whitepaper Harryda Municipality Improves Service to Residents With Service-Oriented IT Architecture2008-02-01 Oracle
  The municipality of Harryda, which is part of the Goteborg region, is located between Goteborg and Boras, Sweden. It has approximately 32,000 residents, and more than half of the largely rural municipality is covered by forest. It needed to improve operational efficiency by automating processes, to provide more responsive service to citizens and accelerate and streamline municipal affairs by integrating many of the municipality's IT systems. Harryda implemented Oracle SOA Suite as a stabile and scalable platform for integrating existing systems with each other and with new systems.

whitepaper Virtuozzo Containers for Windows Capacity and Scaling2008-02-11 Parallels
  One of the keys to a successful virtualization project is the effective management of virtualized servers. Without proper optimization, your virtual infrastructure may experience performance and even stability issues.

This white paper provides IT managers with the tools to plan and implement a Parallels Virtuozzo virtualization project, including how to evaluate and optimize the performance of virtualized severs. Read detailed information about consolidation ratios, resource usage and evaluation, and system density to ensure you achieve the full benefits of a virtualized infrastructure.

whitepaper "Faster Packet Forwarding in a Scalable Ethernet Architecture"2008-01-07 Princeton University
  Enterprise networks are medium-to-large networks which connect a few hundred or a few thousand end hosts to each other and to other networks, such as the Internet. Providing reliable and efficient networking service while minimizing the need for network administration is a critical need in today's world where availability is a priority but the time and artifice of human network administrators is often at a premium. Some protocol must be used to serve as the foundation for these networks. However, the most obvious choices for this task (Internet Protocol and Ethernet) are both inappropriate; Ethernet cannot scale to large networks, and IP scales well but is overly difficult to configure effectively.

whitepaper Streams, Security and Scalability2008-01-01 AT&T Labs-Research
  Network-based attacks, such as DDoS attacks and worms, are threatening the continued utility of the Internet. As the variety and the sophistication of attacks grow, early detection of potential attacks will become crucial in mitigating their impact. This paper argues that the Gigascope data stream management system has both the functionality and the performance to serve as the foundation for the next generation of network intrusion detection systems.

whitepaper Design and Scalability of NLS, a Scalable Naming and Location Service2008-01-01 Rice University
  This paper sketches the design, and presents a scalability analysis and evaluation of NLS, a scalable naming and location service. NLS resolves textual names to the nearest of a set of replicated objects associated with that name, and is designed to scale to the dimensions of a world-wide service. Applications include resolving Web URIs to the nearest cached or replicated object that provides the associated content. The key design goals of NLS are scalability, performance, availability and ease of administration. NLS is based on a dynamically configured, distributed search tree, with a fat-tree based topology at the global level and spanning trees at the local level. Analysis and preliminary empirical results obtained with a prototype implementation indicate that the system scales as expected.

whitepaper Scalability and Accuracy in a Large-Scale Network Emulator2008-01-01 Duke University
  This paper presents ModelNet, a scalable Internet emulation environment that enables researchers to deploy unmodified software prototypes in a configurable Internet-like environment and subject them to faults and varying network conditions. Edge nodes running user-specified OS and application software are configured to route their packets through a set of ModelNet core nodes, which cooperate to subject the traffic to the bandwidth, congestion constraints, latency, and loss profile of a target network topology. This paper describes and evaluates the ModelNet architecture and its implementation, including novel techniques to balance emulation accuracy against scalability.   
whitepaper A Scalability Service for Dynamic Web Applications2008-01-01 Carnegie Mellon University
  Providers of dynamic Web applications are currently unable to accommodate heavy usage without significant investment in infrastructure and in-house management capability. This goal is to develop technology to enable a third party to offer scalability as a subscription service with "Per-click" pricing to application providers. This paper has developed a prototype proxy caching system able to scale delivery of dynamic Web content to a large number of users. This paper reports initial positive results obtained from this prototype that point to the feasibility of this goal. It also reports the shortcomings of the current prototype, the chief one being the lack of a scalable method of managing data consistency.   
whitepaper Modularizing Variability and Scalability Concerns in Distributed Real-Time and Embedded Systems With Modeling Tools and Component Middleware2008-01-01 Vanderbilt University
  Developing real-time software for large-scale Distributed Real-time and Embedded (DRE) systems is hard due to variabilities that arise from integration with various subsystems based on different programming languages and hardware, OS, middleware platforms, fine tuning the system to satisfy a range of customer requirements, such as various Quality-of-Service (QoS) properties, and changing functional and QoS properties of the system based on available system resources. This paper describes the experience of applying Model-Driven Development (MDD) tools and QoS-enabled component middleware technologies to address domain- and middleware-specific variability challenges in an inventory tracking system, which manages the storage and flow of items in warehouses.

whitepaper Correctness Properties for Internet Routing2008-01-01 Massachusetts Institute of Technology
  This paper motivates and presents a correctness specification for Internet routing. This specification is based on three properties - route validity, path visibility, and safety. This specification may be of use to people developing tools to check routing configurations, to people designing solutions to specific problems in the current system, and to designers of new protocols and routing architectures, all of whom can benefit from knowing what it means for Internet routing to be "Correct".

whitepaper Analyzing the Scalability of Graph Algorithms on Eldorado2008-01-01 Institute of Electrical and Electronics Engineers
  The Cray MTA-2 system provides exceptional performance on a variety of sparse graph algorithms. Unfortunately, it was an extremely expensive platform. Cray is preparing an Eldorado platform that leverages the Cray XT3 network and system infrastructure while integrating a new revision of the MTA-2 processors that is pin compatible with the AMD Opteron socket. Unlike the MTA-2, this platform will have a more constrained network bisection bandwidth and will pay a high penalty for random memory accesses. This work assesses the hardware level scalability of the Eldorado platform on several graph algorithms.
