OIF Finalizes IAs for 100G Modules and Control Plane Logging/Auditing

The Optical Internetworking Forum (OIF) finalized two implementation agreements (IAs) addressing the key electro-mechanical aspects of a 100G long-haul transmission module and control plane logging and auditing.

The OIF 100G Long-Haul DWDM Transmission Module IA provides component and system suppliers with a modular interface approach. Key aspects include; module mechanical dimensions, electrical connector and pin assignment, module hardware signaling pins, high-speed electrical characteristics, power supply, power dissipation, and management interface.

"We expect this to be the industry successor for the 300 pin MSA," said Karl Gass, the OIF's Physical and Link Layer Working Group vice chair. "This design provides for higher density placement on host line cards with a higher speed data and advanced management interface."

The OIF Control Plane Logging and Auditing with Syslog IA defines the protocols, record types, data structures, and fields for log files generated by a Network Element (NE). It also addresses controlling and securing the generation, transport, and storage of log data to provide a flexible logging capability for the OIF's User Network Interface (UNI) and External Network to Network Interface (E-NNI). Version 1.1 of the IA fully conforms to the IETF standards for Syslog and precisely defines a general set of log messages for the OIF's control plane protocols.

"The ability to log signaling and routing messages as they traverse multiple UNI or E-NNI interfaces adds a useful and effective way to help assure correct and secure operation of the signaling and routing entities," said Doug Zuckerman, of Telcordia Technologies and the OIF's OAM&P Working Group chair. "This is an important tool to help carriers deploy and operate control plane technology in their networks."

Both IAs are on the OIF's website.

  • In June 2010, the Optical Internetworking Forum (OIF) kicked off two new 100G projects. The first addresses the interoperable processing of Optical Transport Network (OTN) streams over a packet switch fabric.
    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.
