Internet outage in Yemen amid airstrikes

The early hours of Friday, January 21, 2022, started in Yemen with a country-wide Internet outage. According to local and global news reports airstrikes are happening in the country and the outage is likely related, as there are reports that a telecommunications building in Al-Hudaydah where the FALCON undersea cable lands was hit.

Cloudflare Radar shows that Internet traffic dropped close to zero between 21:30 UTC (January 20, 2022) and by 22:00 UTC (01:00 in local time).

The outage affected the main state-owned ISP, Public Telecommunication Corporation (AS30873 in blue in the next chart), which represents almost all the Internet traffic in the country.

Looking at BGP (Border Gateway Protocol) updates from Yemen’s ASNs around the time of the outage, we see a clear spike at the same time the main ASN was affected ~21:55 UTC, January 20, 2022. These update messages are BGP signalling that Yemen’s main ASN was no longer routable, something similar to what we saw happening in The Gambia and Kazakhstan but for very different reasons.

So far, 2022 has started with a few significant Internet disruptions for different reasons:

1. An Internet outage in The Gambia because of a cable problem.
2. An Internet Continue reading

Video: Machine Learning Techniques

After Javier Antich walked us through the AI/ML hype and described the basics of machine learning it was time for a more thorough look at:

• Machine learning techniques, including unsupervised learning (clustering and anomaly detection), supervised learning (regression, classification and generation) and reinforced learning
• Machine learning implementations, including neural networks, deep neural networks and convolutional neural networks.

Edge computing in 2022: Double-digit growth

Worldwide spending on edge computing is expected to reach $176 billion in 2022, an increase of 14.8% over last year, according to new figures from analyst IDC.Edge computing started out rather modest in its use cases but has quickly expanded across industries and scope. Five years ago an edge network was a few mid-range servers in a ruggedized container. Now Nvidia and Lenovo are deploying GPU-based AI systems.How to choose an edge gateway “If we have learned anything over the last two years, the ability to quickly adapt to rapidly changing conditions is critical to business success. Organizations investing in edge computing combined with AI and modern application design will have an advantage when it comes to tackling whatever challenge comes next,” according to Dave McCarthy, research vice president for Cloud and Edge Infrastructure Services at IDC.To read this article in full, please click here

Cisco blends enterprise and industrial edge with new Catalyst switch

Cisco is expanding its Catalyst family of switches for enterprises that need to blend industrial and operational technology (OT) systemsThe the ruggedized Catalyst Industrial Ethernet 9300 1RU rack-mountable switch is based on the same programmable Unified Access Data Plane (UADP) ASIC found in other Catalyst 9000 and features 28 Gigabit Ethernet ports. Up to eight of the units can be stacked together and managed as one system.SD-WAN buyers guide: Key questions to ask vendors The 9300 runs the same IOS XE operating system as other Catalyst boxes and can be centrally  controlled via DNA Center, Cisco’s principal networking-control platform that features myriad services from analytics, network management, and automation capabilities to assurance setting, fabric provisioning, and policy-based segmentation.To read this article in full, please click here

Backing up a database depends on how it’s delivered

How you back up your database depends three factors: how the database is delivered to you, the backup logistics of the database, and the recovery time objective (RTO) and the recovery point objective (RPO) you are attempting to meet. This article covers how the database is delivered.There are three ways databases can be delivered: as software on a server you own; as platform-as-a-service (PaaS); and as a serverless service. Let’s take a look at them.[Get regularly scheduled insights by signing up for Network World newsletters.] Traditional database software Until a few years ago the way all databases were delivered was by buying a license for a product and installing it on a server or VM of your choice. You were responsible for everything, including the security and administration of the server, the storage, the application itself, and (of course) the backup of the database. To read this article in full, please click here

VMware Network Automation with NSX-T 3.2 and vRealize Automation

VMware Network Automation combines the modern microservices architecture of vRealize with VMware NSX network virtualization to enable rapid application rollout. The solution automates VMware NSX via VMware vRealize Automation to deliver complete workload lifecycle automation through networking, compute, and security services that make it simple to template, provision, and update complete environments. That, in turn, enables businesses to accelerate application delivery and drive overall agility.

The latest iterations of vRealize Automation native integration with NSX-T features include multiple new capabilities, such as support for NSX-T Federation, distributed firewall configurations from NSX-T, a shared gateway across on-demand networks, and many others.

In this post, we will provide an overview of the feature-set available with this native integration. The post doesn’t aim to be exhaustive, so don’t hesitate to look at the vRealize Automation documentation for more details.

Setting up the Environment

The native integration allows for consumption of NSX-T constructs from vRealize Automation after a simple configuration.

The goal is for the cloud admin to be able to offer users a self-service catalog, through Service Broker that enables the deployment of complex topologies with consistent governance policies across the cloud — all while abstracting the underlying infrastructure and its complexity from Continue reading
