GMT+02:00 Benjamin Henrion <zoo...@gmail.com>: > > > Hi, > > > > I see in the agenda of the hackaton that there is an item about > > zerocopy kernel API: > > > > http://zeromq.org/event:zeromq-pre-fosdem-hackaton-thu-1-fri-2-feb- > > 2018 > > > > What about PF_RING? > > > > I have used curvetun: > > > > http://manpages.ubuntu.com/manpages/wily/man8/curvetun.8.html > > > > Which can do gigabit encrypted link with an average cpu. > > > > Curvetun uses libsodium, and PF_RING to speed things up. > > > > I guess PF_RING makes a big difference, and in the case of zmq, it > > should do as well (spends less time in Linux tcpip stack).
