OpenFlow Path to Internet2 Stitched via KYRON

• The network infrastructure objective is to provide both OpenFlow forwarding and legacy packet forwarding via the FIB in the same physical network.

• If code and/or hardware support is not available for the existing hardware in the campus core, path isolation will be done with L2 Vlans and L3 MPLS/VPNs.

• OF Controller(s) and GENI racks are distributed in each switch block.

• Hardware from the distribution down will be replaced if it cannot be retrofitted with new software with OF support.

• Hybrid Forwarding logic:1. IF: there is a match in the OF

pipeline on the packet-in then; match + action.

2. Else: No match is found in the controller from the packet-in event, the flow is passed to the “normal/local” FIB for L2/L3 packet forwarding via the native FIB.

GENI Research, Faculty and Staff Contacts

• "I think we'll see a Balkanization where the traditional SDN interface will be more suited for research and educational type uses, and where applications like network virtualization are customer and product focused,” --Martin Casado

• GENI Racks:• On or coming to market Cisco, IBM, HP and Dell. HP racks are deployed today.• Edge Hardware:

– POE – POE limits hardware vendor selection greatly. Most OF 1U enabled switches are Trident chipset based TOR switches missing POE.

– Non-POE switches are only candidates in the Data Center.– OpenFlow v1.0 agent.– Candidate HW Platforms: HP, Pica8, Cisco hardware(leverage existing 6509), (Dell still stealth split-data

plane), Brocade and Juniper. Hardware reviews begin in January 2013 since many announcements are slated for Q1.

– Track VC startups as their products become GAin 2H2013. Particularly data center and Optical with hardware and channel strategies. Plexxi, Adara, Plumgrid.

• Distribution:– 10Gb Uplinks.– OpenFlow v1.0 agent.– Hybrid OF_local and/or OF_normal support. – Native FIB and Flow table pipeline interaction is vital for quality hybrid support.– LSR Roadmap Support– Candidate HW Platforms – Juniper MX, Brocade MLX and existing Cisco 6500.– Whitebox PE nodes are attractive but unrealistic within 1H 2013.

• KY Regional Network and I2 Connector:– Openflow enabled Junos image for RON nodes. Junos 12.0 has a beta image 1Q2013 that is GA in Q4.

• Controllers/SW - Needs Research for GENI Integration:– Candidate OF controllers: Cisco Alpha, HP Q1, Big Switch Q1, Floodlight- Open Source, RYU (NTT).– NOS – Open vSwitch as OVSDB firms and Vmware control plane strategy is articulated.– OVS is the base of many vendor OF agents. OVS v1.3 support is in progress.
