A Day in the Life of a Packet

Al Rasheed is back with another excellent write up from a Field Day presentation, this time focusing on what he saw from Forward Networks at Tech Field Day Extra at Cisco Live Europe this year. The intent-based networking company focused on their Forward Enterprise tier on the presentation, showing use cases for Application Team Self-Service and Change Window Assistance. Al was really impressed by how well prepared the presenters are, and agrees with Ivan Pepelnjak that the presentation was “awesome”.


Forward Networks: Bringing Sanity to a Network Near You

Max Mortillaro isn’t exactly a networking guy, so it takes a lot for him to have a “wow” moment when hearing from them. That’s just what he got from Forward Networks during their presentation at Tech Field Day Extra at Cisco Live Europe 2019. They showed off their Enterprise offering, which builds on a free mapping tier and adds Verification, Prediction, Comparison and Integration features. You’ll have to check out their presentation for all the details, but Max found it very impressive.


Tech Field Day Extra @ CLEUR19 Recap

Cisco Live Europe is an event big enough that it’s tough to encapsulate in any one post. That’s why it’s great to have smaller, more focused looks, especially when it comes from Ivan Pepelnjak. He wrote up a posting looking at what he saw from Tech Field Day Extra at Cisco Live Europe. Cisco touched on automating Meraki deployments, new AWS-focus Cisco ACI features, HyperFlex updates, and more. Be sure to read Ivan’s thoughts on what he saw, and watch the presentation video for yourself.


Automated Testing & Intent Verification for Network Operations

Jason Edelman considers why networks often lack the robust testing tools that are the bedrock of software development. He recently saw a solution from Veriflow at Networking Field Day that might move networking closer to having better preemptive testing. They offer built in consistency and intent-based checks to define the state of the network and when something appears out of compliance. He also likes that their platform exposes all of this functionality via a RESTful API.


Assuring your network will do what you think it…

Tim Miller wrote up his thoughts on what he saw from Forward Networks at Networking Field Day last year. Their solution is billed for providing network assurance, which they break down into correctness and performance. Their presentation focused on correctness, which they use sophisticated modeling to formally verify. Tim reviews the implications of their Forward Platform in terms of business intent, highlights their strong search functionality, and predication engine.


NFD13: Forward Networks Comes Out of Stealth to Impress

Peter Welcher reviews what he saw from Forward Networks once they came out of stealth. Peter seemed impressed with how Forward is able to put together a database model of network configurations that can be searched and indexed independent of actually operating on the network. This can then be used for fast troubleshooting, as well as testing configurations to make sure they’re operating within a desired state. Overall, Peter sees this as a way to not spread you senior enterprise talent too thin. While there isn’t any automated remediation backed in, the powerful forecasting tools they present make it possible to better utilize talent in your organization.


Forward Thinkers, Forward Networks

Rob Coote shares his impressions from what he saw with Forward Networks at Networking Field Day last month. He really highlights how Forward’s software modeling of network performance could impact, not just the performance of the network, but the worth routines of network engineers. By effectively giving you a network lab to tinker with in software, their solution theoretically eliminates the “wait-and-see” approach to changes in a network. Rob really hopes they are able to move their solution beyond just monitoring to remediation. But he makes a really great point on the very human impact Forward Networks could have.


The Quest for Verification with Forward Networks

Forward Networks gave a presentation fresh out of stealth mode at Networking Field Day, and it certainly made an impression with Rich Stroffolino. He outlines how the company is doing their network monitoring. They model all possible places a packet can go on a network in a constantly updating software model. This allows you to not only react when problems occur, but also for better planning and provisioning, since you can model traffic very accurately in the software model. We’ll wait to see how their solution gets deployed in an actual enterprise, but on a theoretical level it’s fascinating.


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.


State of the Industry: Network Analytics

Gestalt IT just debuted a new feature, a weekly State of the Industry post. For their first week, they’re looking at the state of network analytics. They take a look at two competing methodologies to the problem. The first is SolarWinds NetPath tool, which sits in the network. The SolarWinds approach seems to take the ideas behind existing tools, and looks to perfect them. The other method is Forward Networks, which is presenting a top-down approach to do live mapping purely in software. Both are interesting, and point to further investment and development in the space going into 2017.
