0:04 hi let's dive into a hot topic for
0:06 service providers today delivering low
0:09 latency connectivity services and slas
0:12 wouldn't it be great if you could
0:14 monitor endtoend measured latency
0:17 continuously and in real time better yet
0:21 how about rerouting low latency traffic
0:23 around problematic links in real time
0:26 and completely autonomously it's
0:29 possible to today with low latency
0:31 routing a juniper Paragon use case we
0:34 combined an advanced path computation
0:37 capability with real-time Telemetry and
0:40 active testing on the data plane you get
0:43 a fully autonomous real-time latency
0:46 based routing capability that eliminates
0:48 manual investigation accelerates issue
0:51 resolution and ultimately delivers a
0:54 differentiated more resilient and more
0:57 performant service to your high value
1:00 customers now let's see how it works we
1:03 can see our transport Network which is
1:05 supporting a mesh of low latency tunnels
1:08 and we're looking at the measured delay
1:10 kpi for each link that's measured via
1:12 twamp this link right here is by far the
1:15 lowest latency in the network that's why
1:18 our low latency tunnels are passing
1:20 through it because end to end it's how
1:23 they get from point A to point B with
1:25 the minimum possible
1:28 latency but what happens if the latency
1:31 on that link suddenly increases are
1:33 those low latency tunnels still on the
1:35 lowest latency path if not what is the
1:39 new optimal path let's see how Juniper
1:42 Paragon handles
1:44 this on the left we're seeing realtime
1:46 data plane latency over time for tunnels
1:49 using that low latency link on the right
1:52 we're seeing latency per link as
1:54 reported by the routers themselves
1:57 here's our low latency link again see
2:00 that something's causing a rapid
2:02 increase in latency it's now about 100
2:06 times higher at 20 milliseconds and it's
2:09 reflected on the data Plane 2 Juniper
2:12 Paragon is already analyzing the
2:13 situation and identifying what tunnels
2:16 to reroute and where let's back up a few
2:19 seconds and see this in action we had
2:22 seven tunnels relying on that link
2:24 before and now those tunnels are
2:27 avoiding that link in just a few seconds
2:30 Juniper Paragon has detected analyzed
2:33 and automatically reallocated them to
2:36 use the new shortest path no human
2:39 intervention
2:40 required we can confirm by looking at
2:43 the data plane delay kpi again and
2:46 indeed those end to-end tunnels have
2:48 successfully avoided more than a few
2:50 seconds of high latency what might have
2:53 taken hours to fix with traditional
2:55 tools we've just done in seconds no
2:59 human intervention required that's all
3:01 it takes deliver differentiated services
3:05 and SLA guarantees with latency based
3:08 routing a juniper Paragon automation use
3:17 case
