whitepaper An MPLS-DiffServ Experimental Core Network Infrastructure for E2E QoS Content Delivery2007-12-10 Demokritos
  The continuing and rapid growth of the Internet has created an extremely large capacity problem to the service and content provider's networks. The increased network traffic and the absence of service priority, usually produce high network congestions, delayed data and service transmissions and lack of throughput. The effect of these factors in A\V content transmission is to distort the initial content and decrease the content quality. To avoid this negative effect, service and content providers are looking for architectures that give them greater control on traffic passing through their domains and other heterogeneous networks. This paper proposes an experimental core network architecture (MPLS-DiffServ) presenting a solution for content providers that want reliable and agreed level of quality, even if the network is under congestion.

whitepaper Fuzzy Logic Control Based QoS Management in Wireless Sensor/Actuator Networks2007-12-06 Molecular Diversity Preservation International (MDPI)
  Wireless Sensor/Actuator Networks (WSANs) are emerging rapidly as a new generation of sensor networks. Despite intensive research in Wireless Sensor Networks (WSNs), limited work has been found in the open literature in the field of WSANs. In particular, Quality-of-Service (QoS) management in WSANs remains an important issue yet to be investigated. As an attempt in this direction, this paper develops a fuzzy logic control based QoS management (FLC-QM) scheme for WSANs with constrained resources and in dynamic and unpredictable environments. Taking advantage of the feedback control technology, this scheme deals with the impact of unpredictable changes in traffic load on the QoS of WSANs.

whitepaper Distributed Call Admission Protocol for Multi-Channel Multi-Radio Wireless Networks2007-12-06 Institute of Electrical and Electronics Engineers
  This paper proposes a Distributed Call Admission Control protocol (DCAC) to provide bandwidth and delay guaranteed Quality of Service (QoS) in multihop wireless mesh networks, by exploiting the multi-channel multi-radio (mc-mr) feature. The paper proposes a distributed link scheduling algorithm to give the bandwidth with minimal one hop delay, and a routing metric for route setup. To the best of one's knowledge, this is the first distributed protocol that embeds (mc-mr) feature into Time Division Medium Access (TDMA) to do QoS call admission in wireless mesh networks. Extensive simulations show that the protocol significantly improves network performance on supporting QoS flows compared with some widely used protocols.

whitepaper Exposing Network Services for Enhanced Competitive Edge2007-12-01 BEA Systems
  SingTel is Asia's leading communications group with operations and investments around the world. In the growing competitive telecommunications industry, SingTel needed new services revenue stream to maintain its top position. SingTel utilises BEA WebLogic Network Gatekeeper to tap on the growing consumer needs for new data services, provided by itself as well as by third party content and service providers.

whitepaper A Network and Data Link Layer Design to Improve QoS for Voice and Video in Telesurgery2007-12-01 REVISTA MEXICANA DE INGENIERIA BIOMEDICA
  The feasibility and practicability of performing telesurgery depend not only on the ability to overcome the barriers of surgery, but also on the ability to transmit data rapidly and securely. Telecommunications designers for telesurgery have focused in the transoceanic WAN links. However, if the WAN link is good enough but the Autonomous System (AS) Network to which the destination hospital belongs doesn't have the proper configuration; applications running on top could have a very poor performance. This paper presents a network and data link layer infrastructure design that classifies and prioritizes voice and video traffic in order to improve the performance and QoS of telesurgery applications.

whitepaper Wireless Network Quality of Service (QoS)2007-10-09 NetMotion Wireless
  A key challenge faced by enterprise IT management is how to ensure the productivity of the growing population of mobile workers. A successful mobile deployment can empower mobile workers with the resources they need to be effective at the point of service, resulting in a more productive workforce, expedited customer service, happier customers and increased revenue. Selecting the right mobile solutions and managing today's mobile enterprise, however, is not a simple task.

Successful mobile deployments require IT management to take a holistic approach managing all elements of the mobile deployment, including applications, wireless networks and devices. This white paper describes how Quality of Service (QoS) can enable organizations to maximize mobile worker productivity and fully leverage the benefits of their mobile deployments.

whitepaper Technical White Paper for QPPB Solution2007-11-23 Huawei Technologies
  This paper specifies how to deploy the QoS (Quality of Service) through the BGP routing policy, that is QoS Policy Propagation Through the Border Gateway Protocol (QPPB). Routes are classified through BGP-based attributes, like community list, AS paths list, ACL, and prefix list. Different QoS policies are applied to different route classifications. This paper focuses on the basic principles of the QPPB and its usage.   
whitepaper ARC: A Bottom-Up Approach to Negotiated QoS2007-11-21 Delft University of Technology
  Mobile systems operate in a resource-scarce environment and thus must adapt to external conditions; all layers must make cost-based decisions about what mode of operation to use in response to performance feedback. This paper focuses on the generic interface between adjacent layers (client and server) in a multi-level hierarchy. The Adaptive Research Contracts (ARC) framework uses a bottom-up approach in which the server exposes a range of quality/cost modes to the client above. This allows the client to trade off various algorithms generating different workloads for multiple resources. A case study shows that control can be distributed effectively over multiple layers with ARC; global cost-effective solutions can be obtained with exchanging a small fraction of all possible control settings.

whitepaper How Cisco IT Uses QoS for Critical Applications2007-11-20 Cisco Systems
  From a business value perspective, the network needed to support the user demand for greater productivity. Videoconferencing and collaboration applications running across the LAN and WAN needed to respond to the users in real or near-real time. The company had to deliver a higher level of service than they had been delivering, and they had to guarantee packet delivery. In the mid-1990s, the Cisco team had deployed basic priority queuing and Weighted Fair Queuing (WFQ), but as the network grew in size and complexity, mirroring the growth of the company, two things happened: Better QoS technologies were needed, and it became a great time to partner with the Cisco development organizations, who were developing ways to implement the best QoS capabilities across all Cisco products.

whitepaper Quartz: A QoS Architecture for Open Systems2007-11-05 Trinity College Dublin
  This paper describes an architecture that provides support for Quality of Service (QoS) specification and enforcement in heterogeneous distributed computing systems. The Quartz QoS architecture has been designed to overcome various limitations of previous QoS architectures that have constrained their use in heterogeneous systems. These limitations include dependencies on specific platforms and the fact that their functionality is often limited by design to one particular area of application. Quartz is able to accommodate differences among diverse computing platforms and areas of application by adopting a flexible and extensible platform-independent design, which allows its internal components to be rearranged dynamically in order to adapt the architecture to the surrounding environment.
