Internet2 readies 100G OpenFlow SDN for Big Data
At this week's Summer 2012 ESCC/Internet2 Joint Techs meeting at Stanford University in Pal Alto, Calif., 300
Internet2 network engineers will collaborate to define the technologies and capabilities that will bring about the
Innovation Platform, which Internet2 touts as the U.S.'s first open SDN network. To date, more than 20 Internet2
member universities and regional networks have asked to become collaborators in piloting the platform, the
Access links will be 10G and 100G Ethernet. Internet2 has already written an OpenFlow-based SDN application for
Layer 2 VLAN provisioning.
THE BUSINESS NEED: What are the
killer apps for software-defined networking?
The latest infrastructure additions are 100G Ethernet OpenFlow-enabled routers from Brocade and Juniper at 35 to
45 sites. Brocade's MLX and NetIron systems, and Juniper's MX series routers will enable programmatic control of
the Innovation Platform from an open source NOX SDN
controller to facilitate scale and intelligent service delivery, according to Internet2.
As an SDN, the Innovation Platform is designed to advance education, university businesses, and global Big Data
collaborative research outcomes to enable new research initiatives and new cycles of global economic development,
according to Internet2. The programmability aspect will enable further innovation in application development across
a community of developers as well, the organization asserts, by allowing network 'slicing,' or the ability to
isolate subsets of the network for application development.
It may also allow Internet2 to build an SDN "application store" to allow developers to offer new applications on
a trial basis to the research and education community.
"The Internet2 community sees software-defined networking as much of the same transformative opportunity that we
saw with the original Internet," says Rob Vietzke, vice president of network services for Internet2. "We're making
a fairly big investment in building this new nationwide SDN environment as a platform for software
For Big Data, the Innovation Platform will allow member institutions to keep pace with the exponential growth in
massive datasets generated by scientific research conducted by collaborative researchers in U.S. labs and
universities. But Vietzke also expects advances similar to those in the university environments that created Google
and Facebook to possibly emerge from use of the Innovation Platform.
The Innovation Platform was proposed earlier this year by
Internet2 as a complement to its NDDI project and the NSF's GENI program. At
that time, it was
touted as a new $96.5 million national-scale SDN owned by the research and education community.
"A multidomain, wide-area view of what SDN can do is unique," Vietzke says. "If you thick back to the early era
where the network stack was open, and folks on campus started out with this thing call TCP/IP, and decided they
needed this thing called DNS, and came up with this thing called mail transport -- all of that was in an era when
networking and the protocol stacks were open and folks were able to innovate. We're hopeful that this 100G backbone
with 30-plus nodes across the country doing SDN will provide that same kind of testbed."
The National Telecommunications and Information Administration's Broadband Technology Opportunities Program
helped fund Internet2's network upgrade in support of the U.S. Unified Community Anchor Network (UCAN) project.
UCAN enables advanced networking capabilities for more than 200,000 of the country's "anchor" institutions,
including libraries, hospitals, K-12 schools, community colleges and public safety organizations.
Such capabilities include HD and multicast video distance learning and telemedicine applications, among others,
which are not possible using consumer-grade Internet service, according to Internet2.
Vietzke says he expects one or more other "major players" with OpenFlow-enabled products to be announced for the
Innovation Platform in the near future.
