Native or Open-source Data Models? Use Both for Software-Defined Enterprise Networks.
Why using a mixed schema approach using native and open-source data models is possible and makes sense for enterprise networking programmability and automation.
Native, IETF, OpenConfig… Why so many YANG models?
Which YANG model to use for your project? Ask Hank takes a look at your options, and how model driven programmability is a foundational technology for the automation engineer.
Telemetry in Action: NETCONF and gNMI with a Custom-Built Collector!
Model-Driven Telemetry Telemetry is used to subscribe to meaningful data and measurements from remote devices and transport it to a receiving system for monitoring and analysis. This data allows network administrators to proactively visualize their network, and helps them automate tasks and forecast capacity requirements. When we talk about streaming telemetry, we typically refer to […]
Network Automation and the Ingenuity of Data Models
Explore two new methods of network automation in NX-OS using a model-based approach.
Hot off the press: Introducing OpenConfig Telemetry on NX-OS with gNMI and Telegraf!
Learn how to set up streaming telemetry with gNMI on your Cisco Nexus switches and stream it to an open source collector.
Boring is the New Awesome
The core principle of model-driven telemetry is super simple: as much usable data out of the network as fast as possible. The implementation is also pretty subtle: a push mechanism, data models, open-source encodings. In fact, it’s all so simple and subtle that some folks look under the hood and say, “so what?” To that, […]
Oh, How Far We’ve Come in Building Cloud-Scale Networking
It’s been a year since I wrote this blog detailing our software innovations aimed at helping Service Providers address the ever-increasing challenges imposed by digitization. IOS XR for cloud-scale networking has really taken flight since then and I am proud to share with you some highlights from the journey thus far. Our strategy is essentially […]
What’s So Special About Model-Driven Telemetry?
Telemetry and analytics are all the rage in networking today. The industry is abuzz with the potential unlocked by streaming vast quantities of operational data. But what’s so special about “model-driven” telemetry? Models enable networking devices to precisely describe their capabilities to the outside world: what kind of data they expose (e.g. interfaces statistics, configuration […]
