1. McKeown Group OpenFlow v1.0 Weekly Status Report Week5/2011 (02/02 Wed—02/08 Tue) 1

2. Status Update WIRED and DEMO NETWORK No updates 2

3. Status Update WIRELESS Necsw3 was removed for testing NEC controller (Helios) Still spiky flow setup time – Two cases (see slides 5-9) SNAC: Slow down and flow setup time goes up to seconds. Lasts few minutes. Switch: Occur randomly (does not last). Add few 100ms of seconds. – Switching to product firmware doesn’t change the figure. 3
