  OIF Members Tackle SDN, 400G Interconnect and More

FREMONT, Calilf. -- May 13, 2013

The Optical Internetworking Forum members defined a number of new projects for
both Networking and Physical and Link Layer (PLL) technologies in their
quarterly meeting last month. The OIF’s networking group continues to work
with the Forum’s Carrier members to define requirements for Transport SDN. As
part of this activity, work has started on an SDN Framework document to better
focus the conflicting and confusing requirements that vary in the industry for
Transport SDN. Separately, plans for an SDN networking interoperability
demonstration are currently in the works for 2014 and will showcase technology
outlined in the SDN Framework document. On the PLL side, two projects
addressing Thermal Interface requirements and CFP2 Coherent Optics Transceiver
module were also started. Members also completed and approved the Next
Generation Interconnect Framework white paper as well as implementation
agreements on Multilink Gearbox and a Multilayer Amendment for E-NNI.

"The OIF is working on defining a framework for the industry to clarify the
interfaces required in the Transport SDN ecosystem, leveraging input from
carriers,” said Jonathan Sadler, Tellabs and the OIF’s Technical Committee
chair. “In addition, the OIF is advancing work in 100G interconnect and has
completed implementation agreements that focus on technology from past
interoperability demonstrations. The Forum continues to drive technology
efforts that are necessary for providing higher speeds and lower costs for the

The OIF will be presenting an overview of the Carrier SDN Requirements and SDN
Framework project as well as the newly completed 400G/1T Next Generation
Interconnect Framework whitepaper in a workshop at the Light Reading
Packet-Optical Transport Evolution 2013 in New York City on May 14^th at 8:15
am. Presenting on behalf of the OIF are OIF president Vishnu Shukla of Verizon
and Dave Brown of Alcatel-Lucent and an OIF board member.

“A consensus has been reached by Forum members agreeing that development work
must begin to address next generation data rates for future systems and
determine what interconnects should have defined interoperability
requirements,” said Nathan Tracy of TE Connectivity and the OIF’s Technical
Committee vice chair. The Next Generation Interconnect Framework white paper,
which addresses technical challenges for the next generation higher data rates
and higher throughputs required for systems operating beyond 100G and
identifies applications spaces where OIF development work may be required,
will be presented at next week’s Light Reading Conference. The presentation
also shares the results of recent interoperability tests on the OIF
CEI-28G-VSR draft implementation agreement conducted by the OIF.

New Projects

A new project on Thermal Management will specify a module-type agnostic
thermal interface between an optical module and a host bringing consistency
and standardization to the industry. A second new project focuses on a
Coherent Optics Transceiver module in a CFP2 form factor and will help
maximize faceplate density and minimize first install costs on metro/regional
line-side transport or switching platforms.

Completed IAs

The Multi-link Gearbox 2.0 implementation agreement defines a 4x25G lane
configuration comprised of 20 MLG lanes and an 8x25G lane configuration
comprised of 40 MLG lanes. Both are configured to carry multiple 10GBASE-R
signals or a single 40GBASE-R signal. This IA will serve as an important
infrastructure element in high rate systems.

A second IA, the Multilayer Amendment defines generic signaling and routing
extensions to the OIF’s E-NNI 2.0 implementation agreement in support of
multilayer networks. Based on technology demonstrated in past interoperability
tests the Multilayer Amendment provides the ability for the control plane to
determine the lowest cost way to deliver a service using different

About the OIF

Launched in 1998, the OIF is the first industry group to unite representatives
from data and optical networking disciplines, including many of the world's
leading carriers, component manufacturers and system vendors. The OIF promotes
the development and deployment of interoperable networking solutions and
services through the creation of Implementation Agreements (IAs) for optical,
interconnect, network processing, component and networking systems
technologies. The OIF actively supports and extends the work of standards
bodies and industry forums with the goal of promoting worldwide compatibility
of optical internetworking products. Information on the OIF can be found at
