Adaptable Communication Software for Differentiated QoS

by Bharat Bhargava
"... Introduction and Research Directions The performance of network and communication software is a major concern for success of the emerging application such as E-commerce. One drawback of current Internet is the lack of QoS support which is essential for business and electronic commerce applications. ..."

. The efforts based on Integrated Services (IntServ) and RSVP are not deployable in large scale Internet Networks. They are also not appropriate for short flows such as retrievals and updates in ecommerce transactions and short-lived TCP connections. Differentiated Services (DiffServ) is a new approach for QoS

Abstract Enhancing aggregate QoS for video streaming

by Chung-wei Lee A, Y Chow B, Jonathan C. L. Liu B , 2004
"... The IETF’s Differentiated Services architecture is designed to provide different types or levels of service for Internet traffic. One of its key features is that traffic flows are aggregated so that routers in the core network only need to distinguish a relatively small number of aggregate flows, ev ..."

, even if those flows consist of hundreds or thousands of individual flows. However, network-level QoS differentiation may not satisfy the requirements of many QoS-sensitive applications such as live video streaming, where end-to-end delay and reliability must be guaranteed. This paper investigates

A QoS Architecture Integrating Mobile Ad-Hoc and Infrastructure Networks

by Sérgio Crisóstomo, Susana Sargento, Marek Natkaniec, Norbert Vicari
"... Abstract—This paper proposes an Ad-hoc QoS architecture, using as basis some concepts from SWAN, extending it to fulfill our requirements. It also proposes the modules required in the network elements and its interaction to provide optimized QoS in the ad-hoc network and integration between both net ..."

networks. We also present the overall integration QoS signaling protocol and the differentiation mechanisms to address end-to-end QoS for real-time multimedia applications. Furthermore, the proposed solution addresses the use of multipath routing in order to provide load balancing and increased network

Dynamic QoS Mapping Control for Streaming Video in Relative Service Differentiation Networks

by Jitae Shin, Jin-Gyeong Kim, Jongwon Kim, C.-C., Jay Kuo , 2001
"... A dynamic quality of service (QoS) mapping control scheme, which includes feedforward and feedback QoS control, is proposed for the differentiated services (DiffServ) networks in this work. To achieve reliable and consistent end-to-end video streaming with relative service differentiation, the propo ..."

Aggregated QoS Mapping Framework for Relative Service Differentiation-Aware Video Streaming

by Jitae Shin, Jin-Gyeong Kim, JongWon Kim, D. C. Lee, C.-C. Jay Kuo - PACKET VIDEO WORKSHOP, 30 APRIL - 1 MAY 2001, KYONGJU, KOREA , 2001
"... This research investigates the Quality of Service (QoS) interaction at the edge of differentiated service (DiffServ) domain, denoted by video gateway (VG). VG is responsible for coordinating the QoS mapping between video applications and DiffServ enabled network. To accomplish the goal of achieving ..."

Especially, we focus on building a framework for dynamic QoS mapping, which intends to overcome both the QoS demand

Dropping Based Contention Resolution for Service Differentiation to Provide QoS in Wdm OBS

by Prof. J R Pathan , Prof A R Teke , Prof. M A Parjane , Prof. P S Togrikar - 228, ISSN Print: 0976 – 6367, ISSN Online: 0976 – , 2013
"... ABSTRACT In the recent years, the bandwidth demand on the Internet is increasing phenomenally, due to rising of multimedia applications and real time applications. WDM technology enables to respond to the explosive growth of Internet traffic by exploiting huge bandwidth of the fiber. Optical burst ..."
Abstract - Cited by 1 (0 self) - Add to MetaCart
switching (OBS) in WDM is a promising technology to use in the next generation optical network. One of the challenges in OBS based network is wavelength contention to provide quality of service (QoS). QoS helps to provide priorities to different applications depending on their bandwidth requirement. In case

DS-PPS: A Practical Framework to Guarantee Differentiated QoS in Terabit Routers with

by unknown authors
"... Abstract—Parallel Packet Switch (PPS) is used intensively in today’s terabit router to construct the switching fabric. Basic PPS equally deals with all of the traffic in order to achieve uniform load-balancing and high throughput, but it fails to support differentiated QoS. With the recent blooming ..."
Abstract - Add to MetaCart
of delaysensitive Internet traffic, such as the peer-to-peer live streaming and IPTV, differentiated QoS is becoming an urgent demand. In this paper, we propose a novel and practical framework, the Differentiated Service Parallel Packet Switch (DS-PPS), which supports three fundamental QoS features: guaranteed

Pricing Network Resources for Adaptive Applications in a Differentiated Services Network

by Xin Wang, Henning Schulzrinne , 2001
"... The Differentiated Services framework (DiffServ) has been proposed to provide multiple Quality of Service (QoS) classes over IP networks. A network supporting multiple classes of service also requires a differentiated pricing structure. We propose a pricing scheme in a DiffServ environment based on ..."
