I've been using the script successfully for the past few days, so Acked-by: Daniele Di Proietto I have a few comments (I feel ridiculous being so picky about a python script, so feel free to apply/ignore them). Would we care about making it run also with python3? Only 3 changes are required (se

2015-04-24 Thread Ethan Jackson
When doing OVS performance testing, it's important to have both realistic traffic traces and OpenFlow pipelines on which to evaluate prospective changes. As a first step in this direction, this patch adds a python script which generates an OpenFlow pipeline intended to simulate typical network vir
