Total Network Data System: Network management

This paper describes steps that have been taken to respond to the need for better network management in the evolving telecommunications network. In near-real time, network management functions recognize the onset of an overload and respond with control actions that change normal call routing through expansive or restrictive traffic controls. Emphasis is being placed on improved automatic controls that are built into the network and its switching systems. Advances in manual controls and real-time network performance monitoring have been accomplished through the introduction of computer-based systems that provide network managers with preprocessed network performance data and with the ability to intervene in problems that require human judgment.
