A Novel ATM Traffic Scheduler for Real-Time Multimedia Data Transport with Improved Packet Level QoS

چکیده
In this paper, we propose an efficient scheduling scheme called Multi-layer Gated Frame Queueing (MGFQ) for real-time traffics over ATM networks. ATM switches equipped with function of MGFQ which employs only one set of FIFO queues can provide real-time multimedia communication with a wide range of QoS requirements. In addition, a hybrid design which combines MGFQ scheme with Age Priority Packet Discarding (APPD) scheme is proposed to enhance packet level QoS. The simulation results show that the cell level performance as well as the packet level QoS can be improved simultaneously when applying this hybrid design.

Design and Simulation of an Efficient Real-Time Traffic Scheduler with Jitter and Delay Guarantees
In this paper, we propose a framework for real-time multimedia transmission in asynchronous transfer mode (ATM) networks using an efficient traffic scheduling scheme called multilayer gated frame queueing (MGFQ). MGFQ employs only one set of FIFO queues to provide a wide range of QoS for real-time applications. We also propose special cell formats for real-time multimedia transport and a hybrid...
متن کاملA Novel Cell Scheduler with QoS Guarantee for Services in ATM Networks∗
Real-time services, including constant bit rate (CBR) and real-time variable bit rate traffic (rt-VBR), have become increasingly important owing to the rapid proliferation of multimedia applications. A cell multiplexing method capable of handling real-time traffic should satisfy related quality of service (QoS) requirements, including cell transfer delay (CTD), cell delay variation (CDV) and ce...
متن کاملImplementation Of Modified Fuzzy Priority Scheduler For MANET And Performance Analysis with mixed Traffic
In this paper, we investigate the performance of a fuzzy based Priority Scheduler in wireless Adhoc networks, with real time traffic under varying channel conditions. An Adhoc network is composed of mobile nodes connected by wireless links without any preexisting infrastructure. The network’s dynamic topology poses challenging problems for QoS routing. Hence a scheduling discipline can be used ...

The exploding growth of World Wide Web applications in recent years has overwhelmed the internet with multimedia traffic. A future performance concern is to keep pace with the quickly growing bandwidth requirements. IP over ATM is a way to relax such requirements. It provides a hybrid approach to support both layer 3 software forwarding and layer 2 ATM hardware switching. A switched virtual con...
متن کاملImproved WWW Multimedia Transmission Performance in HTTP/TCP over ATM Networks
Transmission control protocol/Internet protocol (TCP/IP) is the de facto standard of the networking world. It dynamically adjusts routing of packets to accommodate failures in channels and allows construction of very large networks with little central management. But IP packets are based on the datagram model and are not really suited to real-time traffic. In order to overcome the drawbacks, a ...
