Wireless SLEs

SUMMARY Get started using Service Level Expectations (SLEs) to visualize the data for your wireless network.

Wireless SLEs Video Overview

Watch this short video to get a quick overview of Wireless SLEs.

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?

Service-level experiences (SLEs) help you understand a user's wireless network experience. Juniper APs collect key data of every user's wireless experience and normalizes the data to a user minute metric, which is then rolled up in the Juniper Mist cloud, which applies machine learning to create useful information. From the dashboard, you can visualize the data for the entire organization, individual sites, or even individual clients. For more information, see the Wireless SLEs chapter of this guide.
