ISDN, while an old technology, is still around in many parts of the world. When will it go away? George Michaelson joins Tom Ammon and Russ White to discuss the end of ISDN. The conversation then veers into old networking technologies, and the importance of ISDN in setting the terms and ideas we use today—ISDN is one of the key technologies around which network engineers built their mental maps of how to build and maintain networks.
This episode on Python for networking covers the lab topology we’ll be working with in VIRL, choosing a text editor, and basic lab configurations.

Anyone who’s ever gone to a networking event knows that they can be exhausting. You’re constantly meeting new people, exchanging business cards, and trying to make a good impression. It’s no wonder that so many people end up burning out quickly.
The key to networking effectively is actually quite simple: getting a good night’s sleep beforehand.
Most people need around eight hours of sleep per night to function at their best. However, if you know you have an upcoming networking event, it’s important to get even more sleep than usual. Try to get at least nine or ten hours of sleep the night before. This will help ensure that you’re well-rested and won’t be as likely to feel exhausted during the event.
There are a few different things you can do to make sure you get enough sleep. First, avoid caffeine in the evening. Caffeine can stay in your system for up to eight hours, so it’s best to avoid it after lunchtime.
Second, establish a bedtime routine and stick to it as much as possible. Continue reading
Red Hat Insights is a suite of cloud services available on the Red Hat Hybrid Cloud Console, powered by an expert system that is built upon years of data collected from across Red Hat’s worldwide customer base. For Red Hat Ansible Automation Platform customers, it provides predictive analytical reporting of your Ansible automation.
This blog breaks down the new reports that analyze module usage within the Ansible Automation Platform.
In summary, module usage is really important because modules can contain security vulnerabilities and require updates to support new integrations of hardware or software. It is paramount to know which modules you are using in your automation.
Let's look at each report and what each of them can deliver for you.
Description: The number of job template and task runs, grouped by Ansible module usage.
Use Case: You can use this report to discover which modules are being used the most across your automation, helping you to check things like organization-wide adoption of purpose-built modules over potentially less performant, catch-all solutions.
Example:
This chart shows how the file and gather_facts modules are the most used, but also shows that over the past 6 Continue reading
We are excited to announce that as of today, network security teams can procure and use Magic Transit, Cloudflare’s industry-leading DDoS mitigation solution, and Kentik’s network observability as an integrated solution. We are excited to help our customers not just with technical simplicity, but business process simplicity as well.
Distributed Denial of Service (DDoS) attacks are highly disruptive to businesses everywhere. According to the Cloudflare DDoS Attack Trends report, in the first half of 2021 the world witnessed massive ransomware and ransom DDoS attack campaigns that interrupted critical infrastructure, including oil pipelines, healthcare, and financial services. In the second half, we saw a growing swarm of attacks, including one of the most powerful botnets deployed (Meris), with record-breaking network-layer attacks observed on the Cloudflare network.
Along with an increase in severity, there is a proliferation of automated toolkits that make it simple and cheap for anyone to launch these attacks. Detecting and stopping these attacks manually is not effective, and network security engineers are increasingly turning to automated tools to help ensure network and application availability.
DDoS protection has evolved over the years from appliances to hybrid models to fully Internet-native solutions, like Continue reading
Headlines about ‘great resignation’ tend to ignore that people are moving jobs not quitting work. We believe many people are making choices about what work they want in their lives. We discuss four reasons: 1) toxic workplaces 2) lifestyle and remote work 3) downstepping and 4) early retirement. We note that recruiters are toxic arms […]

On March 30th 2022, AWS announced automatic recovery of EC2 instances. Does that mean that AWS got feature-parity with VMware High Availability, or that VMware got it right from the very start? No and No.
Reading the AWS documentation (as opposed to the feature announcement) quickly reveals a caveat or two. The automatic recovery is performed if an instance becomes impaired because of an underlying hardware failure or a problem that requires AWS involvement to repair.

Frustrated by the limitations of Ethernet, Google has taken the best ideas from InfiniBand and Cray’s “Aries” interconnect and created a new distributed switching architecture called Aquila and a new GNet protocol stack that delivers the kind of consistent and low latency that the search engine giant has been seeking for decades. …

MPLS Multiprotocol Label Switching is one of the most popular and commonly used technologies in today’s Service Provider and Enterprise networks. In this post, we will explain the most fundamental topics about MPLS. After reading this post, you will learn a lot about MPLS, why we should use MPLS to MPLS packet formats, USA cases of MPLS to MPLS advantages and MPLS disadvantages, some recommendations about MPLS books, MPLS training, some basics MPLS questions, and many other things will be covered. Sit tight and let’s enjoy!.
Multiprotocol Label Switching – MPLS, is a networking technology that switch the network traffic using the shortest path based on “labels,” rather than IP destination addresses, to handle forwarding over a private Wide Area Network.
MPLS is a scalable and protocol-independent solution, that can carry Layer 3 IP and Non-IP and Layer 2 traffic, PPP, HDLC, Frame-Relay, Ethernet, all are possible.
MPLS provides transport and can be considered one of the tunneling mechanisms.
MPLS transport protocols as of 2022, are LDP, RSVP, Segment Routing and BGP LU.
An MPLS network is Layer 2.5, meaning it falls between Layer 2 (Data Link) and Layer 3 (Network) of the OSI Continue reading
For most enterprises, the future of IT is infrastructure and systems software that spans multiple clouds, a combination of both disparate public clouds and their own private clouds. …
