Network Vulnerability Assessment

Runbook of the Week: Network Vulnerability Assessment

Hey again, folks! Last week we tackled how Runbook automation can help us perform an MPLS Carrier Assessment. This week, we’re going to outline how a network vulnerability assessment using a Runbook helps you easily confirm that your network devices are accessed-hardened. Once you either complete a network’s initial configuration or take over management of an […]

Runbook of the Week: MPLS Carrier Assessment

Runbooks can be built for any use case, and this week I’m happy to offer yet another example of what all they can do for you. In my last Runbook of the Week post, I discussed how Runbook automation increases the pace, ease, and accuracy of assessing a network’s Layer-2-architecture. Today, we’re going to examine a Runbook that can […]

The Next Generation of Network Automation

Clearly, network automation is essential for organizations to keep up with the accelerating pace of technology and business. However, there are numerous tasks that current automation tools cannot facilitate. Over the last two decades, two limited types of network automation have evolved into mainstream practices to replace some of the manual work for network engineers. […]

Runbook of the Week: Layer-2 Architecture Assessment

Hi again! If you recall, in my last article I discussed how NetBrain’s Runbook automation speeds up the process of assessing and troubleshooting a network’s routing topology. (It also saves you aspirin!) This week, let’s suppose you need to understand the state of your network’s Layer-2 architecture in order to troubleshoot a problem. With NetBrain, […]

Why Faulty Clock Technology Should Be a Warning for Network Engineers

It’s no secret that networks have grown incredibly complex and managing them has turned into a painful task. With the growth of transformational technologies such as software-defined networking (SDN), the Internet of Things (IoT), cloud computing and more, companies are being forced to manage networks that look very different from a decade ago. Today, everything […]

Network Documentation is Hard… but Documentation is Priceless

Network Documentation is Hard… but Documentation is Priceless

Network documentation is great, but documentation is only as good as how accurate it is, if it exists at all. For years network engineers have limped along with an incomplete picture of their networks and the burden of creating and maintaining tedious spreadsheets. Documentation is priceless, but documentation is hard. Several years ago I was […]

Limitations of Traceroute

Limitations of Traceroute

One of the most commonly used tools in troubleshooting is arguably the traceroute. As helpful as this tool is, there are a few critical challenges. Before we look at these, let’s understand traceroute a little more. How it Works: The source (SRC) machine will typically send 3 probe packets towards the destination IP address, starting […]

Runbook of the Week: Troubleshooting Dynamic Routing

Network management isn’t easy. At NetBrain, we understand this, and we’ve designed our network automation platform specifically to help network engineers speed up their network documentation and troubleshooting. A central feature of our platform is executable Runbooks, which allow you to build and automate any troubleshooting process. Twice a month, as part of our ongoing […]
