Automated end-to-end management in ATM networks

ATM network management and ATM traffic control are usually separated: traffic controls are performed automatically by the set of real time algorithms while management tasks are inherently slow and may often involve a human manager. However, network management and traffic control operations interact with each other (e.g., the two basic traffic control functions, CAC and UPC, are necessary to guarantee the desired broadband network performance). Therefore, an automated management system is being increasingly demanded. This paper presents an approach for ATM management automation based on a domain-based structuring of the management activity and the application of a uniform and recursive management model. The approach is applied to virtual channel connection (VCC) and virtual path connection (VPC) management emphasizing a real-time management of an ATM switch which is the basic network element of the B-ISDN.
