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. For Voice-Over IP, this means prioritizing voice packets over the network to avoid... [18 Jul 2008]
A Mobile Differentiated Services QoS Model
White Paper Such IP-based networks must include Quality of Service (QoS) mechanisms to enable the usage of real-time applications, such as mobile telephony. UMTS networks will be based on the Internet Protocol (IP) to provide an efficient support for... [18 Jul 2008]
Juniper EX-Series Ethernet Switches: QoS-Enabling the Enterprise - Assuring End-to-End Application Performance
White Paper The right set of Quality of Service (QoS) tools is critical to meeting this challenge. IT's challenge is to ensure predictable performance for all applications and traffic types sharing the IP infrastructure. [18 Jul 2008]
Variety of QoS - The MNM Service Model Applied to Web Hosting Services
White Paper In order to have a competitive advantage, service providers offer different kinds of guarantees for their services which are often called Quality of Service (QoS) parameters. In today's IT environments customers often have to rely on best-effort... [18 Jul 2008]
VoIP Network Dimensioning Using Delay and Loss Bounds for Voice and Data Applications
White Paper Simulation and analytical methods are used to enhance the provisioning process, which ultimately aims to provide the delivery of consistent Quality of Service (QoS). This paper analyses resource provisioning for enterprise Voice-over-IP (VoIP... [18 Jul 2008]
Case Study in Assessing Subjective QoS of a Mobile Multimedia Web Service in a Real Multi-Access Network
White Paper This paper presents an empirical task-based user evaluation, which was carried out for the purpose of assessing the subjective QoS of a mobile multimedia web service in a real multi-access network environment comprising of WLAN and GPRS networks... [18 Jul 2008]
VFMAs, Virtual-Flow Multipath Algorithms for MPLS
White Paper A centralized and a distributed routing algorithms are proposed, which aggregate IP flows entering the MPLS domain, and optimally partition them among virtual flows that are forwarded on multiple paths according to their Quality of Service (QoS... [18 Jul 2008]
QoS Perspective for Wireless Scenarios
White Paper This paper analyze QoS parameters from the network perspective looking on three different TCP/IP layers: Transport Layer (TCP and UDP), Network Layer (DSDV, DSR and AODV), and Medium Access Control Layer (DCF and EDCF). [18 Jul 2008]
Allied Telesyn Revolutionizes the Telco Industry Solution Lays the Foundation for Video Services Over ADSL
White Paper After considering MWT's needs and network requirements, Allied Telesyn presented a full system solution for deploying IP Video over ADSL using its Ethernet-based products. In order to truly compete with cable providers, the video service needed to... [18 Jul 2008]
