An architecture for integrating the wireless services into the network management architecture of future ATM networks is presented. Such integrated communication networks are motivated by an anticipated demand for wireless extension to the future ATM network. First, we briefly propose the AWN Binding Reference Model (ABRM) which can support the mobilities of wireless terminals over ATM networks. Here, we mainly treat the network management architecture related to the call connection and handoff. The proposed ABRM defines a conceptual framework for the creation, deployment, and management of PCS with end-to-end QOS over the ATM network. The ABRM incorporates monitoring and real-time control, management, communication, and abstraction primitives that are organized into five planes: the network and system management (N-plane), the resource control (M-plane), the connection management (C-plane), the user information transport (U-plane) and the data abstraction and management (D-plane). It can be extended as a open signaling architecture which operates on the various backbone networks such as TCP/IP and ATM network.

The authors propose a new method for the modeling and call admission control (CAC) of variable bit rate video source, which come to the front of ATM networks as hot issues nowadays. First, the modeling of video source is accomplished using the three-state Markov chains including the effects of scene change at which the bit rate of video source is abruptly increased. Also, using two AR models, they improve the defects which an AR model has in modeling a video source. In addition, they represent the analytical model of a video source so that a network manager can acquire the information which is very important in managing the entire networks. CAC is accomplished using the previously defined analytical model. A routing manager calculates the cell loss probability of a chosen VP where a new call is connected so that the routing manager decides whether this new call is accepted or not. This calculation is accomplished through the GB/D/1-S queuing system. Using BIA (bandwidth increasing algorithm), they check whether the calls rejected by the routing manager could be accepted if possible. Finally, the applicable procedures to suitable allocate bandwidth to each VP on a link are presented in detail.>
