Methods for routing, performance management, and service problem relief in Datakit networks

A set of models developed to do traffic engineering, i.e., routing, performance analysis, and service problem relief, for data networks that use AT&T´s Datakit virtual circuit switch is described. Software tools have been developed based on these methods and integrated into a comprehensive traffic engineering system called traffic administration and management system (TAMS). In addition to the methods, how the capabilities of this traffic engineering system will fit into various key functional areas of network management, such as performance management and network planning, is described
