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…
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…
