Aruba switch can cut the need for separate, single-function appliances

Hewlett Packard Enterprise company Aruba is taking the wraps of a new flagship data-center switch aimed at helping to better control and secure hybrid-cloud traffic in the enterprise.The Aruba CX 10000 Series switch is a top-of-rack, L2/3 data-center box with 3.2Tbps of switching capacity, 48 ports of line rate 10/25GbE and six 40/100GbE ports, the company says. But its most intriguing component is an integrated Elba programmable data processing unit (DPU) from Pensando that helps eliminate the need for separate appliances for security and load balancing, for example.The 10 most powerful companies in enterprise networking 2021 Pensando is a startup lead by a crew of ex-Cisco stars including its chairmen of the board, former Cisco CEO John Chambers. Others leaders of the company include former Cisco engineering icons Mario Mazzola, Prem Jain, Luca Cafiero and Soni Jiandani, collectively known as MPLS based on their first initials. The MPLS group has founded a number of companies that were spun back into Cisco during Chamber’s time as CEO including Andiamo Systems for SAN switching, Nuova Systems for data-center switching and Insieme Networks for software-defined networking systems.To read this article in full, please click here

Backwards-compatibility in Cloudflare Workers

Cloudflare Workers is our serverless platform that runs your code in 250+ cities worldwide.

On the Workers team, we have a policy:

A change to the Workers Runtime must never break an application that is live in production.

It seems obvious enough, but this policy has deep consequences. What if our API has a bug, and some deployed Workers accidentally depend on that bug? Then, seemingly, we can't fix the bug! That sounds… bad?

This post will dig deeper into our policy, explaining why Workers is different from traditional server stacks in this respect, and how we're now making backwards-incompatible changes possible by introducing "compatibility dates".

TL;DR: Developers may now opt into backwards-incompatible fixes by setting a compatibility date.

Serverless demands strict compatibility

Workers is a serverless platform, which means we maintain the server stack for you. You do not have to manage the runtime version, you only manage your own code. This means that when we update the Workers Runtime, we update it for everyone. We do this at least once a week, sometimes more.

This means that if a runtime upgrade breaks someone's application, it's really bad. The developer didn't make any change, so won't be watching for Continue reading

Graceful Restart and BFD

The whole High Availability Switching series started with a question along the lines of “does it make sense to run BFD together with Graceful Restart”. After Non-Stop Forwarding 101, Graceful Restart 101, and Graceful Restart and Convergence Speed we finally have enough information to answer that question.

TL&DR: Most probably not.

A more nuanced answer depends (as always) on a gazillion implementation details.

Using the xargs command on Linux to simplify your work

The xargs command on Linux can make it easier to build and execute commands. If you want to run the same command for a group of files or users, xargs can often make that process easier. Here's a very simple example of xargs that creates or updates the update time on some files.$ echo file1 file2 file3 | xargs touch $ ls -l total 0 -rw-r--r--. 1 shs shs 0 Oct 15 12:41 file1 -rw-r--r--. 1 shs shs 0 Oct 15 12:41 file2 -rw-r--r--. 1 shs shs 0 Oct 15 12:41 file3 The command below is similar, but creates a file with blanks in its name because the -d specifies the input termination character.To read this article in full, please click here

Crawler Hints Update: Cloudflare Supports IndexNow and Announces General Availability

In the midst of the hottest summer on record, Cloudflare held its first ever Impact Week. We announced a variety of products and initiatives that aim to make the Internet and our planet a better place, with a focus on environmental, social, and governance projects. Today, we’re excited to share an update on Crawler Hints, an initiative announced during Impact Week. Crawler Hints is a service that improves the operating efficiency of the approximately 45% of Internet traffic that comes from web crawlers and bots.

Crawler Hints achieves this efficiency improvement by ensuring that crawlers get information about what they’ve crawled previously and if it makes sense to crawl a website again.

Today we are excited to announce two updates for Crawler Hints:

1. The first: Crawler Hints now supports IndexNow, a new protocol that allows websites to notify search engines whenever content on their website content is created, updated, or deleted. By collaborating with Microsoft and Yandex, Cloudflare can help improve the efficiency of their search engine infrastructure, customer origin servers, and the Internet at large.
   
2. The second: Crawler Hints is now generally available to all Cloudflare customers for free. Customers can benefit from these more Continue reading
