3 OpenFlowSwitch.org GENI Aggregate Manager GENI Clearing House College Campus Network College Campus Network OpenFlow Protocol

4 OpenFlowSwitch.org Staged Approach 1. Define OpenFlow feature 2. Add OpenFlow to commercial switches and APs 3. Deploy at Stanford 4. Integrate with GENI Clearing House 5. Deploy on many college campus networks 6. We all create lots of open-source software so researchers can build on each other’s work (We’re part-way into Stage 2)

5 OpenFlowSwitch.org OpenFlow Basics

6 OpenFlowSwitch.org OpenFlow Basics (1) Rule (exact & wildcard) ActionStatistics Rule (exact & wildcard) ActionStatistics Rule (exact & wildcard) ActionStatistics Rule (exact & wildcard) Default ActionStatistics Exploit the flow table in switches, routers, and chipsets Flow 1. Flow 2. Flow 3. Flow N.

7 OpenFlowSwitch.org OpenFlow Basics (2) Rule (exact & wildcard) ActionStatistics Small number of fixed actions e.g. unicast, mcast, map-to-queue, drop Extended via virtual ports e.g. tunnels, encapsulate, encrypt As general as possible e.g. Port, VLAN ID, L2, L3, L4, … As wide as possible Count packets & bytes Expiration time/count

12 OpenFlowSwitch.org Let’s see an example…

13 OpenFlowSwitch.org HP  Experimental feature on ProCurve 5400-series  144-ports of 1GE, hardware forwarding  OpenFlow added by HP Labs and ProCurve group  In 23 wiring closets in CS Building at Stanford Praveen Yalagandula Jean Tourrilhes Sujata Banerjee Rick McGeer Charles Clark

14 OpenFlowSwitch.org NEC  Experimental feature on IP8800 series router  24-ports of 1GE, 2-ports of 10GE, hardware forwarding  OpenFlow added by NEC team in Japan  NEC announced plans for OpenFlow products  Deployed at Stanford and in JGN2plus in Tokyo Hideyuki Shimonishi Jun Suzuki Masanori Takashima Nobuyuki Enomoto Philavong Minaxay Shuichi Saito Tatsuya Yabe Yoshihiko Kanaumi NEC/NICT Atsushi Iwata

15 OpenFlowSwitch.org Juniper  OpenFlow added to Junos SDK  First platform: MX-480 carrier class Ethernet  24-ports 10GE or 240-ports 1GE  Hardware forwarding  Deployed in Internet2 in NY and at Stanford Umesh Krishnaswamy Michaela Mezo Parag Bajaria James Kelly Bobby Vandalore

16 OpenFlowSwitch.org Cisco  Experimental feature on Catalyst 6509  Software forwarding  Deployed at Stanford Flavio Bonomi Sailesh Kumar Pere Monclus

17 OpenFlowSwitch.org Nicira Martin Casado Scott Shenker Teemu Koponen Natasha Gude Justin Pettit  Created NOX controller  Available at (GPL)http://NOXrepo.org  Deployed at Stanford Controller

18 OpenFlowSwitch.org Using Enterprise GENI for research
