Book excerpt: A unified approach to the analysis and design of traffic management controls in circuit switching, packet switching, LAN, MAN, narrowband, and broadband integrated services networks is presented in this volume, along with an in-depth survey of management and control schemes which are used to allocate network resources to different users in a dynamic environment, meeting user performance requirements. Stress is placed on the role of measurements and network information patterns. Also included is a presentation of control procedures being insensitive to detailed values of control parameters and exact statistics of offered traffic, and performance analysis of automatic network management controls under nonstationary load conditions.
