whitepaper Nortel Network Case Study: Erlanger Health System2007-01-01 Nortel Networks
  Located in Chattanooga, Tennessee, Erlanger is a leading provider of healthcare services to patients in 50 surrounding counties. Committed to healing, teaching, and leading Erlanger has looked to Nortel to provide converged solutions to meet their business critical IT needs. A degradation in service level or loss of service can impact the care given to many patients and could delay or hamper a critical surgery. The network architecture team at Erlanger recognized the need to implement a policy-based system for managing network Quality of Service (QoS) and access security. Enterprise Policy Manager is used to create, deploy, and maintain policies controlling network QoS at Erlanger.

whitepaper HybriCore Technology: Delivering End-to-End System-Level QoS Functionality2007-01-01 Enigma Semiconductor
  Enigma's HybriCore backplane interconnect chipset offers some compelling advantages to system OEMs in terms of density, system power and scalability. However, one of the clear questions that system architects, who are designing the next generation of multi-service access and aggregation platforms, must resolve is how this technology can be augmented with other key silicon building blocks to build compelling, complete systems. Some silicon providers have postulated that it is impossible to embed end-to-end quality of service functionality without the use of switch devices which embed the traffic management functionality.

whitepaper Control Mechanism for QoS Guaranteed Multicast Service in OVPN Over IP/GMPLS Over DWDM2007-01-01 Academy Publisher
  OVPN over IP/GMPLS over DWDM technology with QoS assurances is considered as a promising approach for the next generation OVPN. This paper suggests a multicast OLSP (Optical Label Switched Path) establishment mechanism for supporting high bandwidth multicast services in OVPN over IP/GMPLS over DWDM. For the establishment of the multicast OLSP, the paper proposes a new multicast tree generation algorithm VS-MIMR that finds the minimum interference path between virtual source nodes. The paper also suggests an entire OVPN control mechanism to adapt the operation of the routing and signaling protocols of GMPLS.

whitepaper Evaluation of Three CAC Methods: Gaussian Approximation Method, Method of Effective Bandwidth and Diffusion Approximation Method2006-12-18 Slovak University of Technology in Bratislava
  The greatly variable requirements of different applications, particularly those of video and data sources, make high demands on the development of traffic control in ATM networks. Connection admission control is a traffic control function which requires knowledge of traffic behavior, switching architecture, etc. and its impact on Quality of Service (QoS). Development of CAC schemes depends on many factors and it is not possible to have one single universal method suitable for all instances. CAC method must be first verified, if it is suitable as traffic control in ATM node with specific input traffic behavior. In this paper the intensive and weak properties of three CAC methods are presented: Gaussian, effective bandwidth and diffusion approximation method.

whitepaper Providing QoS in OSPF Based Best Effort Network Using Load Sensitive Routing2006-12-16 Reed Elsevier
  There has been an upsurge in real time applications like Voice over IP, video streaming on the Internet. These applications require Quality of Service (QoS) to perform satisfactorily. But the current Internet is built on best effort infrastructure. Hence there is need for providing QoS on top of best effort network. Usually it is relatively easy to provide QoS to real time application when the application starts. But it is quite difficult to repair the QoS when QoS deteriorates in the middle of running of the application. For example, there are few mechanisms available to provide QoS to VOIP calls when a request for call arrives.

whitepaper A New Approach to Dynamic Bandwidth Allocation in Quality of Service Networks: Performance and Bounds2006-12-06 Reed Elsevier
  Efficient dynamic resource provisioning algorithms are necessary to the development and automation of Quality of Service (QoS) networks. The main goal of these algorithms is to offer services that satisfy the QoS requirements of individual users while guaranteeing at the same time an efficient utilization of network resources. This paper introduces a new service model that provides per-flow bandwidth guarantees, where users subscribe for a guaranteed rate; moreover, the network periodically individuates unused bandwidth and proposes short-term contracts where extra-bandwidth is allocated and guaranteed exclusively to users who can exploit it to transmit at a rate higher than their subscribed rate. To implement this service model the paper proposes a dynamic provisioning architecture for intra-domain Quality of Service networks.
