College Campus Network Staged Approach 1. 2. 3. 4. 5. Define OpenFlow feature Add OpenFlow to commercial switches and APs Deploy at Stanford Integrate with GENI Clearing House Deploy on many college campus networks 6. We all create lots of open-source software so researchers can build on each others work (Were part-way into Stage 2)
OpenFlowSwitch.org OpenFlow Basics OpenFlowSwitch.org OpenFlow Basics (1) Exploit the flow table in switches, routers, and chipsets Flow 1. Rule (exact & wildcard) Action Statistics Flow 2.
Default Action Statistics Flow N. OpenFlowSwitch.org OpenFlow Basics (2) Rule (exact & wildcard) Action As general as possible e.g. Port, VLAN ID, L2, L3, L4, As wide as possible
Statistics Count packets & bytes Expiration time/count Small number of fixed actions e.g. unicast, mcast, map-to-queue, drop Extended via virtual ports e.g. tunnels, encapsulate, encrypt OpenFlowSwitch.org OpenFlow Basics (3) Controller OpenFlow Switch specification OpenFlow Switch
