whitepaper Enhanced Cost Optimized VPN Provisioning Algorithm2008-02-01 Kalasalingam University
  A Virtual Private Network (VPN) aims to emulate the services provided by a private network over the shared Internet. The endpoints of VPN are connected using abstractions such as Virtual Channels (VCs). Reliability of an end-to-end VPN connection depends on the reliability of the links and nodes. VPN service providers provide new services with Quality of Service (QoS), guarantees are also resilient to failures. Supporting QoS connections requires the existence of routing mechanisms that computes the QoS paths, where these paths satisfy the QoS constraints.

whitepaper Using Attribute-Managed Storage to Achieve QoS2008-01-31 Hewlett-Packard (HP)
  Specification of storage systems by means of user-oriented Quality-of-Service attributes is the key to ease of use and efficient resource utilization. Attribute-managed storage systems hide details of the underlying storage systems through virtual store abstractions - units of storage with quality of service guarantees. The mapping of virtual stores onto physical storage devices can be optimized to achieve high level goals such as balancing system performance against total system cost. The paper demonstrates the feasibility of this approach with a prototype matching engine called Forum.

whitepaper An Adaptive Bandwidth Request Mechanism for QoS Enhancement in WiMax Real Time Communication2008-01-31 Larsen & Toubro Infotech
  The IEEE 802.16 standard for broadband wireless metropolitan area network supports real time and non-real time services. It has a provision to design new packet-scheduling algorithms according to requirements to support Quality of Service (QoS) for real-time services. Till now published literature on WiMax states that, a Service Station (SS) requests for bandwidth to a Base Station (BS) for already arrived packets at SS from users. The BS then allocates the bandwidth to SS according to priority-based request. This paper proposes a novel adaptive-bandwidth scheduling algorithm at SS, for real-time Polling Services (rtPS), wherein the SS predicts the arrival of rtPS packets prior to the arrival and requests the BS for bandwidth in advance.

whitepaper Providing End-to-End Network QoS Via Overlay Networks and Bandwidth On-Demand2008-01-15 Sun Microsystems
  This paper examines why and how Overlay Networks are used to address the need for End-to-End assured Quality of Service (QoS) for Internet-based transport services. For organizations that provide services and products over the Internet, assured network QoS is highly important because it is a key factor in determining the quality of end-user experience their customers have. The main contributions of this paper are the identification and analysis of basic architecture design patterns required to build overlay network-based value-added functions such as QoS assurance, and the proposal and analysis of reconfigurable networking (bandwidth on-demand) as a an approach for expanding the range services and capabilities available on existing networks.

whitepaper IPL Case Study - ntl: (Virgin Media)2008-01-14 IPL
  ntl:, now part of Virgin Media, was the UK's leading supplier of bundled services to residential customers. These included a range of digital and analogue cable television, broadband internet and telephone services. The company's top priority was quality of service i.e. ensuring the consistent delivery of the required services to each of its customers, with rapid identification and correction of any faults. However its existing TV surveillance facilities were failing to provide effective monitoring or fault identification facilities. ntl: selected IPL to develop a prototype Remote Quality of Service (RQoS) system. IPL constructed and developed a successful prototype, then developed the full-scale system, and helped to roll it out to the 23 regions of ntl:'s largest network.   
whitepaper BodyQoS: Adaptive and Radio-Agnostic QoS for Body Sensor Networks2008-01-03 College of William and Mary
  As wireless devices and sensors are increasingly deployed on people, researchers have begun to focus on wireless body-area networks. Applications of wireless body sensor networks include healthcare, entertainment, and personal assistance, in which sensors collect physiological and activity data from people and their environments. In these body sensor networks, quality of service is needed to provide reliable data communication over prioritized data streams. This paper proposes BodyQoS, the first running QoS system demonstrated on an emulated body sensor network. BodyQoS adopts an asymmetric architecture, in which most processing is done on a resource rich aggregator, minimizing the load on resource limited sensor nodes.

whitepaper Dynamic Issues in MPLS Service Restoration2008-01-01 University of New Hampshire
  Packet loss and reordering are the most significant negative effects resulting from protection switching. In conventional MPLS networks, the detection and retransmission of out-of-order or lost packets is left to the higher layers, which in effect, degrades the overall performance. This paper proposes a signaling mechanism to minimize the impact of protection switching on packet loss and reordering. The proposed signaling protocol is general and independent of the particular MPLS protection mechanism.

whitepaper Neural-Based Quality of Service Estimation in MPLS Routers2008-01-01 Higher Institute of Computer Modelling and their Applications
  The MultiProtocol Label Switching (MPLS) is being considered as one possible approach for scalable Quality of Service (QoS) provisioning in the Internet. As MPLS is standardized by Internet Engineering Task Force (IETF) and is expected to be implemented in the near future, this paper addresses the issue of QoS estimation in a MLPS router fed with bursty traffic by means of a neural network. The latter is trained to anticipate the average delay and the Packet Loss Rate (PLR) within the MPLS node for each class of service, given the mean rates, the peak rates and the coefficients of variation of the packet inter-arrival time of the incoming traffic flows.

whitepaper The Bandwidth Exchange Architecture2008-01-01 Drexel University
  New applications for the Internet such as video on demand, grid computing etc. depend on the availability of high bandwidth connections with acceptable Quality of Service (QoS). There appears to be, therefore, a requirement for a market where bandwidth-related transactions can take place. For this market to be effective, it must be efficient for both the provider (seller) and the user (buyer) of the bandwidth. This implies that: (a) the buyer must have a wide choice of providers that operate in a competitive environment, (b) the seller must be assured that a QoS transaction will be paid by the customer, and (c) the QoS transaction establishment must have low overheads so that it may be used by individual customers without a significant burden to the provider.

whitepaper A Reservation Scheme Satisfying Bandwidth QoS Constraints for Ad-Hoc Networks2008-01-01 University of Antwerp
  Achieving QoS (Quality of Service) in Mobile Ad-hoc NETworks (MANET) has been a research topic in the last years. This paper describes a QoS reservation mechanism for Routing Ad-hoc Networks. The mechanism is targeted for sources requiring a bandwidth allocation. The mechanism is based on the knowledge of the bandwidth requirements of the neighbors of a node and the interferent nodes in the cover area of each node. The paper describes as the protocol could be integrated in AODV and OLSR.
