CTS 341: Meter Command – Dynamic and Adaptive Network Management (Sponsored)
Aug 21, 2024
https://youtu.be/8u0hXi-tMIk
Meter is going one step beyond AI chat bots with their product Command. It’s a generative UI that goes beyond command line interface and adds visuals to create custom dashboards using a natural language interaction.
A network operator can make queries for their network, configure SSIDs, new networks, and other network changes by using plain English.
Meter Command allows a network operator to be highly efficient and productive. A simple English query can yield results of the network. Or if you need to build a custom dashboard for a CTO, you can ask Meter Command to build that for you. No extra coding experience required.
Another great aspect of Meter Command is it is built to be collaborative with other team members. Troubleshooting can be kept in a single canvas and updated dynamically. Dashboards can be created and modified on the fly by collaborating with other team members.
Wi-Fi 7 is just around the corner. It offers new features and complexities to help increase throughput and maintain low latency. In this episode, we’re joined by Arista Networks who gives us a run down on the different versions of MLO.
With their testing, they’ve seen a few versions of MLO being used. As well as seeing when MLO gets triggered and how much throughput you can acquire when connecting to the same AP on different bands.
For stability, Arista Networks displays how preamble puncturing works when interference is detected in a wide channel. The specific channel seeing the interference is removed from the channel width without affecting the other channels.
CTS 339: Cisco Meraki Brings New Functionality at MFD11
Jul 01, 2024
https://youtu.be/z-goZs5Z7aY
Meraki starts with telling us the Wi-Fi trifecta of readiness. That is Regulatory/specs/certifications, Clients, and Infrastructure. You need all of this.
And when you have all of this in place, Meraki adds useful features for the network operator.
Features such as Proactive PCAP and Root Cause Analysis. This isn’t just a PCAP file you download. Meraki goes further to tell you what is wrong within the PCAP and what potential solution can resolve the issue.
We’re seeing what the APs are capable of and how the dashboard can help resolve today’s network issues.
Fortinet has had a strong portfolio. They’ve been able to show all the solutions that are pertinent to a secure Wi-Fi network at every Mobility Field Day they’ve attended. This one is no different.
Their end-to-end solutions make it easy for any organization to select Fortinet.
It’s no shock that they’ve been able to develop a Wi-Fi 7 access point. But now they’re diving into Firewall as a Service while still providing the flexibility for any organization to migrate between the management method needed to grow and expand as required.
CTS 337: Live Heatmap Views at Your Fingertips (Sponsored)
Jun 10, 2024
https://youtu.be/I6KASVEiCag
Rowell and Jussi discussed the integration and functionality of a new live view feature in Hamina. Jussi explained that the feature pulls data from the vendor, including details such as AP locations, maps, transmit powers, and more, to create a more accurate network coverage prediction. The discussion also touched on the system’s ability to account for environmental factors like wall attenuation, with Jussi noting that the system’s accuracy in this area will likely improve over time. Rowell expressed interest in understanding more about how the floor plan is incorporated into the vendor data.
Also discussed was the potential of using AP data to create detailed floor plans and site maps, which could be used for live troubleshooting and capacity planning. Exploring the possibility of pulling in client data into these heat maps to provide a more comprehensive view of the network. In the recording, Rowel and Jussi touched on the potential of integrating data from different vendors to create a more complete picture. However, that the ability to do so is dependent on what the vendors choose to provide via their APIs.
CTS 336: Network as a Service with Meter (Sponsored)
Jun 03, 2024
In this episode, we’re speaking with Anil Varanasi – the CEO at Meter. He’s an engineer that set out to solve an infrastructure problem with his brother, Sunil.
Meter, founded in 2015, is a Network as a Service company that provides end-to-end networking solutions. From firewalls, to switches, and Wi-Fi – they provide the infrastructure for businesses so they can do what they do best.
Their purpose is to build great beautiful networking that combines products and services into a single solution.
Meter has also developed an in-house solution to help network admins procure ISP services for their offices – making it even easier to get up and running fast.
Meter scales to provide a single pane of glass for management of multiple sites. It’s simple to add firewalls, switches, and access points.
Anil provides his insight into how they position themselves in the industry and how they can help network admins with their day-to-day job.
And you might think, a Network-as-a-Service might not give you the granular configuration management or insight, but that is further from the truth. It’s built for network engineers with various knobs available for fine tuning.
Check out Meter and the resources below to learn more.
Live demos are awesome to see. And when executed very well it is impressive. Arista Networks came to Mobility Field Day 11 ready to wow the delegates.
With a Wi-Fi 7 access point in the room and a Google Pixel phone, they were able to show how MLO works in Wi-Fi 7.
From their dashboard, it showed how the phone was associated to both 5 GHz and 6 GHz channel on a single access point.
In addition to MLO, they also showed a demo of how puncturing would work. An interference source was synthetically created via software just to show one channel being removed but Wi-Fi still operating well.
Check out the MFD11 video and be sure to look at the pcap Rowell was able to capture which shows the MLO information elements.
CTS 334: Juniper Networks Announces New Features at MFD11
May 27, 2024
https://youtu.be/nCLoqCq-1CM
Rowell was fortunate to be a delegate for Mobility Field Day (MFD) 11 which was located in Santa Clara, CA. Juniper Networks was the first presenter at MFD11 and just like in previous MFD events, there were many announcements and new features coming to the Mist dashboard.
A lot of the discussion does revolve around Marvis and the AI capability. Marvis Minis weren’t announce too long ago for access points and now they will be extended to providing testing for applications such as Zoom and Teams. With this comes new Application SLEs.
Providing insight into the user experience is a nice way to measure the impact of poor application performance. AI is used to take Zoom data merged with network data from wired, wireless, SD-WAN, etc to build models that can predict latency with up to +/- 9ms of accuracy.
When it comes to user experience, I would like to gather data closer to the device being used. That’s where the Marvis Client Agent comes into play. It will be able to provide more information to feed on layer 2 information and display within Client Insights on the dashboard.
Troubleshooting Wi-Fi is challenging. But the Mist dashboard is helping to bridge the gap by providing information that occurred in the past with Dynamic Spectrum Capture. We’ve known that intermittent issues have been difficult to track, especially RF interference.
And when you have to troubleshoot remote sites, it’s not easy to fly someone onsite to troubleshoot, especially when travel costs are involved. Juniper Networks brought Jussi Kiviniemi as a guest to display live troubleshooting and analysis using Hamina. It utilizes the Mist API to pull in RF data to get a live heatmap view on a floor plan within Hamina.
Like I said, Juniper Networks announced a lot of new features. Watch the full video for yourself!
CTS 333: Understanding Wi-Fi Channels and Frequencies
