There’s a 3-6 month wait for Wi-Fi 6

Wi-Fi 6 is the most sought-after wireless LAN technology by enterprises, but the global chip shortage is preventing it from getting into the hands of IT pros as quickly as desired, according to the Dell’Oro Group.The usual amount of lead time required for a purchase of new Wi-Fi equipment is two to four weeks, according to the report’s author, Tam Dell’Oro, the CEO and founder of the group. “Now, we’re looking at between three and six months,” she said.[Get regularly scheduled insights by signing up for Network World newsletters.] The worldwide dearth of silicon is to blame. According to Dell’Oro, the biggest enterprise Wi-Fi vendors were the first to feel the pinc eharlier this year. Cisco, Extreme, and HPE/Aruba reported in their second-quarter results that the shortage was affecting supply, and many more US and European sellers reported similar problems in the third quarter.To read this article in full, please click here

Review of two Cradlepoint mobile routers

At the transportation organization where I work, we employ two Cradlepoint mobile-router models in our vehicles: the industrial IBR-1700 vehicular routers in our 97 buses and eight smaller IBR-900 vehicular routers in maintenance trucks, operations vans, and other multipurpose vans.The reason for these cellular routers in the buses is to provide a WAN connection to systems on the buses including GPS, electronic signage, passenger counters, and fareboxes.How they are networked These information-gathering systems connect to the primary processing device on the vehicles called the medius box, which is part of our computer-aided dispatch/automatic vehicle location (CAD/AVL) setup. The medius boxes are connected to the Cradlepoint routers, which link over 4G LTE to a server that collects and manages all of the vehicle’s location and onboard media data.To read this article in full, please click here

Calico WireGuard support with Azure CNI

Last June, Tigera announced a first for Kubernetes: supporting open-source WireGuard for encrypting data in transit within your cluster. We never like to sit still, so we have been working hard on some exciting new features for this technology, the first of which is support for WireGuard on AKS using the Azure CNI.

First a short recap about what WireGuard is, and how we use it in Calico.

What is WireGuard?

WireGuard is a VPN technology available in the Linux kernel since version 5.6 and is positioned as an alternative to IPsec and OpenVPN. It aims to be faster, simpler, leaner and more useful. This is manifested in WireGuard taking an opinionated stance on the configurability of supported ciphers and algorithms to reduce the attack surface and auditability of the technology. It is simple to configure with standard Linux networking commands, and it is only approximately 4,000 lines of code, making it easy to read, understand, and audit.

While WireGuard is a VPN technology and is typically thought of as client/server, it can be configured and used equally effectively in a peer-to-peer mesh architecture, which is how we designed our solution at Tigera to work in Kubernetes. Using Calico, Continue reading

Hedge 110: Andrew Alston and SRv6 Security

SRv6, a form of source routing, is the new and interesting method being created by the IETF to allow traffic engineering and traffic steering. This is not the first time the networking world has tried source routing, however—and in the spirit of rule 11, we should ask some questions. How and why did source routing fail last time? Have we learned those lessons and changed the way we’re doing things to overcome those limitations? Security seems to be one area where problems arise in the source routing paradigm.

Andrew Alston joins Tom Ammon and Russ White to discuss security in SRv6.

Introducing Red Hat Ansible Automation Platform 2.1

We are thrilled to announce the general availability of Red Hat Ansible Automation Platform 2.1. This is the follow-on to the Ansible Automation Platform 2.0 Early Access released this summer, and announced at AnsibleFest 2021. Red Ansible Automation Platform 2.1 introduces major features that allow customers to onboard more easily with even more flexible automation architectures and use cases. Ansible Automation Platform 2.1 is the culmination of many years of reimagining how enterprise automators automate for today and tomorrow.

You can download the latest version directly from the Red Hat Customer Portal, or sign up for a free trial at red.ht/try_ansible. Ansible Automation Platform is the Ansible you know and love, designed for the enterprise. I am going to summarize Andrius Benokraitis’ blog post from September, when Ansible Automation Platform 2 was announced, and expand on some key developments from 2.0 to 2.1.

First, some general information:

  • The Ansible Automation Platform life cycle page has been updated.

  • Moving forward, every Ansible Automation Platform minor release will now have its own unique Red Hat Subscription Management repo, which requires an Ansible Automation Platform subscription.

Confluent Platform 7.0: Data Streaming Across Multiclouds

The challenge is clear: How to offer real- or near real-time access to data that is continually refreshed across a number of different distributed environments. With different types of data streaming from various sources such as multicloud and on-premises environments, the data, often in shared digital layers such as so-called digital information hubs (DIHs), must be updated asynchronously. This is necessary in order to maintain a consistent user experience. To that end, data streaming platform provider Apache Kafka, hundreds of different applications and data systems can use it to migrate to the cloud or share data between their data center and the public cloud, Confluent says. Traditionally, syncing data between multiple clouds or between on-premises and the cloud was “like a bad game of telephone,”

LoRa takes a trip to the moon and back, chirping all the way

LoRa is living up to its name, literally.A shortened version of “long range” (ironic!), LoRa is a wide-area wireless modulation technique that encodes information on radio waves. LoRa, which has been around since 2015, is derived from Chirp Spread Spectrum (CSS) technology and uses chirp pulses to transmit small bits of data. It also uses very little power. The proprietary technology is owned by semiconductor supplier Semtech Corp[Get regularly scheduled insights by signing up for Network World newsletters.] LoRa’s value is in transmitting data for sensors and other connected devices that require little power to operate. Not only can LoRa withstand disturbances, it can transmit data at longer ranges than better known wireless technologies such as Wi-Fi and Bluetooth. So long, in fact, that demonstrations of LoRa’s transmission capabilities now must extend into near space.To read this article in full, please click here

Optimal BGP Path Selection with BGP Additional Paths

A month ago I explained how using a BGP route reflector in a large-enough non-symmetrical network could result in suboptimal routing (or loss of path diversity or multipathing). I also promised to explain how Advertisement of Multiple Paths in BGP functionality1 solves that problem. Here we go…

I extended the original lab with another router to get a scenario where one route reflector (RR) client should use equal-cost paths to an external destination while another RR client should select a best path that is different from what the route reflector would select.
