System Center Configuration Manager Asset Intelligence 2008-03-24 Microsoft Tips

Information technology expenditures comprise an increasing portion of IT budgets - IT assets can often account for more than half of an enterprise's total asset base. With the changing nature of today's technology and the complexity of network environments, enterprises find it difficult to track the IT assets they own. Without an accurate record of their IT assets, it is challenging for enterprises to determine if IT is providing value and to meet financial, regulatory and license compliance requirements. Microsoft System Center Configuration Manager 2007 includes hardware and software inventory and software metering capabilities that help IT organizations understand exactly what hardware and software assets they have, who is using them, and where they are.

Getting the Most Out of Your SolarWinds Orion Network: Features and Add-Ons 2007-11-30 Corona Technical Services

It's an unfortunate truth that many network administrators don't really understand how to get the most out of their network. The software may work, and the administrators may figure out a roundabout way how to do what they want, but there may be a faster, more efficient way to do what is needed. There are a number of ways to get more out of the Orion network, either by utilizing built-in features or finding separate add-ons that give the network a new dimension of usability. This paper provides a few things the reader may not know about the SolarWinds Orion network management tools.

The Changing Face of Network Management 2007-10-01 CA (Computer Associates)

Managing the network is serious business. It is absolutely essential that it is up and running since the critical business services depend on it - and so does the revenue stream. At the same time, the network continues to grow in size and complexity, with the addition of more devices and new technologies, in response to business growth and demands. Preventing network downtime and performance degradation is every IT manager's goal. Causes are not always preventable - major power outages and other external events occur - but a considerable amount of disruption can be prevented. Industry analysts agree that erroneous network configuration changes, manually entered, cause a significant portion of network downtime and performance degradation.

Estimating Network Proximity and Latency 2007-01-07 01:00:31 Hewlett-Packard

Network proximity and latency estimation is an important component in discovering and locating services and applications. With the growing number of services and service providers in the large-scale Internet, accurately estimating network proximity/latency with minimal probing overhead becomes essential for scalable deployment. Although there exist a number of network distance estimation schemes, they either rely on extensive infrastructure support, require the IP address of the potential targets, falsely cluster distant nodes, or perform poorly with even few measurement errors. This paper proposes Netvigator, a scalable network proximity and latency estimation tool that uses information obtained from probing a small number of landmark nodes and intermediate routers (termed milestones) that are discovered en route to the landmarks, to identify the closest nodes.

Seamless Physical and Virtual Server Management: An Integrated Management Approach 2006-11-16 Opsware

Virtualization is delivering significant benefits to IT organizations that employ virtualized server, storage, and file system solutions. As enterprise demand for new applications and capabilities shows no sign of slowing, neither do most IT budgets show any sign of expanding to match the need. Enterprises are turning to virtualization to maximize platform resources, and the approach is spreading beyond application development and testing labs to production systems--including application and Web server infrastructures. Yet, while virtualized resources help enterprises meet their growing capacity needs, they also pose serious new management challenges. The long-term success of virtualization strategies will depend on how well virtualized systems can be managed.

In addition, vendors are stepping up to support customers' virtualization needs with a broader range of solutions, making it easier to virtualize operations. The original virtualization solution provider, VMware, is now joined by Sun Solaris 10, Microsoft Virtual Server, IBM LPAR, and XenSource. Not only can server resources be virtualized, now they can be virtualized on a wide range of platforms, which leads directly to virtualization's most significant challenge--management.

This whitepaper explains how Opsware can help to manage traditional server environments with the integrated capabilities required to successfully manage virtual server environments as well.

What's New: Finding Significant Differences in Network Data Streams 2006-12-13 01:00:24 Rutgers, State University of New Jersey

Monitoring and analyzing network traffic usage patterns is vital for managing IP Networks. An important problem is to provide network managers with information about changes in traffic, informing them about "What's new". Specifically, the focus of this paper is on the challenge of finding significantly large differences in traffic: over time, between interfaces and between routers. The paper introduces the idea of a deltoid: an item that has a large difference, whether the difference is absolute, relative or variational. It presents novel algorithms for finding the most significant deltoids in high speed traffic data, and proves that they use small space, very small time per update, and are guaranteed to find significant deltoids with pre-specified accuracy.

Stable Egress Route Selection for Interdomain Traffic Engineering: Model and Analysis 2006-12-13 01:00:24 Alcatel-Lucent

This paper presents a general model of interdomain route selection to study interdomain traffic engineering. In this model, the routing of multiple destinations can be coordinated. Thus the model can capture general traffic engineering behaviors such as load balancing and link capacity constraints. The paper first identifies potential routing instability and inefficiency of interdomain traffic engineering. It then derives a sufficient condition to guarantee convergence. The paper also shows that the constraints on local policies imposed by business considerations in the Internet can guarantee stability without global coordination.

Effective Computation of Biased Quantiles Over Data Streams 2006-12-13 01:00:24 Alcatel-Lucent

Skew is prevalent in many data sources such as IP traffic streams. To continually summarize the distribution of such data, a high-biased set of quantiles (e.g., 50th, 90th and 99th percentiles) with finer error guarantees at higher ranks (e.g., errors of 5, 1 and 0.1 percent, respectively) is more useful than uniformly distributed quantiles (e.g., 25th, 50th and 75th percentiles) with uniform error guarantees. This paper addresses the following two problems. First, can a person compute quantiles with finer error guarantees for the higher ranks of the data distribution effectively, using less space and computation time than computing all quantiles uniformly at the finest error? Second, if specific quantiles and their error bounds are requested a priori, can the necessary space usage and computation time be reduced?.

Understanding Systems Management and Deployment Automation 2006-12-12 18:32:48 KACE

As your organization grows, systems management and provisioning isn't going to get any easier - if you follow traditional processes. The right tool can make implementing best practices much easier, but which methodology and features should you look for? Using an Appliance-based Delivery (AbSD) architecture, you can address the issues many mid-sized enterprises face in systems management such as hardware and software inventory, distributing software, patch management, scripting and security management, along with systems provisioning issues around disk imaging, installation, remote systems recovery and application slip streaming. Review this Flash demonstration of tools used to implement best practices for IT Automation.
