Internet Service provider topics, Network operations, and other topics. Some topics include Mikrotik, Cisco, Arista and other configurations.
A little off the beaten path on this one. We are diving into a big part of a Cellular tower deployment. Many sites now use an Active Antenna Unit, or AAU. The radio and the antenna are built into the same enclosure. An AAU combines the antenna, radio transceivers, power amplifiers, and low-noise amplifiers into … Read more
A Python script usually spends very little time doing actual Python work. Most of the actual work comes from libraries that know how to connect to network devices and do the work. They interact with APIs. Once you understand what each library does, you can spend less time writing code and more time solving network … Read more
Python has become one of the most valuable tools in a network engineer’s toolbox. You do not need to write thousands of lines of code or become a software developer to get value from it. If you are kind of old school like me, anything other than bash scripting might be new. In this article, … Read more
RFC 10005 defines a BGP extended community that lets a router attach link bandwidth information to a route. Another router can use that value when it spreads traffic across multiple BGP paths. RFC 10005 matters because links are not always of the same capacity. This RFC provides routers with a standard way to carry bandwidth … Read more
NBASE-T bridges the gap between 1 Gigabit and 10 Gigabit Ethernet by supporting 2.5 Gbps and 5 Gbps over existing copper cabling. Learn how it works, where it makes sense, and what network engineers should look for when deploying and troubleshooting multi-gigabit links.
