To solve the next challenge of autonomous networks, it’s not sufficient to configure YANG data models, it’s not sufficient to stream telemetry, it’s important to close the loop (hence the […]
Just back from the IETF 115 in London last week. While the previous two IETF meetings in Vienna and in Philly were kind of “tentative” physical meetings in the post-COVID […]
The “Data Mesh” concepts are discussed in many different places recetnly, so I decided to read the “Data Mesh: Delivering Data-driven Value at Scale” reference book, by Zhamak Dehghani. “This […]
Network automation is important, as I’ve been stressing for years. See for example this blog: “Automation is as good as your data models, their related metadata, your toolchain, and what you […]
A network administrator needs to monitor network and services as a whole, across multiple use cases, domains, and technologies. For example, a cloud-native video application, running in the VMs/containers on […]
I applaud the vast quantity of knowledge and trainings posted on the Internet lately. Knowledge is shared to whomever is motivated to learn. No more excuses, as online trainings remove […]
The services become more and more complex, with a mix of networking (virtual networking) functions at the edge, the core, and the data center, and the combinations of networking, compute, […]
Reflecting about automation lately, I realized that the messaging changed along the years, the more we learned about networking service automation. About 10 years ago, I used to make the […]
In 2014, work on “Requirements for Subscription to YANG Datastores” started at the IETF, eventually finalized as RFC 7923. This document provides the telemetry foundational set of requirements for a […]
Network Service YANG Modules [RFC8199] describe the configuration, state data, operations, and notifications of abstract representations of services implemented on one or multiple network elements. Quoting RFC8199: “Network Service YANG […]
