    Dynamic traffic management (DTM) is described. The overall system architecture and data flow, routing, and congestion control are addressed. The main design considerations are reviewed, focusing on the update cycle, protective allowance, multiple alternate routes, congestion-control thresholds, and algorithm extensions. The immediate benefits that automation and near-real-time responsiveness entai... View full abstract»

    Schemes that do not explicitly use much information about the state of networks are briefly surveyed, with the focus on dynamic alternative routing (DAR), a simple but highly effective routing method currently planned for the British Telecom Network. State-dependent routing and how some of the methodology also has bearing on the control issue are discussed. The problem of dimensioning a network th... View full abstract»

    The nature of the traffic-routing problem is described, and early studies of state-dependent routing are noted. A state-dependent scheme seeks to route each call so as to minimize the risk of blocking future calls, and thus responds to the current state of the network on the basis of certain assumptions about future traffic demands. State-dependent routing is considered as a Markov decision proces... View full abstract»

    Major issues that should be examined in evaluating the performance of networks with dynamic routing are reviewed. The characteristics of international 24-h traffic profiles are examined, and proposed dynamic routing schemes are described. Gain allocation principles are discussed, and results on circuit savings and fault tolerance of international dynamic routing networks are outlined.<> View full abstract»

    The advanced techniques presently used by AT&T to manage traffic flow in its Worldwide Intelligent Network are described. The role of traffic network management strategies is reviewed, and the scope and routing plan of the AT&T Worldwide Intelligent Network are characterized. Three examples of modern protective controls are considered: selective trunk reservation, hard-to-reach process, and select... View full abstract»

    The objectives of network management control are outlined, and two categories of control are defined: network traffic controls and network configuration controls. Network traffic controls are further classified into traffic volume controls and routing controls, and advanced techniques for achieving each of them are examined. Two classes of methods for specifying the amount of traffic to be control... View full abstract»
