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.

"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

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:

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.
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.
