McKeown Group OpenFlow v1.0Weekly Status Report

Week5/2011(02/02 Wed—02/08 Tue)

Status Update

WIRED and DEMO NETWORK• No updates

2

Status UpdateWIRELESS• 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.
