Status

12/10:

• Phase 0: success
• Phase 1.0 (running NOX): success
• Phase 1.2: success -- routing does exact match, including ARP L3 fields. (ARPs didn't get through until KK fixed the code to set L3 fields on ARP).

Components and Dependencies

1. OpenFlow reference implementation
2. NOX:
   • depends on openflow ref
   • need wireline compatible version
3. FlowVisor:
   • depends on openflow ref
   • ETA Friday (?)
4. Netfpga:

OpenFlow v1.0 Test Network

Move to OpenFlow v1.0 test network description page.

Phase 0 : Single switch

• Success
• Single soekris box in 3.2 closet
• controller from openflow reference implementation
• move Brandon (others?) over to it
• Start Monday 12/8 (??)

Phase 1 : Test Nox + Most features

• Add 2nd soekris box in 3.3 closet, physical wire that connects to 3.2
• Replace controller with NOX, initially running just routing (implicitly discovery, etc.)
• Move Masa over
• test slicing in an offline testbed (T-labs los altos)
• Phases 1.x might be able to happen in parallel

Phase 1.0 : Run NOX

• Done

Phase 1.1 : Test flow cookies

• modify NOX routing module to set/test flow cookie Done

Phase 1.2 : Test arp l3 matching

• setup arp proxy and NOX module that forwards all arp for a certain subnet to it
• NOX uses exact match so IP in ARP must work for routing to work Done

Phase 1.3 : Test specify port in port stats

• test via dpctl Done
• consider modifying envi to expose this

Phase 1.4 : Test match on ToS bits

• test with iperf (to set ToS for different packets) and dpctl (to set flows)
• Need to add ability to specify IP ToS bits to dpctl (Glen: end-of-week)
• Install static flow table entry that sends non-ToS packets to a particular port
• Only packets with ToS set will be sent to controller and thus routed

Phase 2 : Deploy slicing

• integrate FlowVisor
  • add a slice for iperf to test slicing
• add soekris switch in flash lab
• move (some?) APs over
• move all rest of lab over to 1.0 switches

Phase 3 : Deploy on hardware

• blocking on openflow support for HP, NEC
• deploy 1.0 on hardware
