OIF Kicks Off 2 Projects Focused on 100G

The Optical Internetworking Forum (OIF) is starting two new 100G projects.


The first addresses the interoperable processing of Optical Transport Network (OTN) streams over a packet switch fabric. The convergence towards OTN as the primary transport protocol and the predominance of packet traffic lead to a need to switch ODUk/ODUflex in a Packet Fabric environment. The "OTN over Packet Fabric Protocol" project aims to develop a common protocol for switching ODUk/ODUflex data and timing through a packet fabric to ensure interoperability among framer and fabric devices. By defining a packetized ODUk/ODUflex format, true convergence is enabled as both packet and Constant Bit Rate (CBR) OTN signals can be switched by a common fabric within an Optical Transport Platform (OTP).


The second project addresses the important issue of thermal management at the faceplate of an optical communication system given the trend towards ever increasing port density coupled with the increased power consumption necessary to support higher data rates.



"The industry is seeing a trend toward converged packet optical transport as transport network rates increase to 40G/100G," said Dave Stauffer, of IBM and the OIF's Physical & Link Layer Working Group chair. "This leads to a growing need for interoperability between devices processing OTN clients and a converged OTP. A converged OTP may also lead to a more cost-effective approach."

In addition, the OIF's Physical Layer User Group will develop a white paper elaborating on the need and solutions to improve thermal management at the faceplate that support the trend of increasing power densities.
