Hi,

Yes, DPDK seems can not help with codec conversion (transcode). But , DPDK will improve the packet throughput. And maybe ,just maybe, decrease the delay . And the biggest benifit from DPDK is you will get more cpu time for other task, such as "transcoding"( traditional nic work mode will eat much cpu on high traffic ).

And DPDK is now only work for Intel NICs .

Basically , Freeswitch is an "network application" , SO ,why not have an "DPDK" version. Much helpful for high performance.

I think DPDK cannot do RTP streaming or codec conversion.

Hi, guys

Is there's any plan to develop a "DPDK Freeswitch version" ? DPDK is really a big improve of network .

Just mu 5ct because I haven't spent much time with DPDK, but also my impression is that is useful when doing packet routing rather than application level complex processing (e.g., handling rtp for dtmf, transcoding or mixing streams). Only maybe make sense for media passthrough mode with freeswitch, but I guess it won't bring much more performance benefits at the expense of losing all media processing capabilities. If you only need to collect the rtp streams to a single point, using kernel forwarding (iptables) rules can be an alternative solution to cope with more traffic (rtpengine can do that, controlled by kamailio sip proxy).

Cheers,
Daniel
