RSS diffservIPv6 Deployment: Real Time Applications and QoS Aspects
White Paper The paper describes the implementation and testing of a QoS service on IPv6 networks, which is based on the DiffServ architecture (expedited forwarding) and provides strict priorities to packets that are produced from real time applications. [04 Aug 2008]
Scalable Video Streaming Traffic Delivery in IP/UMTS Networking Environments
White Paper A prototype architecture is proposed, and is further validated, that explores the joint use of packet prioritization and Scalable Video Coding (SVC) together with the appropriate mapping of UMTS traffic classes to the DiffServ traffic classes. [04 Aug 2008]
A Scalable and Business-Oriented Framework for Inter-Domain Quality-of-Service
White Paper The paper also provides an IntServ-over-DiffServ architecture that is able to cope with mobility scenarios. This paper presents and discusses a framework for end-to-end Quality-of-Service in a network operator environment. [04 Aug 2008]
Internet QoS Signaling Protocols
White Paper Two framework QoS solutions were proposed by IETF: resource reservation (Integrated Services - IntServ) or service classification (Differentiated Services - Diffserv). The classical transfer service offered by Internet is a point-to-point best... [04 Aug 2008]
A Measurement-Based Approach for Dynamic QoS Adaptation in DiffServ Networks
White Paper This paper presents a practical approach to managing multimedia traffic in DiffServ network, using network monitoring feedback and control. The latter is determined based on reports sent by bandwidth monitors installed on each node of a DiffServ... [04 Aug 2008]
Network Services Deployment for QoS Provisioning in a Multi-Layer DiffServ Architecture
White Paper The Internet evolution delineated during the last years has necessitated the need of quality of service differentiation among IP flows that expose different characteristics regarding bandwidth, delay, packet loss, and other QoS-relative parameters. [04 Aug 2008]
An End-to-End QoS Framework With On-Demand Bandwidth Reconfiguration
White Paper ODP provides end-to-end QoS guarantees to individual flows with minimal overhead, while keeping the scalability characteristic of DiffServ. Through extensive simulations, the performance of ODP is investigated and compared with that of IntServ and... [04 Aug 2008]
Impact of Scalability in Video Transmission in Promotion-Capable Differentiated Services Networks
White Paper In this architecture, the video frames will be transported over a new generation IP network that supports Differentiated services (Diffserv). The paper also proposes a novel Two Rate Three Color Promotion-Capable Marker (trTCPCM) to be used at the... [04 Aug 2008]
QoS Techniques in Ad Hoc Networks
White Paper IntServ and DiffServ techniques can be used to manage and control IP flows through queuing, marking and dropping of packets. IP Ad-Hoc Networks are quickly becoming part of today's communications infrastructure. [04 Aug 2008]
On Scalable Attack Detection in the Network
White Paper By contrast, note that both router lookups and fair queuing have scaled to high speeds using aggregation via prefix lookups or DiffServ. Current intrusion detection and prevention systems seek to detect a wide class of network intrusions (e.g. [04 Aug 2008]
Web Server QoS Models: Applying Scheduling Rules From Production Planning
White Paper In the Differentiated Services (DiffServ) model, separate queues are introduced to differentiate QoS for separate web requests with di8erent priorities. Most web servers, in practical use, use a queuing policy based on the Best Effort model, which... [04 Aug 2008]
Seamless QoS Handling Mechanism for Macro and Micro Mobility
White Paper This architecture consists of a Differentiated Service (DiffServ) model and an Integrated Service (IntServ) model. One of the most challenging issues facing designers of wireless and mobile networks is the proper provisioning of Quality of Service... [04 Aug 2008]
DiffServ QoS Provisioning for Real Time Traffic in Frequent Handoff MobileIPv6 Networks
White Paper In this paper, DiffServ resource allocation architecture is proposed for the evolving next generation mobile IPv6 networks. The use of DiffServ eliminates the signaling overhead on mobile node during frequent handoff scenario. [18 Jul 2008]
Performance Enhancements of UMTS Networks Using End-to-End QoS Provisioning
White Paper This paper investigates end-to-end Quality of Service (QoS) provisioning approaches for UMTS networks in a DiffServ IP network environment. The effort was put on QoS class mapping from DiffServ to UMTS, Access Control, buffering and scheduling... [18 Jul 2008]
AMPS - ANStool: Interoperability of Automated Tools for the Provisioning of QoS Services
White Paper The most widely used architecture for providing QoS in today's packet networks is DiffServ, which is based on the concept of traffic classes. Modern IP-based packet networks carry a number of varying services, and one of their crucial aspects is... [18 Jul 2008]
