Automating Network Service Assurance — Is Device Telemetry Enough?
Brewing beer and network quality — what??
Juniper’s Stefan Vallin visited a brewery to answer a common question: Is device telemetry the single measurement tool needed to measure network quality? The answer, he says, is ‘no’ — and shows why by comparing it to craft beer brewing.
You’ll learn
How measuring network quality is similar to guaranteeing the quality of a craft beer
Why device telemetry cannot on its own effectively assess service quality
Why Paragon Active Assurance is the solution you need to monitor the health of your network
Who is this for?

00:01 stefan valen previously emphasized the
00:03 importance of measuring network quality
00:05 at the data plane very much the same way
00:07 you guarantee the quality of a craft
00:09 beer but we have received questions on
00:12 device telemetry is that not the single
00:14 measurement tool that's needed
00:16 okay i emphasize for active assurance
00:19 you should be measuring at the data
00:21 plane inject synthetic traffic so you
00:23 can measure loss latency etc directly
00:26 with the proper tools
00:28 you might ask yourself then what about
00:30 device telemetry isn't device telemetry
00:33 the way to go forward to measure the
00:36 service quality
00:37 well device telemetry is important but
00:40 it gives you the state of the devices it
00:42 doesn't really give you the health of
00:43 the network service let us compare that
00:45 with the brewery so in front of you here
00:48 you have the control panel of the
00:49 brewery
00:50 you see
00:51 measurements per capital so you can see
00:54 the temperature of each individual
00:56 kettle
00:57 sort of comparable with device telemetry
00:59 per device
01:01 but looking at
01:03 individual kettles the individual status
01:05 of each kettle
01:08 go from there to understand the bear
01:10 quality i would say is really impossible
01:13 we could try with a lot of data
01:15 analytics
01:16 to infer the health of the beer from
01:19 these individual kettles but that is
01:22 close to impossible
01:23 so that's the same thing with device
01:25 telemetry it tells you the health of the
01:27 device the kettle but it doesn't really
01:30 tell you the health of the network
01:32 service so measure the network service
01:34 directly by active assurance
