Re: [vpp-dev] [Bug] VPP crashes using deterministic CGN

Hi, Patch is not merged in master branch, so your 18.10 build probably doesn't contain fix unless you apply/download patch manually (git review -d 14106). Matus From: arsalan.sag...@xflowresearch.com Sent: Monday, August 13, 2018 7:50 AM To: Matus Fabian -X (matfabia - PANTHEON TECHNOLOGIES at

Re: [vpp-dev] Overlapping IP/subnet support on base/vlan interface

Hello, I have checked the latest code in master branch and confirm ” VPP does not support multiple interfaces in the same subnet” is still true. And I can understand the commit https://gerrit.fd.io/r/#/c/8057/ is to expand the check of overlapping subnet to all interfaces in the same table/VRF.

Re: [vpp-dev] Regarding CLI command parsing

Try this in mycmd: u8 * line; if (unformat (input, "%U", unformat_line, &line)) process_line; Note that line will be a true u8 * vector: no null-termination. If you need null termination: vec_add1 (line, 0); Remember to vec_free(...) it unless you're planning to keep it. HTH... Dave -

Re: [vpp-dev] timing_wheel or tw_timer

The tw_timer implementation is extremely fast. We routinely test it to 60 million concurrent timers, the number required to bring up 10M TCP sessions. Given a 500ms granularity, we have: max range = 86400 (secs/day) * 2 (clock ticks/second) = 172800 slots. A 2-ring, 512 slots/ring geometry would

[vpp-dev] Regarding CLI command parsing

Hi, I am relatively new to this and trying to learn the art of using format/unformat. My requirement is that if my command is "mycmd" followed by some string (which may have spaces in it), then I should be able to read the entire string up to the \n character typed by the user. Eg. if the command

[vpp-dev] timing_wheel or tw_timer

Hi, I need to implement per session timers with about 500ms granularity. Maximum timer range can be up to 24 hours. Should I use the timing_wheel (like BFD does) or one of the tw_timer's? And what is main difference between the timing_wheel and the tw_timer anyway? Thanks Andreas -- -- Dipl.-
