The Roaring Penguin Training Network

A recent paper presented evidence that Bayesian filtering could be effective using a shared Bayes database, even among hundreds or thousands of different users. This lead to the Roaring Penguin Training Network (RPTN), a mechanism for sharing Bayes votes among different CanIt customers. This white paper describes the Roaring Penguin Training Network (RPTN).

Reduce the Risk of Network and Application Performance Issues

More than ever before, the IT network is a strategic asset to a business, and any downtime or degradation in network or application performance can directly impact an organization’s bottom line. This white paper looks at a methodology for solving network and application performance issues and outlines a new approach to getting to their root causes more quickly. Read More

Counting the Cost of Network Efficiency

It is hard to quantify the costs of poor network or application management, but they include lost productivity due to time spent fixing problems and increased capital and operating expenses. But when creating IT budgets, organizations need to consider the impact of investment in network and application management on overall revenues. IT efficiency should be a priority item for any corporate agenda, and executives need to understand that the network is not only a core part of what their organization does, but plays a key role in achieving business goals.

There is actually a direct correlation between network performance and application performance. There is of course intrinsic value in network hardware and software, but more importantly many people in the organization rely on the applications that the network supports—so if the network is running slowly, users’ applications will slow down too. Hence a budget priority should be where changes in the network are needed to avoid problems arising or improve application performance and hence overall productivity.

This white paper makes a case for the organizational need for solutions and tools which provide network performance information and help identify problems and their causes and areas where improvements should be made, making it possible for budgetary decisions to be based on performance data. It looks at questions the IT team needs to ask to get to the heart of network problems and find the best solution, as well as three categories of network improvements, and also details how an AANPM, or application aware network performance management solution, takes an application-centric approach to network issues and can lead to faster problem solving, reducing downtime, increasing productivity, and saving troubleshooting time.  Read More

Put the Customer First: Managing the User Experience

Customers are demanding increasingly high levels of service—they want what they want, as soon as they want it. Networks need to be faster than ever, and more reliable, to satisfy exacting customer standards.

While organizations often rely on a patchwork of network resources to deliver their services, customers expect their experience to be seamless. Network managers need to monitor those resources more proactively for a holistic view that considers network availability, network performance, and service quality. This demands a shift in focus from hardware to a deeper understanding of service provision and the customer experience. It also requires an evolved skill set, and new application-monitoring tools.

This white paper explores the evolution of networks, including the idea of user-centric networks and network virtualization, and the technology that will support it. Read More

E-mail 101

The first e-mail programs were created in the late 60s/early 70s—simpler times, when everyone on the network was trustworthy. Even knowing what we know today about spammers, we still tend to take e-mail for granted, and trust it far more than it deserves. Learn about the components of the e-mail system, understand how e-mail moves on the Internet, and find out how to interpret e-mail message headers. Read More
