Packet scheduling plays an important role in radio resource management to guarantee QoS of streaming service. In this paper, a novel fast packet scheduling algorithm called MAF (Minimum Ahead First) is proposed for HS-DSCH (High Speed Downlink shared channel) in HSDPA (High Speed Downlink Packet...
I would like to express my gratitude to Dr.Dheeraj Sanghi for his invaluable guidance and inspiration throughout my thesis work. In addition to his support and exibility, I would like to thank him for his patience during periods of slow progress. I am very happy to have had the opportunity...
Packet Scheduling Algorithms to Support QOS in Networks The choice of the packet scheduling algorithm to be used at switching nodes is very crucial to provide the quality of service We have conducted a literature survey covering various scheduling disciplines that can be used to provide ...

The emergence of new multimedia applications with different QoS requirement has lead to serious challenge in maintaining video quality over error-prone tra... YS Baguda,N Fisal,SK Yusof,... - DBLP 被引量: 3发表: 2009年 Distortion Measurement based Dynamic Packet Scheduling of Video Stream over...
To support QoS, sophisticated packet scheduling algorithms, such as fair queueing, are needed to manage queueing points. However, the bulk of current research in packet scheduling algorithms assumes an output buffered switch architecture, whereas most high performance switches are input buffered. While ...
The packet scheduler is the traffic control module that regulates how much data an application (or flow) is allowed, essentially enforcing QOS parameters that are set for a particular flow. The packet scheduler incorporates three mechanisms in its scheduling of packets:...
Guaranteed Quality-of-Service (QoS) is a predominant requirement from modern high-performance switches and routers. Such devices are expected to support a large number of ports at high line rates carrying traffic with diverse statistical properties. In this paper a scheduling scheme for high-performa...
This paper proposes a cross-layer packet scheduling scheme for QoS support in audio-video transmission with IEEE 802.11e HCCA and assesses application-level QoS and QoE of the scheduling scheme under lossy channel conditions. In the proposed scheme, the access point (AP) basically allocates transmi...
Furthermore, we propose a group of algorithms to improve the existing Log-rule, Linear-rule, and Modified Largest Weighted Delay First (M-LWDF) scheduling strategies. This is achieved by including in the algorithms the QCI parameters in order to balance the QoS delivery for different traffic-...
This post highlights the Queue Scheduling Modes and Packet Loss Policies, as part of the section QoS Implementation - QoS Issues. Please see more details below. Issues 2 and 3 describe how to classify and mark packets using priority mapping or MQC. After packets are classified, packets need to...
