DPU-Based Smart Interfaces And The Future Of Network Functions And Security At The Edge

This article was originally posted on Packet Pushers Ignition on April 26, 2021. Data center virtualization exacerbated problems for network security designs that relied on a handful of appliance-based (whether physical or virtual) control points, which typically focused on external threats. With advanced persistent threats (APTs) that focus on compromising internal systems, security strategies must […]

Landscape of API Traffic

In recent years we have witnessed an explosion of Internet-connected applications. Whether it is a new mobile app to find your soulmate, the latest wearable to monitor your vitals, or an industrial solution to detect corrosion, our life is becoming packed with connected systems.

How is the Internet changing because of this shift? This blog provides an overview of how Internet traffic is evolving as Application Programming Interfaces (APIs) have taken the centre stage among the communication technologies. With help from the Cloudflare Radar team, we have harnessed the data from our global network to provide this snapshot of global APIs in 2021.

The huge growth in API traffic comes at a time when Cloudflare has been introducing new technologies that protect applications from nascent threats and vulnerabilities. The release of API Shield with API Discovery, Schema Validation, mTLS and API Abuse Detection has provided customers with a set of tools designed to protect their applications and data based on how APIs work and their challenges.

We are also witnessing increased adoption of new protocols. Among encryption protocols, for example, TLS v1.3 has become the most used protocol for APIs on Cloudflare while, for transport protocols, we Continue reading

Hashing out the hash command on Linux

When you type “hash” on a Linux system, you could get one of two very different responses depending on the shell you are using.If you are using bash or a related shell such as ksh, you should see a list of the commands that you have used since your terminal session began, sometimes with a count of how many times each command was used. This can be more useful than using the history command if you just want to see your very recent command activity, but the hash command is not a single executable. Instead, it relies on your shell.How to tell if you're using a bash built-in in Linux hash in bash Here’s an example of the hash command run in bash:To read this article in full, please click here

Three Dimensions of BGP Address Family Nerd Knobs

Got into an interesting BGP discussion a few days ago, resulting in a wild chase through recent SRv6 and BGP drafts and RFCs. You might find the results mildly interesting ;)

BGP has three dimensions of address family configurability:

• Transport sessions. Most vendors implement BGP over TCP over IPv4 and IPv6. I’m sure there’s someone out there running BGP over CLNS¹, and there are already drafts proposing running BGP over QUIC².
• Address families enabled on individual transport sessions, more precisely a combination of Address Family Identifier (AFI) and Subsequent Address Family Identifier.
• Next hops address family for enabled address families.

Meta plans the world’s fastest supercomputer for AI

Facebook’s parent company Meta said it is building the world's largest AI supercomputer to power machine-learning and natural language processing for building its metaverse project.The new machine, called the Research Super Computer (RSC), will contain 16,000 Nvidia A100 GPUs and 4,000 AMD Epyc Rome 7742 processors. It has 2,000 Nvidia DGX-A100 nodes, with eight GPU chips and two Epyc microprocessors per node. Meta expects to complete construction this year.World's fastest supercomputer is 3x faster than No. 2 RSC is already partially built, with 760 of the DGX-A100 systems deployed. Meta researchers have already started using RSC to train large models in natural language processing (NLP) and computer vision for research with the goal of eventually training models with trillions of parameters, according to Meta.To read this article in full, please click here

Introducing New NSX Upgrade Capabilities for NSX-T 3.2

We’re introducing new capabilities to help our customers prepare for upgrading to the latest releases — now available with NSX-T Data Center 3.2.0.1.

To ensure that existing NSX deployments can be successfully upgraded to NSX-T Data Center 3.2.x, we have provided an NSX Upgrade Evaluation Tool that operates non-intrusively as a separate downloadable tool to check the health and readiness of your NSX Managers prior to upgrade. Using NSX Upgrade Evaluation Tool can help avoid potential upgrade failures and save time by avoiding a rollback from a failed upgrade.

Customers upgrading to NSX-T 3.2.x are strongly encouraged to review the Upgrade Checklist and run the NSX Upgrade Evaluation Tool before starting the upgrade process.

In what follows, we’ll go over the details of the NSX Upgrade Evaluation Tool:

• How the tool works
• When to use the tool
• What the tool can and cannot do
• How to use the tool

How the NSX Upgrade Evaluation Tool Works

The main component of the NSX Upgrade Evaluation Tool is the database where a copy of NSX objects will be stored. The tool starts by making a secure copy of the database from an existing NSX Manager Continue reading
