Quality of Service (QoS) in Voice-Over IP Solutions: Achieving Predictable Service
White Paper QoS, or Quality of Service, is a set of techniques to manage network resources to assure that delay-sensitive information travels the network in a timely manner. It is possible to configure the hardware and software on one's network to achieve more... [18 Jul 2008]
Wireless Network Quality of Service
White Paper QoS gives IT managers complete power over their entire mobile deployment by letting them shape and control traffic across any network that their users may connect to. QoS also lets IT management meet the ever growing population of mobile workers... [18 Jul 2008]
VoIP QoS
White Paper This white paper discusses QoS (Quality of Service) in VoIP networks. It introduces terms like Latency, Jitter, Packet Loss, PDD (Post dial Delay) etc.and explains them in QoS background. It then introduces the media transfer protocols like RTP and... [18 Jul 2008]
QNoC: QoS Architecture and Design Process for Network on Chip
White Paper This paper defines Quality of Service (QoS) and cost model for communications in Systems on Chip (SoCs), and derive related Network on Chip (NoC) architecture and design process. Communication traffic of the target SoC is analyzed (by means of... [18 Jul 2008]
An IP QoS Architecture for 4G Networks
White Paper The different phases of QoS-operation are discussed. The overall QoS concepts are presented with some relevant enhancements that address specifically voice services. This paper describes an architecture for differentiation of Quality of Service in... [18 Jul 2008]
Configuring QoS for VoIP Networks
White Paper This application note describes ways to configure Quality-of-Service (QoS) parameters on Vyatta for VoIP services in an IP Telephony network. Currently, Vyatta does not support QoS configuration in its CLI and Web GUI. [18 Jul 2008]
Deploying QoS Sensitive Services in OSGi Enabled Home Networks Based on UPnP
White Paper Enabling end-to-end Quality of Service (QoS) in the home network will push emerging services such as iDTV and pay per view to an acceptable and guaranteed user experience. Currently used QoS solutions in the wide area network can not be used in the... [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 overall algorithm was optimized to guarantee the E2E QoS parameters of each service class, especially... [18 Jul 2008]
An Evolved 3GPP QoS Concept
White Paper Simple and cost efficient means for providing and controlling Quality of Service (QoS) are important for 3GPP operators. GPP QoS concept and, based on these, explain why that demand is currently not met. [18 Jul 2008]
AMPS - ANStool: Interoperability of Automated Tools for the Provisioning of QoS Services
White Paper Modern IP-based packet networks carry a number of varying services, and one of their crucial aspects is the implementation of Quality of Service (QoS) techniques. Packet networks that support QoS can accommodate simultaneously different traffic... [18 Jul 2008]
Performance Measurements of MPLS Traffic Engineering and QoS
White Paper Providing Quality of Service (QoS) and traffic engineering capabilities in the Internet is very essential, especially to support the requirements of real-time, as well as mission critical applications. [18 Jul 2008]
Performance Analysis of QoS Supported by Enhanced Distributed Channel Access (EDCA) Mechanism in IEEE 802.11e
White Paper With fast deployment of Wireless Local Area Networks (WLANs), the ability of WLAN to support real time services with stringent Quality of Service (QoS) requirements has come into fore. This paper evaluates the capability of QoS support in Enhanced... [18 Jul 2008]
A Scalable Distributed QoS Multicast Routing Protocol
White Paper Many Internet multicast applications such as teleconferencing and remote diagnosis have Quality-of-Service (QoS) requirements. It is a challenging task to build QoS constrained multicast trees with high performance, high success ratio, low overhead... [18 Jul 2008]
Network Architecture to Support QoS in Mobile Ad Hoc Networks
White Paper This paper presents a Quality of Service (QoS) architecture for supporting real-time data transmission in Mobile Ad hoc NETworks (MANETs). Through simulations, it is found that the QoS architecture reduces packet delay and greatly improves the... [18 Jul 2008]
A New QoS Routing Framework for Solving MCP
White Paper One purpose of Quality-of-Service (QoS) routing is to develop polynomial-time heuristic algorithms to tackle the MCP (Multi-Constrained-Path) problem, which is NP-complete. This paper introduces a new QoS routing heuristic framework, which focuses... [18 Jul 2008]
