Contribution Number: OIF2001.055 Working Group: Architecture, Signaling, OAM&P TITLE: Detecting and correlating external path-related faults and degradations by extending LMP between OXC and DWDM SOURCE: Sudheer Dharanikota (sudheer@nayna.com) Raj Jain (raj@nayna.com) Jay Shah (jay@nayna.com) Nayna Networks Yong Xue (yxue@uu.net ) UUNET/Worldcom DATE: January 22, 2001 ABSTRACT: The need for faster detection and restoration of faults and degradations is essential in the optical networks due to the amount of traffic being carried by them. This calls for tighter control on the detection and reporting mechanisms. In this document we propose some such extensions that can be made to the LMP to run between the DWDM and OXC. This proposal is to extend [2] and to streamline the needs for such a protocol. Notice: This contribution has been created to assist the Optical Internetworking Forum (OIF).
