whitepaper Control System for Internet Bandwidth Based on Java Technology2008-07-07 Journal of Theoretical and Applied Information Technology
  This paper presents a Java-based real-time Internet access estimation tool for Quality of Service (QoS) in Internet accesses for Multimedia applications (JEQoSIM). It is specially aimed for real-time multimedia applications which use the User Datagram Protocol (UDP). The system is capable of estimating access capacity, available bandwidth and delay as the critical end-to-end QoS parameters for this kind of applications. The algorithm used for QoS estimations is one-way, and is based on the packet train technique. Real-time QoS estimation elements are distributed among a central server and the Internet end user. The central server contains a UDP packet bursts server and a web server that hosts the Java applet that implements the UDP packet bursts client.

whitepaper A Two-Tiered On-Line Server-Side Bandwidth Reservation Framework for the Real-Time Delivery of Multiple Video Streams2008-07-01 Boston University
  The advent of virtualization and cloud computing technologies necessitates the development of effective mechanisms for the estimation and reservation of resources needed by content providers to deliver large numbers of Video-On-Demand (VOD) streams through the cloud. Unfortunately, capacity planning for the QoS-constrained delivery of a large number of VOD streams is inherently difficult as VBR encoding schemes exhibit significant bandwidth variability. This paper presents a novel resource management scheme to make such allocation decisions using a mixture of per-stream reservations and an aggregate reservation, shared across all streams to accommodate peak demands.

whitepaper Deploying RSVP in Multiple Security Domains Networks: Securing Application Quality of Service2008-07-01 Cisco Systems
  This white paper brings out a possible solution for deploying Resource Reservation Protocol (RSVP) admission control within a multiple security domains network. Multiple security domains networks, as they are deployed today, often lack strict QoS guarantees, deterministic performance, application-aware and user-aware policy enforcement, and efficient bandwidth utilization. RSVP-based admission control solution is a widely accepted mechanism to provide all these benefits in an enterprise environment. However, deploying RSVP inside a multiple security domains network requires special attention to achieve end-to-end resource reservation across the security boundaries.   
whitepaper Maintenance Company Consolidates with Terminal Services2008-06-04 Microsoft
  Tube Lines provides maintenance and support services for the London Underground. With employees spread across more than 90 locations, Tube Lines relied on its terminal services solution to deliver central access to applications. However, limited scalability and low bandwidth affected application performance and employee productivity. The company added more server computers to accommodate its users, but this increased the management burden and strained network resources further. To improve performance and simplify management, Tube Lines is implementing Windows Server® 2008 Terminal Services on 64-bit servers from HP. The company expects to decrease terminal services hardware by 80 percent, making management easier. The company will reduce costs as a result. In addition, faster connections and improved stability will help employees to work more easily

whitepaper An Architectural Model to Provide QoS in a Home Network and Its Evaluation in a Real Testbed2008-06-01 Academy Publisher
  Home networks are an evolution of office local area networks, answering the need for residential distribution of broadband services. The design of a home network must strive to keep low costs, easy installation and maintenance while at the same time providing a large variety of services, from voice and data applications to multimedia streaming. A successful platform for home networking must put together simple interfaces for the users and sophisticated mechanisms for managing the distribution of the desired broadband services. This paper proposes mechanisms to support flows with different Quality of Service (QoS) requirements in a home network whose architectural model has been defined in the framework of the European IST ePerSpace project.

whitepaper Sustaining Negotiated QoS in Connection Admission Control for ATM Networks Using Fuzzy Logic Techniques2008-05-20 University of Ibadan
  The objective of Connection Admission Control (CAC) is to keep the network load moderate to achieve a performance objective associated with Quality of Service (QoS). Cell Loss Ratio (CLR), a key QoS parameter in ATM networks, is essential for proper network resources dimensioning, congestion control, bandwidth allocation and routing. This paper employed fuzzy logic technique in Statistical Connection Admission Control (S-CAC) - a CAC employing multiplexing of the bandwidth between the peak cell rate and the sustained (average) cell rate. The fuzzy technique consists of an input stage, a processing stage, and an output stage. The paper defined the rules with "Max-min" inference method in which the output membership function is given the truth value generated by the premise.

whitepaper Multiobjective Optimization of SLA-Aware Service Composition2008-04-25 University of Massachusetts
  In Service Oriented Architecture, each application is often designed as a set of abstract services, which defines its functions. A concrete service(s) is selected at runtime for each abstract service to fulfill its function. Since different concrete services may operate at different Quality of Service (QoS) measures, application developers are required to select an appropriate set of concrete services that satisfies a given Service Level Agreement (SLA) when a number of concrete services are available for each abstract service. This problem, the QoS-aware service composition problem, is known NP-hard, which takes a significant amount of time and costs to find optimal solutions (optimal combinations of concrete services) from a huge number of possible solutions.

whitepaper Adaptive Bandwidth Management and Reservation Scheme in Heterogeneous Wireless Networks2008-04-15 Institute of Electrical and Electronics Engineers
  In order to support multiple types of service with different QoS requirements in heterogeneous wireless networks, efficient resource management, call admission control strategies, and mobility management are important issues. This paper proposes Bandwidth Management Strategy 1 (BMS1), Bandwidth Management Strategy 2 (BMS2) and reservation scheme with Fuzzy controller for real-time services. Simulation result shows that the proposed methods balance resource utilization outperforms the previous work and traditional CAC by improving the Call Reject Probability (CRP).

whitepaper Impact of QoS on Application Response Time2008-04-01 Research India Publications
  Quality of Service (QoS) recourses to the capability of a network to provide better service to selected network traffic over various technologies. This paper compares three different algorithms for packet queuing using the simulator program OpNet (OpNet is a network simulator, including a library of detailed protocol and application models (e.g. Voice, HTTP, TCP, IP), the Standard Model Library includes hundreds of vendor specific and generic device models including routers, switches, workstations, and packet generators). This paper supposes a corporation has developed a custom database application. This application stores corporate product information.   
whitepaper A QoS Provisioning Framework for Wireless Mesh Network2008-03-06 Thales
  Moving on from the first generation of Wireless Mesh Networks (WMNs), where community and city-wide type mesh networks are deployed to provide best-effort network access, the next generation WMNs is about extending its capability to allow Quality of Service (QoS) at carrier grade level, enabling real-time and multimedia applications to be offered to users of the network. Whilst technologies exist to support QoS, they provide no real answer to offering QoS network-wide across WMN. In this paper, a QoS provisioning framework is therefore proposed that provides a combination of resource provisioning and routing for WMN.
