Hi all, I'm Huhnkuk at KISTI/Caltech. I'm supposed to give a talk on the NSI canference call of Feb. 12. Attached is a file to be presented and an abstract is below. ===================================================================================================== In this talk, we attempt to outline design issues and challenges for cooperative protection management for guaranteed user-driven VC(Connection) services on NSI Extension. In addition to that, we investigate management information flow mechanisms required for per-domain and end-to-end protection service in a user-driven manner, in order to serve as a basis for the key challenge of how to monitor a global network and primary/backup VC data plane state transition and coordinate transport paths in component domains. ===================================================================================================== Hope that helps you to understand a seamless protection chain service in a user-driven manner on NSI extension. Thanks ! Cheers Huhnkuk
