RSS metricsA Distributed System Reference Architecture for Adaptive QoS and Resource Management
White Paper Thus, a scheme is presented for dynamically managing distributed computing resources by continuously computing and assessing QoS and resource utilization metrics that are determined a posteriori. This paper deals with large, distributed real-time... [18 Jul 2008]
A Quality-of-Service Architecture for High-Performance Numerical Components
White Paper The paper describes quality metrics that are important for high-performance numerical simulations, including computational cost, accuracy, and rates of convergence and failure. The paper discusses the use of the architecture and quality metrics in... [17 Jul 2008]
Sales and Operations Planning: The Key to Continuous Demand Satisfaction
White Paper Through interdepartmental collaboration, they create business plans with the latest and most accurate data and use a common set of metrics. Find out how leading companies are designing their sales and operations planning processes to continuously... [17 Jul 2008]
Average-Case Analysis of Isospeed Scalability of Parallel Computations on Multiprocessors
White Paper The performance metrics are average-speed and isospeed scalability. This paper investigates the average-case speed and scalability of parallel algorithms executing on multiprocessors. By modeling parallel algorithms on multiprocessors using task... [11 Jul 2008]
Optimized Routing Adaptation in IP Networks Utilizing OSPF and MPLS
White Paper It presents a novel algorithm based on simulated annealing to optimize link metrics in OSPF networks. In this paper routing adaptation methodologies are investigated, which utilize conventional routing protocols such as OSPF in combination with MPLS. [11 Jul 2008]
On Selfish Routing in Internet-Like Environments
White Paper Such approaches result in selfish routing, because routing decisions are no longer based on system-wide criteria but are instead designed to optimize host-based or overlay-based metrics. A recent trend in routing research is to avoid inefficiencies... [11 Jul 2008]
Performance Modeling of Epidemic Routing
White Paper While an analytical study of Markovian models is quite complex and numerical solution impractical for large networks, the corresponding ODE models yield closed-form expressions for several performance metrics of interest, and a numerical solution... [11 Jul 2008]
Path Selection and Bandwidth Allocation in MPLS Networks
White Paper The optimization is based upon the minimization of a non-linear objective function which under light load simplifies to OSPF routing with link metrics equal to the link propagation delays. Multi-protocol Label Switching extends the IP destination... [11 Jul 2008]
Server Load Balancing Using Adaptive Routing on an MPLS Enabled Network
White Paper The paper proposes that service requests destined for a web cluster be distributed across the mirrored servers by changing dynamically the route cost metrics. As companies demand greater scalability, performance, and availability from their network... [11 Jul 2008]
Latency- and Bandwidth-Minimizing Optimal Failure Detectors
White Paper The paper provides two variants of the optimal solution for optimality metrics appropriate for two different deployment scenarios. Failure detectors are fundamental building blocks in distributed systems. [11 Jul 2008]
Performance and Scalability of Self-Organizing Hierarchical Ad Hoc Wireless Networks
White Paper Modifications to ad hoc routing metrics for energy efficiency are also considered. A novel self-organizing hierarchical architecture is proposed for improving the performance and scalability properties of ad hoc wireless networks. [11 Jul 2008]
Real-Time I/O Performance Metrics and Tests for Industrial Ethernet
White Paper Performance metrics and tests for IT infrastructure equipment have been used for many years, but now with real-time communications being used more, users are asking whether their desktop, laptop, or palm computer can handle the performance... [10 Jul 2008]
Multi-Protocol Label Switching (MPLS) and Core Router Testing
White Paper While traditional metrics are useful in quantifying performance in the data plane, they do not provide meaningful measurements in the control plane. The new breed of routers on the market has been designed to meet more demanding requirements in the... [10 Jul 2008]
Evaluating the Performance of Middleware Load Balancing Strategies
White Paper Key features of Cygnus are its ability to make load balancing decisions based on application-defined load metrics, dynamically (re)configure load balancing strategies at run-time, and transparently add load balancing support to client and server... [10 Jul 2008]
On the Scalability-Performance Tradeoffs in MPLS and IP Routing
White Paper MPLS has been regarded as an enhancement to traditional IP routing, which has the following problems: all packets with the same IP destination address have to follow the same path through the network; and paths have often been computed based on... [10 Jul 2008]
