This is the last of three posts about planning, executing, and validating network configuration changes. You can find the first two here and here. Validating Network Configuration Changes This is a critical part of any configuration change. The goal of this phase is to make sure that the work was…
Network tomography is the inference of the internal behavior and topology of a network, based on end-to-end network measurements. Imagine having the ability to probe the network from its edges and reach conclusions about its guts. Similarly, computer tomography allows you to create an image of an object or a human…
This is the second of three posts about planning, executing, and validating network configuration changes. The first post discusses the planning phase of network configuration changes. The last part is coming up in two weeks. Executing Network Configuration Changes This is the day of the launch when the rubber hits…
Network Monitoring Agents “Software is eating the world,” yet “hardware is the new software.” The former doesn’t contradict the latter, but these two statements highlight how the distinction between software and hardware is becoming blurrier and blurrier. In the context of network monitoring, you can find tools that utilize one…
This is the first out of three posts about planning, executing, and validating network configuration changes. The other two posts will be published at distance of two weeks on the NetBeez blog. Validating Configuration Changes It’s not surprising that a great portion of the activities of a network engineer relate…
Troubleshooting Use Cases One of the best ways to show how NetBeez enables network engineers to improve their operations is through the lenses of our customers. For that purpose, we have just published Troubleshooting with NetBeez, which describes the following three use cases: Troubleshooting web application performance problems Determining the…
Somewhere far away, your sprawling enterprise network is on fire (figuratively, hopefully). Help desk is getting swamped, but users are unable to articulate the precise nature of the issues. Since you can’t rely solely on user-reported data, you turn to your monitoring data. But even if you have all the…
Network Complexity Can we measure network complexity? Wikipedia states that network complexity is “the number of nodes and alternative paths that exist within a computer network, as well as the variety of communication media, communications equipment, protocols, and hardware and software platforms found in the network. Wikipedia also defines a…
Networks Are Distributed Enterprise networks are distributed systems by nature which are supposed to operate autonomously after correct deployment and configuration. I want to emphasize the “after correct configuration and deployment” part because if this happens the network engineer’s responsibility is fulfilled and he can go to bed, worry free,…
Pittsburgh, PA – May 13, 2014 – eiNetwork has chosen NetBeez to support its customers at more than 75 library locations in Pittsburgh and Allegheny County. eiNetwork provides network connectivity, online Library Catalog services, PC support for 2,500 desktops, and technology assistance to libraries throughout the county.
