Infrastructure-as-Code Tools
This is the fourth blog post in “thinking out loud while preparing Network Infrastructure as Code presentation for the network automation course” series. Previous posts: Network-Infrastructure-as-Code Is Nothing New, Adjusting System State and NETCONF versus REST API.
Dmitri Kalintsev sent me a nice description on how some popular Infrastructure-as-Code (IaC) tools solve the challenges I described in The CRUD Hell section of Infrastructure-as-Code, NETCONF and REST API blog post:

It has been a trade-off between waiting long enough to have the key sentinel mechanism deployed in sufficient volume in resolvers to generate statistically valid outcomes and yet start this measurement prior to the planned roll of the KSK on 11th October 2018. These are early results, and reflect less than one week of measurement, but some strong signals are evident in the data.HPE Selects Intel Programmable Card for Data Center Servers
HPE is the first original equipment manufacturer to incorporate the programmable card into its devices.

This information is extremely useful, allowing traffic analytics software to combine telemetry obtained from network devices with information obtained using the Microsoft REST API in order to identifying clients, links, and devices carrying the traffic, as well as any issues, such as link errors, and congestion, that may be impacting performance.

New York City Groups Take Broadband into Their Own Hands
A handful of groups in New York City are bypassing large ISPs and building their own community networks, as a way to provide cheaper, and in many cases faster and more reliable service.
NYC Mesh and Silicon Harlem, both about five years old, are among a handful of community-based network providers that are working to provide Internet connection alternatives in New York City. The projects seek to fill in coverage gaps – in terms of both geography and reliability – plaguing incumbent broadband providers.
The nonprofit NYC Mesh, with about a dozen core volunteers and no full-time employees, provides and combination of fiber and wireless Internet access in downtown Manhattan, a large chunk of Brooklyn, and corners of the Bronx and Queens, says organizer Brian Hall.
A monthly payment for service – with average speeds of 80 Mpbs and up to 200 Mbps for some users – is voluntary. Many residential members choose to pay $20 a month, while many businesses pay between $50 and $100, but it’s not required.
Volunteers were inspired to launch the service for a number of reasons, Hall says. They wanted to close the digital divide by providing inexpensive broadband service, and Continue reading
