The QoE tab provides a crucial view of all the links at a site. You can see how the network’s performing, using a graphical representation of each link right alongside the aggregate link. This video will walk you through the QoE tab, and help you configure and control it to make managing your network fast and straight forward.
In this short video we’re going to look at the Q o E tab on the orchestrator. This is the quality of experience screen, it’s mostly informational. But it’s one of the tools we can use to diagnose faults and site performance issues. This page shows the overall status and quality of the induvial access links for a given site, it’s in real time and you can choose the time frame you want to see. Here’s what the colours mean. Green means good, orange is fair, red is critical and white means the link is unavailable. It also shows any remediation that the edge box is doing to resolve issues on a specific link. In this case, by hovering over the link you can see that the 4G service has had a few jitter problems throughout the day. It’s useful to know that you can change the time frame you’re looking at by dropping down this box, so you might like to see a high level overview of the last 7 days, or come down to a granular level, and look at the last 60 minutes. You can even take a look at extended periods, like 6 months or a year, let’s have a look at this site’s links over the past 7 days. Macquarie Telecom SD-WAN automatically gives each link a quality score out of 10, the score is based on uptime, latency, jitter and packet loss. It’s a real time measure. The aggregated link also has a quality score.
In this example you can see the two links have reasonable quality scores but they aren’t really that close to 10. When we have a look at the quality score for the aggregated data link we can see it’s very close to 10. In our current view this quality score is derived from the traffic type of voice. Voice traffic has more stringent requirements of packet loss, jitter and latency, in order to deliver a good user experience. To achieve a high score, the network has to be performing exceptionally well.
This dropdown lets you choose from various traffic types, to ensure a meaningful quality score. In addition to voice, you can also select video, which has similar metrics to voice. Or transactional, which means basic file transfers. Jitter doesn’t matter so much, but packet loss is still important. This screen defaults to voice which is the most stringent. When we change the traffic type, you can see the scores and graphics also change, to reflect the criteria.
Last, in addition to the time scale, you can also choose a specific period of time to look at. So for example you might choose the 13th September at 10am, through to the 14th September at 6am. You can then see the performance metrics that would have been visible at that time.
Thanks for taking a look at this video about the Q O E tab in the orchestrator. You can find some more videos about SD-WAN on our website. Bye for now.
