McKeown Group OpenFlow v1.0Weekly Status Report

Week4/2011(01/26 Wed—02/01 Tue)

1

Status Update

WIRED NETWORK• hpsw3 was removed for preparing to test BigSwitch

controller (last Thur)

DEMO NETWORK• All demos working

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.

3

Performance Summary

WIRED NETWORK• Abnormal flow arrival rate for HPSW3

– Still debugging

WIRELESS NETWORK• Spiky flow setup time

– Still debugging

Measured metrics 　 (no change)

• Switch Statistics– Active flows– Flow injection rate– CPU usage– Traffic volume

• Network Performance– Flow setup delay– E2E RTT– E2E packet loss rate– wget delay
