The integrated management for UNI and NMI in ASON

The ASON is a typical client-server network model. Via explicit interfaces between client network and server network, the client users, including UNI-C and NMS, can create an Optical Layer Connection with three schemes. This may arise the problems such as concurrency due to simultaneously accessing the same resources from UNI and NMI. This paper proposes an approach of a middleware component using CORBA-based product. The middleware component performs to define the ownership and access rules for network resources and prove global network topology and status of the network resources to the client users. It screens the difference between NMI-T, NMI-A and UNI and shields the detail of the ASON network protocols. The standardized IDL interfaces ensure that ASON products from different vendors or employing different technologies can interoperate at the common intermediate plane level and make the implementation of the management functions more simply and efficiently.
