Seeing Tetration in action – NFD16

At Networking Field Day last month, Amy Arnold saw a presentation on Cisco’s Tetration. The platform uses machine learning to proactively create security policies based on current flow information. Amy was impressed to see that this not only has the ability to predict security policies based on current flows, but that the system can integration with services like Splunk or Phantom to communicate with devices to isolate traffic.


Preserving and managing intent using Apstra AOS

Apstra’s AOS is a platform to allow network engineers to design a network based around an intended purpose or function, rather than muddling with an existing architecture who’s original intent can only be guessed. Amy Arnold points out that AOS simply isn’t a tool for building an initial configuration, but also a way for making revisions in a controlled manner, while documenting intent. This takes intent out of the realm of a network engineers thoughts, and forces it to be explicitly stated in a single source of truth.


Cisco Live 2017, engineering awesomeness

Amy Arnold reflects on her experience at Tech Field Day and Cisco Live US, reviewing OpenGear’s new API, Paessler’s new monitoring solution, and NetApp’s FlexPod SF.


Forward Networks – go ahead, break it

Amy Arnold laments the plight of the network engineer. The agonize over network design, try to come up with every conceivable failover scenario, and then deal with the consequences. Some have the aid of a lab to help test their configuration, most don’t. That’s why what Forward Networks presented at Networking Field Day was so interesting. It allows for you to model over your network in software, and then break it in every conceivable way. Forward’s model shows every a packet can possibly go, allowing the engineer to see exactly how a scenario will play out. She was justifiably concerned about how their product will be priced going forward, but otherwise it seems like a valuable tool in the engineer’s arsenal.


Shiny new NetPath Services

SolarWinds showed off their latest with NetPath at Networking Field Day. Amy Arnold seemed impressed by their solution. NetPath isn’t just a traceroute visualization tool, it uses “real” network traffic from Windows-based pollers on the network. This allows an engineer to get a better sense of how traffic flows, without worrying about packets being dropped (as much) by devices on the network. Amy says it best, “any tool that expands insight into what packets are doing is a beautiful thing.”
