Key challenges in distributed management of broadband transportnetworks

Significant attention has been focused on establishing a framework of standards and generic guidelines for a layered, distributed approach to network management for broadband transport networks. Initial field deployment trials based on these efforts, using SNCs (subnetwork controllers) or EMs (element managers), have just begun. The paper outlines early distributed management applications that are being considered for deployment in the 1995 time frame. The focus is on the key challenges that must be addressed in realizing initial field deployment of distributed broadband management applications
