1 Stanford Clean Slate Program Nick McKeown Faculty Director Guru Parulkar Executive Director

2 Stanford Clean Slate Program Two questions: 1. With what we know today, if we started over with a clean slate how would we design the Internet? 2. How will the Internet be in 15 years? Clean slate is a research approach, not a deployment strategy

3 Our Approach Build Platforms for Innovation Enable a large community to bring about change from the ground up Team: 15 faculty, 40 graduate students Clean Slate Lab: Guido Appenzeller + team of 6 engineers Sponsors: NSF, NEC, DT, Cisco, DoCoMo, Ericsson, Xilinx

12 OpenFlow

13 Our Approach 1. Define the substrate Define the OpenFlow feature Add to commercial switches, routers, APs and basestations 2. Deploy on college campuses 3. Deploy in national networks 4. Deploy in enterprise networks OpenFlow Puts control into the hands of users, owners and applications Allows continued evolution of the network

14 Step 1: Remove all intelligence from datapath Operators, users, 3rd party developers, researchers, New function!

15 Step 2: Cache decisions in dumb datapath If header = x, send to port 4 If header = y, overwrite header with z, send to ports 5,6 If header =?, send to me Flow Table

18 OpenFlow Controller OpenFlow Protocol (SSL) Control Path OpenFlow Data Path (Hardware)

19 OpenFlow Deployments Clean Slate Laboratory Stanford Deployments Wired: CS Gates building, EE CIS building, EE Packard building (soon) WiFi: 100 OpenFlow APs across SoE WiMAX: OpenFlow service in SoE Other deployments Internet2 (NetFPGA switches) JGN2plus, Japan (NEC switches) research groups have switches

20 Trombone: A national substrate Proposed Goal: Create national OpenFlow Substrate for research community Internet2/NLR and 6 regional networks Extend into 30 college campuses Based on commercial switches/routers running OpenFlow (Juniper, Cisco, HP, NEC)
