Spotting Single Points of Failure in a graph
Enterprise networks should never have Single Points of Failure (a.k.a SPOF) in their daily operation. SPOF in general is an element in a system which, if stopped, causes the whole system to stop. Single failure (or maintenance or misconfiguration) of any network device or link…
Chasing routes in the network
Have you ever tried to find out why the dynamic routing protocol in your network is not passing specific prefix as expected? And the situation had not improved even though ad-hoc static routes were created here and there? Networking protocols (while designed to be simple…
Announcing IP Fabric Platform v2.2
I’m pleased to announce the release of IP Fabric® Platform 2.2. Continuing our mission of delivering more capabilities into the hands of the network engineers, this major release exposes all predefined verification checks and enables to edit them or to define your own. Each technology…
Dynamic Diagrams part 2: persistence
Network engineer/architect can use diagrams to speed up many of his routine tasks — from overview presentation of the network to the detailed troubleshooting of faulty data flow from the client to server. But regardless of the task type, there is always a requirement that the diagram…
Dynamic Diagrams part 1
The best way to get a quick overview of any network infrastructure is by viewing a diagram (or most likely set of diagrams). The human brain can receive essential information much faster when represented in graphical form. The downside is that manually creating a diagram…
Managing changes in the network
Large enterprise networks are constantly changing. Even if no administrative or configuration change activity is planned, the network lives by itself — the devices and links are going up/down and the network protocols are changing their states. How can you find unwanted changes as soon as possible?…
Power over Ethernet endpoints in the IP Fabric platform
Many devices such as IP phones, wireless access points, IP cameras or even small switches may be powered via the data Ethernet cable (by one of the PoE standards). This approach saves a lot of issues with separate electric power infrastructure and eases device manageability…
What’s new in the IP Fabric platform v2.0
The IP Fabric platform 2.0 is a major new version of the network engineer’s best friend. A number of big changes and customer feedback have made it into the release. From tracking all changes in the network to supporting more networking technologies, and going deeper…
Spanning Tree analytics with the IP Fabric platform v2.0
The IP Fabric platform is a network engineer’s best friend when performing deep network audits. For example, to verify root placement for overlapping VLANs in a LAN, I would normally need to look through the STP roots, and painstakingly trace L2 links, reconstructing the topology…
Introducing the IP Fabric platform v2.0
The feature I’ve been waiting for since the beginning of my Network Engineering career is finally here: Dynamic Change Monitoring. It’s finally possible to know the answer to the age-old question “What has changed in the network since yesterday?” and actually get a definitive response…
