    Analysis of ATM Call Detail Records and Recommendations for Standards
    Wang, Xianrui Roger (Virginia Tech, 1999-06-23)
    Data network resource management and capacity planning are critical for network design, operation, and management. Equipment vendors often provide good information for traffic management and control and associated tools, but this information and the tools are based on independent, individual switches or routers rather than the whole network. There is a critical need for tools to monitor general resource usage in a network as a whole. In this research, we develop a toolkit to collect ATM Call Detail Records (CDRs) from two types of ATM switches from IBM and FORE Systems. Data records collected by the toolkit can then be used to assess network resource utilization and traffic characteristics with the objective of predicting future needs, making proper network management decisions, and ultimately, assisting in the ability to provide reliable quality of service (QoS) in the network. In addition, we examine current call detail records and requirements for more comprehensive network management and make recommendations for a standardized CDR.
