From ff1f49d9ba97ddfee3229907e3a344503e072578 Mon Sep 17 00:00:00 2001 From: Jan Gelety Date: Thu, 6 Aug 2020 03:34:31 +0200 Subject: Perf: NAT44 endpoint-dependent mode - udp, part I - continuation of https://gerrit.fd.io/r/c/csit/+/26898 as there was reached limit of changes (1000) Jira: CSIT-1711 - udp synthetic profiles w/o data packets - udp cps perf tests, phase I (no special "search cps" KW) Part I means that we are using MRR tests to collect traffic data until there is ready new CPS test type with corresponding algorithm.
