Automated WAN—Congestion Avoidance

0:02 [Music]

0:04 hi I'm going to show you a quick

0:06 demonstration of congestion avoidance a

0:09 juniper Paragon use case with congestion

0:12 avoidance you can deliver guaranteed

0:15 slas unlocking new Enterprise revenue

0:17 streams in the process reduce human

0:20 error by automating Common manual tasks

0:23 and prevent customer impacting issues by

0:26 resolving root causes before the

0:29 customer notices the problem so let's

0:31 dive into it starting with active LSP

0:35 monitoring we're measuring congestion

0:37 through Telemetry data and at a glance

0:40 we can see one particular link running

0:42 hot over 80% utilization here we see

0:46 three tunnels passing through the

0:48 heavily utilized link to deal with this

0:51 all we have to do is set a utilization

0:53 threshold and Juniper Paragon takes care

0:55 of the rest as soon as the moving

0:57 average utilization crosses that

0:59 threshold old for any router in the

1:01 network Juniper Paragon will recalculate

1:04 all paths and tunnels effectively

1:06 redistributing the load throughout the

1:08 network so that no single link is

1:10 running too hot and without impacting on

1:13 customer experience this is where

1:16 automated rerouting comes in within just

1:19 a few seconds of setting the threshold

1:21 Juniper Paragon recalculates and re

1:24 optimizes the tunnels running through

1:26 the network to fulfill the intent of

1:29 reducing U ization below the threshold

1:32 for all links we can see it happening

1:34 from the colorcoded dashboard the tunnel

1:37 is now passing through a different

1:38 router Distributing the traffic such

1:41 that now no interface throughout our

1:44 network has utilization above the

1:46 threshold we set run your network hotter
