Inside of an SDN “Island” • 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: • IF: there is a match in the OF pipeline on the packet-in then; match + action. • 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.

Hardware/Software –(Hardware Reference Slide) • "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_normalsupport. • 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.
