So let's dive into it. Our core functionality for the network management platform is around user service level expectations. So every user, every minute we collect the data to answer the simple question, are users able to connect and are they having a good experience? So what you see here is the site level, this is our global headquarters here in Sunnyvale, the entire site's wireless experience.

So we could take this one level up and essentially show you where all the sites around the world from their service level expectations are doing. And you could take this one step further on understanding the successful connect experience and see which sites are having certain issues. You can understand coverage, roaming.

We've introduced some really cool roaming metrics this year around signal quality and stability of roams, all this kind of stuff. This is on the wireless side. This is the org level service level expectation view that we talk about.

Now, the next core function for our platform is around understanding the experience and taking it down and saying, who all are impacted? And once you know which devices are impacted, being able to go into an individual device. Here, I've zoomed in to a specific device and that specific device, we're showing you now service levels for that individual device. Every device, every minute, we have the data and being able to zoom in to a certain time and say,why was that device not having a good experience? Aha, it's DNS failure.

The device wasn't having good roaming experience. Aha, it's signal quality. Every user, every minute, service levels.

Then you can go in and say, okay, I want to understand this particular device and go into that individual device's experience and see what are the specific signals? What are the specific failures we see for this device? And there's lots and lots of DNS failure for this particular device. Being able to get to that kind of level and specificity of detail with just a couple of clicks, that's the power of the MIST dashboard at a operations level, at a configuration level as well.

What Do You Want to Do?

Mist service level expectations (SLEs) help you understand a user's wireless network experience. Juniper APs collect key data about every user's wireless experience, upload it to the cloud, then the Juniper Mist portal normalizes the data to a user minute metric. Then the Juniper Mist portal applies machine learning to create measurable and actionable information about successful connections, time to connect, wireless throughput and more. From the various Mist dashboards, you can visualizethis information across the entire organization, individual sites, or even individual clients.

You can view SLEs specific to Wireless client experience in the Juniper Mist dashboard by selecting Monitor> Service Levels from the main menu. Juniper Mist tracks seven SLEs for Wireless client experience. A summary of each follows.

Time to Connect SLE—Shows the percentage of successful connections (initial, roaming, and ongoing) compared to the set threshold.
Wireless Successful Connects SLE—Shows the percentage of connections (initial, roaming, and ongoing) that completed successfully.
Wireless Coverage SLE—Shows the percentage of the time that the signal strength received from wireless clients exceeded the set threshold.
Roaming SLE—Shows the percentage of successful roams compared to the set threshold.
Wireless Throughput SLE—Shows the percentage of the time that the throughput available to the wireless clients was greater than the set threshold.
Wireless Capacity SLE—Shows the percentage of the time that the capacity of the available radio frequency channel exceeded the set threshold.
AP Health SLE—Shows the percentage of the time the APs have been operational without losing connectivity to the cloud or rebooting. It also includes the sub-classifiers, Latency, Jitter, and Tunnel.
