Ensuring Intelligent Optical Network Interoperability, Reliability & Performance
Today’s traditional SONET/SDH networks provide high levels of reliability based on mature and stable technologies, however these networks are unsuitable for the impending bandwidth revolution. Intelligent optical mesh networks promise to deliver new levels of optical network scalability, manageability and efficiency.
These new optical transport networks take routing and signaling technologies from the data networking industry and adapt them for use in optical transport networks. While these new technologies bring many benefits to optical networks, they also introduce new risks that threaten to compromise the reliability and performance of a core optical transport network.
New methods are required by equipment developers and service providers for verifying interoperability, reliability, and performance of new optical networking elements before deployment. These new methods are proposed and discussed in this paper.
