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
AWS ABCs – EC2 Internet Connectivity
So, you’ve created a compute instance (ie, a virtual machine) on Amazon EC2. Next question: does the instance require access to and/or from the Internet?
Protip: just because you created the instance in the public cloud, i.e. the cloud that you get to over the Internet, it doesn’t mean that your instances all need to sit on the Internet. They can have direct inbound and outbound Internet access, no Internet access, or something in between (which I’ll explain).
The basic building block for networking on AWS is the VPC (Virtual Private Cloud). Within a VPC, you define your IP space, gateways, ACLs, DHCP options, and more. Gateways will be the focus of this article.
TL;DR
- Internet Gateway == static NAT: 1-to–1 mapping between the private IP address assigned to an instance and a public IP address that gets assigned to the instance. Note this implies that NAT works in both directions (in- and outbound) and enables direct reachability to the instance from the Internet via its public IP address.
- NAT Gateway == NAT overload, aka port address translation: all instances behind the NAT Gateway are mapped to a single public IP address.
- No gateways == no NAT! No Internet Continue reading
Get a head start with QUIC
Today Cloudflare opened the door on our beta deployment of QUIC with the announcement of our test site: cloudflare-quic.com. It supports the latest draft of the IETF Working Group’s draft standard for QUIC, which at this time is at: draft 14.
The Cloudflare Systems Engineering Team has a long history of investing time and effort to trial new technologies, often before these technologies are standardised or adopted elsewhere. We deployed early experiments in standards such as: HTTP/2,
TLS1.3, DNSSEC, DNS over HTTP, Encrypted SNI, when they were still in incubation. We committed to these technologies in their very early stages because we believed that they made for a safer, faster, better internet. And now we’re excited to do the same with QUIC.
In this blog post, we will show you how you can unlock the cloudflare-quic.com achievement and be some of the first people in the world to perform a HTTP transaction over the global internet using QUIC. This will be a moment that you can tell your grandkids about - if they can stop laughing at your stories of cars with wheels and use of antiquated words like: “meme” and Continue reading
