NSX-T Edge Transport Node Packet Capture

NSX-T v3.0.1 and v3.1.3 were used to try the stuff described below As always with network engineers, even when working with SDN/SSDC solutions, sooner or later you will be asked to troubleshoot connectivity across your hops. And if working with VMware NSX-T platform, your next-hop for the North-South Datacenter traffic will almost always be NSX-T EDGE Transport Node VM. It will be really useful then to be able to get some packet traces out of that box in order to troubleshoot the traffic issues in detail. One of the examples would be simple routing or some sort of Loadbalancing traffic

Increased interest in Spanish media after the La Palma volcanic eruption

The Internet is a valuable source of knowledge but also a deeply interesting, interconnected, and complex place. And with Cloudflare Radar (our Internet trends and insights free tool for everyone — including journalists, like I was for several years) you get a sense of different trends in the collection of networks that form the Internet.

We saw that over the past week or so in Spain. Radar shows a clear increase in interest in Spanish media outlets (in comparison with the preceding days and Sundays) after the news of the eruption in La Palma (one of the Spanish Canary Islands) broke on Sunday, September 19.

That is particularly clear looking at El País, one of the most well known media outlets in the country. Using our Global Popularity Ranking Trend available on Radar, we can see that ElPais.com jumped several positions in our ranking of most popular domains after September 19. That change is clear in the last seven days, but especially in the last 30, putting El País near the top 3,000 most popular domains in the world.

Reusing Underlay Network for Infrastructure Services

Boris Lazarov sent me an excellent question:

Does it make sense and are there any inherent problems from design perspective to use the underlay not only for transport of overlay packets, but also for some services. For example: VMWare cluster, vMotion, VXLAN traffic, and some basic infrastructure services that are prerequisite for the rest (DNS).

Before answering it, let’s define some terminology which will inevitably lead us to the it’s tunnels all the way down endstate.

How Cloudflare provides tools to help keep IPFS users safe

Cloudflare's journey with IPFS started in 2018 when we announced a public gateway for the distributed web. Since then, the number of infrastructure providers for the InterPlanetary FileSystem (IPFS) has grown and matured substantially. This is a huge benefit for users and application developers as they have the ability to choose their infrastructure providers.

Today, we’re excited to announce new secure filtering capabilities in IPFS. The Cloudflare IPFS module is a tool to protect users from threats like phishing and ransomware. We believe that other participants in the network should have the same ability. We are releasing that software as open source, for the benefit of the entire community.

Its code is available on github.com/cloudflare/go-ipfs. To understand how we built it and how to use it, read on.

A brief introduction on IPFS content retrieval

Before we get to understand how IPFS filtering works, we need to dive a little deeper into the operation of an IPFS node.

The InterPlanetary FileSystem (IPFS) is a peer-to-peer network for storing content on a distributed file system. It is composed of a set of computers called nodes that store and relay content using a common addressing system.

Nodes communicate with each other Continue reading

The new internet speed record twice as fast as the old one

Everyone wants faster internet speeds. Even people who already have high-speed connections want faster internet, including enterprise workers and IT pros. More speed is what they need, or at least what they would strongly prefer, because the faster data is transmitted between two devices, the faster decisions can be made and actions taken. In the Darwinian digital economy, slow Internet speeds are for laggards and also-rans!So how fast is fast? Some might say the average US internet speed of 99.3 Mbps as measured earlier this year by HighSpeedInternet.com is more than adequate, while an enterprise with a sizable workforce and growing number of connected devices and edge networks would need far more bandwidth.To read this article in full, please click here

IAB Workshop on Measuring Network Quality for End Users

The telephone network had a single task: make human voice conversations work well. IP networks have a more challenging objective: make all kinds of digital transactions work well. From first player shooter games, though video streaming and web transactions through to human conversations. Make 'em all work well. This topic has become one of those long-standing sagas in IETF folklore, and another chapter of the evolving story was written at a recent IAB Workshop on Measuring Network Quality for End Users. Here's my impressions of this workshop.

Pure Storage Breaks into Storage-as-Code, Data Services

The cloud era started off with the belief that, eventually, enterprises would migrate all of their workloads to the public cloud — drawn by the promises of greater flexibility and agility, cost reductions, manageable OPEX payment models, and the ability to shift responsibility for management of IT environments to the cloud providers themselves. …

How Your Network Can Solve Your Digital Dilemma

In the drive to successful transformation, the underpinning computer network on which that change relies is taken for granted to just magically deliver what is needed. But that’s a strategic mistake, suggests Lars Rossen of Micro Focus, who wants the network treated as a product.

Hedge 102: BGP Security with Geoff Huston

Our community has been talking about BGP security for over 20 years. While MANRS and the RPKI have made some headway in securing BGP, the process of deciding on a method to provide at least the information providers need to make more rational decisions about the validity of individual routes is still ongoing. Geoff Huston joins Alvaro, Russ, and Tom to discuss how we got here and whether we will learn from our mistakes.
