Abstract
Huge increase in switching and transmission capacity coupled with a need to the integration of the services has lead to the development of the asynchronous transfer mode (atm), a standard for the transport of all telecommunication services over a common network.
This thesis describes a method for admission control in atm network, which is a mechanism by which the network determines whether a connection request should be accepted, and is a basic tool for ensuring the qos guarantees.
Unlike telephone networks. Call admission in a multiservice network is not straightforward. A number of problems arise in performing admission control. For example, the estimation of resource requirements for new connections requires information such as the traffic characteristics and current system status, both of which are not readily available.
