From b6454edc8d9cb7294cd2b63feb9a3b61fde35906 Mon Sep 17 00:00:00 2001 From: Jing Zhang Date: Tue, 11 Apr 2017 15:24:22 -0400 Subject: Add a new runner to test end-to-end fast data path This runner caters testing fast host data path (e.g. SRIOV) plus fast VM data path (VM running pktgen-dpdk). It is implemented as a new flavor of the existing Iteration runner. (1) Add a new SLA action rate-control (2) While the SLA target is not met, reduce packet rate until packet loss target is met.
