Industry groups prep Ethernet for operational, wireless networks

As Ethernet-based networks continue to evolve, two industry groups recently announced plans to take it to yet another level – this time extending the technology to operational and  wireless time-sensitive communication applications.This week the Ethernet Alliance said it was pushing an effort to bring faster, simpler communications to the operational technology (OT) networks typically found in building and industrial automation environments. The Ethernet Alliance includes a variety of communications players including Broadcom, Cisco, Dell, Juniper, Intel as well as university and industry members.[Get regularly scheduled insights by signing up for Network World newsletters.] A recently standardized IEEE specification, 802.3cg, which defines the use of Single-Pair Ethernet (SPE) in many circumstances rather than a wide range of fieldbus cables, including RS‑485 twisted-pair, RG‑6 coaxial, and instrumentation cables is behind the group’s strategy. To read this article in full, please click here

The 2020 Indigenous Connectivity Summit and Trainings: Register Now

People around the world are relying on the Internet to keep them connected to everyday life, but Indigenous communities in North America are being left behind by companies and governments. Lack of connectivity means many are unable to access even basic information and healthcare. And while COVID-19 has hit Indigenous communities especially hard, lack of access means they can’t use services that connected populations consider critical, such as remote learning and teleworking.

We must address this critical gap.

For years, the Internet Society has worked with those very communities, along with network operators, technologists, civil society, academia, and policymakers – bringing them together to discuss what can be done collectively to narrow the digital divide. We do this through our Indigenous Connectivity Summit (ICS) and the pre-Summit Trainings: Community Networks and Policy and Advocacy.

This year, though we can’t meet in person, we’ll hold a virtual event.

We’re excited to announce that registration is now open for the 2020 Indigenous Connectivity Summit.

The Summit will take place October 5-9, 2020, with training sessions beginning the first week of September. Those who register for the Summit before Friday, September 11th will receive a swag bag and materials for hands-on training prior to the Summit. Continue reading

Accelerating the data center with NVIDIA, Mellanox + Cumulus

Today’s modern datacenter and cloud architectures are horizontally scalable disaggregated distributed systems. Distributed systems have many individual components that work together independently creating a powerful cohesive solution. Just like how compute is the brains behind a datacenter’s distributed system, the network is the nervous system, responsible for ensuring communication gets to all the individual components. This blog tells you why NVIDIA Mellanox gives NVIDIA a larger footprint in the datacenter. The combination of NVIDIA, Mellanox and Cumulus together can provide end-to-end acceleration technologies for the modern disaggregated data-center.

Accelerating the datacenter

All parties coming together in this acquisition are involved in acceleration technologies in the modern data center:

• NVIDIA is at the center of Compute acceleration: Its GPU’s provide compute acceleration for High performance computing and infrastructure for neural networks that power AI assisted application features.
• Mellanox comes to the table with its dominance in High performance interconnects, Data and network processing acceleration on the host and hardware for the network fabric
• Cumulus Networks provides the Linux stack to accelerate the network fabric by enabling networking hardware features, and accelerating deployment, integration and monitoring of the network fabric with Automation and the Linux ecosystem. Cumulus Networks software architecture and DNA Continue reading

NTC – Netpalm With Tony Nealon

Open source continues to accelerate in the network domain with projects such as Netmiko, NAPALM, and Nornir–all of which are led by individuals, not large organizations or venture-backed startups.  In this episode we sit down with Tony Nealon, creator of Netpalm. Netpalm is a network API platform that can abstract and render structured data, both inbound and outbound, to your network device’s native telnet, SSH, NETCONF or RESTCONF interface–leveraging popular libraries like NAPALM, Netmiko, and ncclient under the hood for network device communication

How to Simplify and Accelerate Network Segmentation 

Network segmentation—splitting a network into subnetworks or segments—is widely accepted to be a powerful and effective method for improving cybersecurity within the data center. Yet even though it’s acknowledged to be an essential component of network security hygiene, organizations have frequently avoided putting segmentation into practice.  

Why? Because historically network segmentation has been complex, disruptive, and time-consuming to implement, requiring extensive changes to the physical network and/or network addresses. The potential impact of taking applications offline for network changes means that many organizations decide to forego this industry-wide best practice. Teams that do forge ahead often face months- or years-long effort to create security zones by re–architecting the network, relocating equipment, and re-assigning IP addresses.  

It doesn’t have to be that way. Today there’s an elegant solution that greatly simplifies and accelerates network segmentation: VMware NSX Service-defined Firewall. Purpose–built to protect east-west traffic, VMware Service-defined Firewall enables segmentation without any disruptive physical network or address changes. 

Attackers Love Flat Networks  

To back up a step, let’s examine why network segmentation  Continue reading

Worth Reading: Seamless Suffering

When someone sent me a presentation on seamless MPLS a long while ago my head (almost) exploded just by looking at the diagrams… or in the immortal words of @amyengineer:

“If it requires a very solid CCIE on an obscure protocol mix at 4am, it is a bad design” - Peter Welcher, genius crafter of networks, granter of sage advice.

Turns out I was not that far off… Dmytro Shypovalov documented the underlying complexity and a few things that can go wrong in Seamless Suffering.

Jinja Template Inheritance

Jinja template inheritance uses the concept of block to define sections of the base parent template that can be overridden by sections from a child template. An extends statement links the child template to the parent template so that when the child template is rendered the parent template is also rendered and the block statement contents inherited by the parent template.

There is enterprise-level software for surveying Wi-Fi networks, but even in large wireless networks, simple freeware tools are handy for a quick peek at the airwaves during design, deployment or troubleshooting.Here is a look at eight free tools – some for Windows and some for Mac OS X – that provide basic details about nearby Wi-Fi signals: SSIDs, signal strength, channels, MAC addresses and security status. Learn about 5G and Wi-Fi 6 What is 5G? How is it better than 4G? How to determine if WiFi 6 is right for you What is MU-MIMO? Why do you need it in your wireless routers? When to use 5G, when to use WiFi 6 How enterprises can prep for 5G networks Some can even reveal “hidden” or non-broadcasted SSIDs, display the noise levels, or display statistics on successful and failed packets of your wireless connection. One of them includes Wi-Fi password-cracking tools that are useful for educational or penetration testing purposes.To read this article in full, please click here

Deploying WordPress to the Cloud

I was curious the other day how hard it would be to actually set up my own blog or rather I was more interested in how easy it is now to do this with containers. There are plenty of platforms that host blogs for you but is it really now as easy to just run one yourself?

In order to get started, you can sign up for a Docker ID, or use your existing Docker ID to download the latest version of Docker Desktop Edge which includes the new Compose on ECS experience. 

Start with the local experience

To start I setup a local WordPress instance on my machine, grabbing a Compose file example from the awesome-compose repo.

Initially I had a go at running this locally on with Docker Compose:

$ docker-compose up -d

Then I can get the list of running containers:

$ docker-compose ps
           Name                          Command               State          Ports
--------------------------------------------------------------------------------------
deploywptocloud_db_1          docker-entrypoint.sh --def ...   Up      3306/tcp, 33060/tcp
deploywptocloud_wordpress_1   docker-entrypoint.sh apach ...   Up      0.0.0.0:80->80/tcp

And then lastly I had a look to see that this was running correctly:

Deploy to the Cloud

Great! Now I needed to look at the contents of the Compose file Continue reading

Partnering with Euro-IX on Infrastructure Development, Routing Security, and More

We can only be successful in creating an Internet for everyone if everyone is part of the effort. That’s why the Internet Society is thrilled to be entering into a partnership with the European Internet Exchange Association (Euro-IX).

The partnership was made official with a Memorandum of Understanding (MoU) on 14 July. This formal agreement builds on an existing collaboration between the two organizations, who have worked together since 2012. But, whether it’s helping to bring cheaper and faster Internet to the world through the data provided in the IXP Database or making the Internet more secure by supporting the Mutually Agreed Norms for Routing Security (MANRS), our work has only just begun.

Kjetil Otter Olsen, the chair of Euro-IX said, “The Internet Society has been an excellent supporter of Internet exchange points (IXPs) for many years and has lent the support of its teams across the world to promoting the benefits of peering for Internet networks and the end users of those networks globally.

“Signing this MoU, on behalf of Euro-IX and the community of IXPs we represent, reflects our shared commitment with the Internet Society to continue this work into the future.

“This MoU extends our existing relationship Continue reading
