Abstract

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 each other (e.g., the two basic traffic control functions, CAC (Connection Admission Control) and UPC (Usage Parameter Control), are necessary to guarantee the desired broadband network performance). Therefore, an automated management is being increasingly demanded. The need for such management is also highlighted in large distributed systems to deal with the complexity inherent to the very large number and diversity of the resources to be managed. This paper presents an approach for ATM management automation based on a policy management activity applied in a uniform and recursive way. The approach is applied to VCC and VPC management emphasizing a real-time management of an ATM switch which is the basic network element of Broadband-ISDN.
