On Cac Function for the Wireless Atm Network
The paper focuses on some difficulties in performing the CAC (Connection Admission Control) function in the case of wireless ATM network with wireless access points controlled by a dynamic TDMA (Time Division Multiplex Access) class protocol. The medium access protocol assumed for the purposes of this paper is MEDIAN [1]. Specific characteristics of this protocol, like frame structure, differen...
متن کاملEquivalent bandwidth characterization for real-time CAC in ATM networks
Many call admission control schemes for ATM-type networks are based on the concept of eeective bandwidth (EB). Most such schemes focus on the cell loss rate as the exclusive QoS metric and therefore base their EB on cell-loss rate approximations. We use simulation data to train an adaptive logic network (ALN) to estimate cell loss and delay; these estimates can then be used to compute eeective ...
متن کاملLearning Algorithm for CAC Adjustment in ATM Networks
We propose an algorithm for measurement based CAC adjustment in ATM networks. The algorithm was derived under requirement that it is applicable to ATM switches without proprietary solutions. For this reason the algorithm is fed by simple cell loss measurements. Based on this measurements the CAC overbooking factors are updated once a day. The updates are optimized based on the history of the me...
متن کاملHierarchical CAC and routing in IP/ATM networking
In the context of an ATM access and transport network, carrying guaranteed quality (CBR, rt-VBR) services as well as IP datagrams (as ABR or UBR traffic classes), we consider the joint problems of Call Admission Control (CAC), bandwidth allocation and routing.. The presence of distributed access multiplexers is assumed, which are both geographically dispersed (e.g., at the user premises) and hi...
