A Hybrid Admission Control Scheme for Broadband ATM Traffic
نویسنده
چکیده
Link admission control (LAC) in broadband ATM networks is based on evaluation of expected traffic performance. The traditional LAC approach relies on approximate analytical performance models, and can lead to an over controlled network. This paper presents a hybrid LAC scheme which uses a multi layer perceptron (MLP) to refine the performance estimate of a traditional analytical approximation. An accurate but complex traffic performance model is used to derive MLP target data. The numerical results show that the MLP can improve the bandwidth efficiency.

A Hybrid Medium Access Control for Convergence of Broadband Wireless and Wireline ATM Networks
In this paper, we propose a hybrid medium access control protocol for supporting broadband integrated services in the wireless ATM networks. The integrated services include CBR, VBR and ABR traffic varying from low bit-rate to very high bit-rate. The proposed protocol is an excellent compromise of contention, reservation and polling access techniques based on the dynamic TDMA system. Extensive ...
متن کاملA Review of Connection Admission Control Algorithms for ATM Networks
The emergence of high-speed networks such as those with ATM integrates large numbers of services with a wide range of characteristics. Admission control is a prime instrument for controlling congestion in the network. As part of connection services to an ATM system, the Connection Admission Control (CAC) algorithm decides if another call or connection can be admitted to the Broadband Network. T...

Connection Admission Control (CAC) is a preventive congestion control mechanism and it is essential for providing Quality of Service (QoS) requirements for calls established over ATM. The strategies for CAC in an ATM network can be classij?ed into two categories: measurement-based CAC and traffic descriptor-based CAC. Both categories have their advantages and disadvantages. This paper proposes ...

متن کاملA simulation study on the performance of integrated switching strategy for traffic management in ATM networks
Designing effective congestion control strategies for broadband networks is known to be difficult because of the variety of dynamic parameters involved such as link speeds, burstiness of the traffic, and the distances between traffic sources and switching nodes. We propose a traffic management scheme, which is insensitive to the propagation delay between the sources and switching nodes. We achi...
