Routing and bandwidth management options in high speed integrated services networks

The authors present various options of routing architectures for asynchronous transfer mode (ATM) networks based on currently developed user-network interface (UNI) protocols. The bandwidth reallocation, routing updating, and call connection levels are distinguished. The functions of the corresponding procedures are defined with respect to the traffic performance requirements and are related to the ATM protocol layers. An architecture of the ATM node is briefly discussed.<<ETX>>
