Integrated management for IP end-to-end transport services over WDM networks

This paper outlines the initial architectural results of WINMAN, an European research and development project started in July 2000, whose aim is to offer an integrated network management solution for the provisioning and maintenance of IP over WDM end-to-end transport services derived from service level agreements (SLAs). Management requirements for IP over WDM have been identified and a two-tier architecture has been conceived for the system that is intended for proof concept of the WINMAN solution. The first layer contains the technology dependent managers, that is one for the IP technology and another manager for the WDM. These two management systems will interact with existing network element management systems the southbound WINMAN interface. On top of this layer there is a second interface whose purpose is the integration of the above mentioned management systems. This system will be in turn integrated in different experimental test beds and fully tested in real life conditions.
