A Layered Approach To Network Management Control
Leith H Campbell, H.J. Everitt · 2005
Public telecommunications networks have many supporting operations systems to provide network management functions and operational support. These systems must be coordinated to provide a highly reliable network service and to make best use of network resources. With increasing automation of network control, these systems must evolve to provide total network support. One organizing principle for this evolution is the definition of control layers at which individual control functions are exercised. We describe a proposal for layered control, with particular emphasis on the role of network traffic management. Layering will be a significant study item for the next extensions to CCITT's Telecommunications Management Network (TMN) recommendations.
