whitepaper HAWAII: A Domain-Based Approach for Supporting Mobility in Wide-Area Wireless Networks0000-00-00 Alcatel-Lucent
  Mobile-IP is the current standard for supporting macro-mobility of mobile hosts. However, in the case of micro-mobility support, there are several competing proposals. This paper presents the design, implementation, and performance evaluation of HAWAII: a domain-based approach for supporting mobility. HAWAII uses specialized path setup schemes which install host-based forwarding entries in specific routers to support intra-domain micro-mobility. These path setup schemes deliver excellent performance by reducing mobility related disruption to user applications. Also, mobile hosts retain their network address while moving within the domain, simplifying QoS support. Furthermore, reliability is achieved through maintaining soft-state forwarding entries for the mobile hosts and leveraging fault detection mechanisms built in existing intra-domain routing protocols.

whitepaper QOS, QOE and Total Customer Experience0000-00-00 Masergy
  Business success requires productively and simply leveraging an increasingly rich menu of IP network-based Multimedia, Internet, Communications and Entertainment (MICE) capabilities. Due to the sophistication required to provide, support and manage MICE capabilities they are often purchased as services from a service provider. Because MICE services are critical to business success, organizations of all sizes are evolving to an enlightened, business-focused method of choosing network services and service providers called Total Customer Experience (TCE). This white paper, by James P. Cavanagh of The Consultant Registry, describes the evolution toward a TCE approach and the benefits and clarity that TCE brings to the marketplace.

whitepaper Adaptive Quality of Service for a Mobile Ad Hoc Network0000-00-00 University of California
  This paper presents a QoS routing system for MANET supporting multiple traffic classes. The system takes into consideration clustering and channel allocation. Simulation experiments show that the algorithms are convergent. The system also yields a higher total throughput compared to the case in which every interface uses the same channel.

whitepaper Allocating Resources to Multiple Antenna Mobile Nodes in Fading Wireless Ad-Hoc Networks With Temporally Correlated Loss0000-00-00 University of California
  Addressing the tradeoff between the Quality of Service (QoS) and consumed power is a critical issue for wireless ad-hoc networks. The loss observed in such networks is often temporally correlated. Multiple antenna systems utilizing space-time block codes are gaining increasing popularity as the result of being adopted by different wireless standards. This paper focuses on optimal resource allocation schemes for wireless ad-hoc networks with mobile nodes utilizing space-time block codes. Relying on adaptive modulation techniques for multiple antenna systems, this paper examines optimal schemes of maximizing throughput under power and loss constraints as well as minimizing transmission power under throughput and loss constraints.

whitepaper A Shoelace-Based QoS Routing Protocol for Mobile Ad Hoc Networks Using Directional Antenna2007-08-01 National Chung Cheng University
  This paper proposes a new QoS routing protocol for Mobile Ad hoc NETwork (MANET) using directional antenna. The scheme offers a bandwidth-based routing protocol for QoS support in MANET using the concept of multi-path. The MAC sub-layer adopts the CDMA-over-TDMA channel model. The QoS on-demand routing protocol determines the end-to-end bandwidth calculation and bandwidth allocation from a source node to a destination node. The paths are combined with multiple cross links, called as shoelace, when the network bandwidth is strictly limited. Due to the directional antenna property, these cross links can simultaneously transmit data without any data interference.

whitepaper A Data Specification Model for Multimedia QoS Negotiation2007-08-01 ericsson
  An important issue for multimedia Quality of Service (QoS) negotiation is the specification of the parameters/profiles that need to be coordinated in order to reach an agreement among involved entities regarding service configuration, resource allocation, and the dynamics of service adaptation. The contribution of this paper is a generic Data Specification Model, including specification of both input and output data for the QoS negotiation process. The applicability of the proposed model is illustrated for an example multimedia service scenario.

whitepaper MPLS QoS and Streamsense2007-08-01 Streamcore
  Despite the increase of available bandwidth, problems persist concerning congestion on WAN access links. To address these issues, the paper explains MPLS VPN-IP proposed by service providers has been combined with the implementation of Class of Service within CE and PE routers. Unfortunately, this is a fairly rudimentary solution that only partially solves application performance problems. Specifically, processing within a given Class of Service remains on a Best-Effort basis, and sessions classified within a single Class of Service may interfere with one another during congested periods.

whitepaper Amman Stock Exchange Invests in a New and Innovative Network2007-08-01 Extreme Networks
  Amman Stock Exchange (ASE) wanted a network that was capable of handling a high traffic rate at wire-speed, with minimal network downtime and high availability. The network needed to handle future growth in an easy and non-disruptive manner; as well as meet the demands for disaster recovery. ASE also needed the network solution to come with a wealth of features and options to satisfy the stringent security and Quality of Service (QoS) requirements. In search of a company to implement a solution, ASE found that the BlackDiamond switch provided by Extreme Networks, had performance figures which were superior to any other switch they evaluated.

whitepaper VoFi: Taking VOIP Wireless0000-00-00 ZDNet
  Voice over Wireless -- the merging of VoIP and Wi-Fi -- is expected to be the "next big thing" in wireless communications. A recent study showed that more than 75% of network operators and service providers surveyed have identified mobile VoIP or VoFi as a top priority for new metro Wi-Fi networks. VoFi promises higher voice quality and more reliable coverage indoors than traditional cellular service and is quickly gaining stature as a competitor to mobile broadband data. In this audiocast ZDNet executive editor David Berlind check in with Craig Mathias principal at Farpoint Group on where this technology stands and where it's headed.
