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]
Average-Case Analysis of Isospeed Scalability of Parallel Computations on Multiprocessors
White Paper The performance metrics are average-speed and isospeed scalability. By modeling parallel algorithms on multiprocessors using task precedence graphs, this paper is mainly interested in the effects of synchronization overhead and load imbalance on... [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]
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. This paper use a game-theoretic approach to investigate the... [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]
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]
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. Full testing of the performance of these devices requires close coordination of user plane traffic... [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]
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]
Bandwidth Estimation: Metrics, Measurement Techniques, and Tools
White Paper Existing bandwidth estimation tools measure one or more of three related metrics: capacity, available bandwidth, and Bulk Transfer Capacity (BTC). Currently available bandwidth estimation tools employ a variety of strategies to measure these metrics. [08 Jul 2008]
Evaluating Host Intrusion Detection Systems.
White Paper Quantitative metrics for HIDSs are necessary for comparing HIDSs or determining the optimal operational point of a HIDS. While HIDSs and Network Intrusion Detection Systems (NIDSs) greatly differ, similar evaluations have been performed on both... [05 Jul 2008]
A Model-Driven Business Process Integration Solution That Offers Better Tracking, Measurement and Control Capabilities
White Paper Performance monitoring was hindered by inconsistent processes and metrics; the process was undocumented and practiced differently in each region. Provider data load is the process of adding or terminating a healthcare provider in an insurer's... [01 Jul 2008]
Using Intrusion Detection Systems With a Firewall: Evaluation on DARPA 99 Dataset
White Paper Individual and combined performance is characterized using multiple performance metrics. In this paper, two open-source network intrusion detection systems - Snort and Pakemon - are combined with Cisco IOS Firewall intrusion detection features to... [30 Jun 2008]
An Overview of Issues in Testing Intrusion Detection Systems
White Paper Many past evaluation are reviewed that have been designed to assess these metrics. This paper explores the types of performance measurements that are desired and that have been used in the past. While intrusion detection systems are becoming... [30 Jun 2008]
