Veriflow at NFD16: Continuous Network Verification

Veriflow presented at Networking Field Day earlier this year, demonstrating their formal verification of enterprise networks. Pete Welcher considers how this enables for continuous checking of network state, and enables intent-based features for network engineers.


Pluribus Networks… 2 Years Later

Pluribus Networks was a returning presenter for Ivan Pepelnjak, who first saw them at Networking Field Day in 2015. Overall this was the company’s fourth Networking Field Day presentation. Make sure to check out our full video coverage from their most recent appearance!


Pluribus Networks at NFD16

Pete Welcher wrote up his post to wrap his mind around where Pluribus Networks falls in the fabric management market. The company differentiates itself with a controller-less design running their Netvisor OS on whitebox switches. Pete liked their framework of managing a fabric as one large switch, rather than many individual devices.


Pluribus Networks – Whitebox Fabric

Daniel Kuchenski reviews what he saw from Pluribus Networks at Networking Field Day in September. He focuses on their Netvisor OS and the possibilities it opens for whitebox hardware. Overall he found it a very flexible solution, with robust management and network virtualization capabilities.


Pluribus Networks Is the Definition of “Software Defined”

Tom Hollingsworth looks at how the value of software-defined networking can drive your network forward with Pluribus Networks. For Tom, SDN is about making the hardware less important than what running on top of it. Pluribus showed how their SDN platform can still provide differentiation on newer hardware.


E Tu Pluribus Networks UNUM?

Pluribus Network gave a brief overview of their analytics platform at last month’s Networking Field Day. Rich Stroffolino was impressed that this capability is baked in at the kernel level, which allows for enabling the analytics services without sacrificing performance.


BiB007: Kentik Network Peering & Capacity Planning

On a recent episode of the Briefings in Brief podcast, Ethan Banks looks back at what he saw from Kentik at Networking Field Day last month. This includes a discussion of their full resolution network analytics, with a specific application for peering and service providers.


BiB009: Pluribus Insight Analytics Platform

On an episode of the Briefings in Brief podcast, Ethan Banks discusses what he saw from Pluribus Networks at Networking Field Day last month. This includes not only their switching portfolio, but their Insight Analytics platform.


AOS Bridging Two Worlds

At Networking Field Day last month, Apstra showed off version 2.0 of AOS, with a focus on how the OS can be used by developers. Previously Apstra had focused on operation applications of AOS, but with this new persona developers are able to create sophisticated AOS application products for operators to use on the platform. In this piece, Apstra’s Jeremy Schulman makes the case that this allows for businesses to stay agile and help operations and develops stay in step across network functions.


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.


Apstra: Networking by Intent

Pete Welcher got to see more from Apstra at last month’s Networking Field Day. The company is pushing back on other companies jumping on the intent-based networking bandwagon, calling it “intent washing”. Pete remains impressed that the company clearly defines what they mean by intent, remain firmly hardware agnostic, and approaching their intent fabric as a single managed entity. This presentation focused on how developers can use Apstra’s intent-based features, which impressed Pete with the versatility for a number of different network roles.


NFD16 day two – Cisco Project Starship a.k.a. Intersight

Gian Paolo Boarina takes a look at the debut of Cisco Intersight, which he saw at Networking Field Day last month. This allows for admins to manage remote servers via a Cisco SaaS portal, including UCS B-Series servers, C-Series servers, and HyperFlex. Gian sees as allowing MSPs and system integrators to more easily scale, as they can monitor and manage their servers through a single dashboard.


Is the Data-Driven Network Next Step in Networking?

First we had software-defined network as the buzzword de rigueur. More recently intent-based networking has increasingly crept into marketing parlance. But Terry Slattery thinks he might have found a new network paradigm at work, one that has so far escaped buzzwordification. He postulates the data-driven network, which would use real time big data analytics on raw network traffic, and then use the results to optimize the network. Terry cites Cisco Tetration, Arista Networks, Apstra, and Veriflow Systems as example, all of which he saw at Networking Field Day last month.


Kentik Finds Truth in the Traffic

Pete Welcher did his homework before seeing Kentik’s presentation at Networking Field Day last month. He watched their prior presentations and was familiar with the company’s offerings. After all that, the company managed to impress Pete with their latest appearance. Read the full post for his detailed impression, but overall, Pete liked that Kentik allows for quick usability with built-in queries and reports, with actual anomaly detection, rapid reporting, and data collection across appliance silos.


Intent-Based Analytics: What is it?

After their presentation at Tech Field Day last month, Apstra’s Sasha Ratkovic shares a post defining intent-based analytics. Their solution is based around formally defining a single source of truth from which you can reason about the presence of change. This allows for analytics based on that criteria, rather than a constantly fluctuating current state.


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.


Arista’s Programmability Strategy

Jason Edelman takes a look at the five components of Arista’s programmability strategy, as presented at Networking Field Day last month. These include EAPI, OpenConfig, NetDB Streaming, Turbines, and EosSdk. Jason breaks down each, weights the merits of the approach, and concludes with how he’d like to see Arista evolve their roadmap down the road.


NFD16 day two – Apstra

Apstra defines “intent” for their IDN solution as “the definition of the expected outcome”. After seeing their Networking Field Day presentation, Gian Paolo Boarina appreciated their ease of use, without sacrificing important features like robust configuration validation. Instead of merely backing up different device configuration throughout the network, Apstra has designed a “snapshot of intent” that generates configurations as needed to fit it. Its a powerful model, albeit one that calls for substantial trust.


Intent-Based Networking: What is it?

Apstra’s Sasha Ratkovic posts about what exactly is intent-based networking, based on their recent presentation from Networking Field Day. He reviews why organizations should be motivated to implement IBN, defines what Apstra specifically means by “intent”, and outlines how such an adoption can fundamentally lead to more agility and availability for your network.


Pluribus Networks… Wait, where are we again?

Although he had followed the company for a while, Chris Marget appreciated an update on Pluribus Networks at Networking Field Day. While he appreciated the company’s use of Solaris to back Netvisor switching OS, the introduction of Netvisor on Linux is a welcome addition. It allows you to manage network devices using specific protocols through a single device via their Netvisor Fabric. One of the other standouts was Pluribus Networks’ “fantastic telemetry and flow analytics capabilities”.
