Competitors rush to fill the vacuum of choice with alternative, interchangeable products. The IT market typically fosters competition […]

Hello Ellen,
I have received a number of these spam messages over the past few weeks and I had hoped they would eventually taper off. However, it doesn’t appear that is the case. So I’ll take the direct approach.
I’m a member of the CCIE Advisory Council. Which means I am obligated to report any and all attempts to infringe upon the integrity of the exam. As you have seen fit to continue to email me to link to your site to promote your test dumps I think you should be aware that I will be reporting you to the CCIE team.
Good luck in your future endeavors after they shut you down for violating their exam terms and conditions. And do not email me again.
That’s an actual email that I sent TODAY to someone (who probably isn’t really named Ellen) that has been spamming me to link to their CCIE dump site. The spam is all the same. They really enjoy reading a random page on my site, usually some index page picked up by a crawler. They want me to insure a link to their site which is a brain dump site for CCIE Continue reading
Chances are you might have heard of io_uring
. It first appeared in Linux 5.1, back in 2019, and was advertised as the new API for asynchronous I/O. Its goal was to be an alternative to the deemed-to-be-broken-beyond-repair AIO, the “old” asynchronous I/O API.
Calling io_uring
just an asynchronous I/O API doesn’t do it justice, though. Underneath the API calls, io_uring is a full-blown runtime for processing I/O requests. One that spawns threads, sets up work queues, and dispatches requests for processing. All this happens “in the background” so that the user space process doesn’t have to, but can, block while waiting for its I/O requests to complete.
A runtime that spawns threads and manages the worker pool for the developer makes life easier, but using it in a project begs the questions:
1. How many threads will be created for my workload by default?
2. How can I monitor and control the thread pool size?
I could not find the answers to these questions in either the Efficient I/O with io_uring article, or the Lord of the io_uring guide – two well-known pieces of available documentation.
And while a recent enough io_uring
man page touches on the Continue reading

Continuing our series on how vendors build networking products, Mike Bushong joins this episode of the Hedge to discuss the overall process, the importance of the product manager, and the importance of managing and selling change. Join Tom Ammon, Eyvonne, and Russ White as we discuss how vendors build products.
A recent decision from the Austrian Data Protection Authority (the Datenschutzbehörde) has network engineers scratching their heads and EU companies that use Google Analytics scrambling. The Datenschutzbehörde found that an Austrian website’s use of Google Analytics violates the EU General Data Protection Regulation (GDPR) as interpreted by the “Schrems II” case because Google Analytics can involve sending full or truncated IP addresses to the United States.
While disabling such trackers might be one (extreme) solution, doing so would leave website operators blind to how users are engaging with their site. A better approach: find a way to use tools like Google Analytics, but do so with an approach that protects the privacy of personal information and keeps it in the EU, avoiding a data transfer altogether. Enter Cloudflare Zaraz.
But before we get into just how Cloudflare Zaraz can help, we need to explain a bit of the background for the Datenschutzbehörde’s ruling, and why it’s a big deal.
The GDPR is a comprehensive data privacy law that applies to EU residents’ personal data, regardless of where it is processed. The GDPR itself does not insist that personal data must Continue reading
Remington Loose sent me an interesting email describing his views on the right approach to network automation after reading my Network Reliability Engineering Should Be More than Software or Automation rant – he’s advocating standardizing network services and cleaning up your network before trying to deploy full-scale automation.
I think you are 100% right to start with a thorough cleanup before automation. Garbage in, garbage out. It is also the case that all that inconsistency and differentiation makes for complexity in automation (as well as general operations) that makes it harder to gain traction.

On the 10th of February (next week) I’m participating in a panel discussing—
A networking strategy involving disaggregation deployment, overlay network virtualization, automation, and visibility can remedy the complexities with better utilization and performance and ultimately enable network slicing and self-healing abilities. Cloudification of the network is here, but how far do we need to go, and what is the impact on the hardware?
The Packet Pushers are launching a new video series with Michael Levan on cloud engineering for network pros. The first video in the series gets into the basics of cloud networks. Michael covers AWS and Azure in particular. You can watch the video below, or click here to see it on YouTube. You can subscribe […]
