Application of Common Management Information Protocol (Cmip) in Atm Network Bandwidth Allocation System

ABSTRACT Asynchronous Transfer Mode (ATM) of transmission is designed as a Broadband Integrated Services Digital Network (B-ISDN) transfer mode that supports a wide range of traffic classes with diverse flow characteristics. ATM guarantees different quality of service (QoS) demands placed on a network by different services (traffic types). The above powerful feats could be well achieved in ATM network with the application of an efficient and effective network resource management system. This thesis therefore, focused on the application of Common Management Information Protocol (CMIP) in the management of ATM network resources. In this thesis, ATM network resource management system is modelled using CMIP principle. The management system was applied in the allocation of network bandwidth on a real-time basis. The performance of the system was analysed and considered satisfactory.
