the IP topology, such as a NetworkConnection is LayeredOver a Circuit.
In the example shown in
Figure 1-3
, a
failure in the Optical network causes a failure in the ability to communicate
between two IP Routers. In order for
to perform analysis, it monitors events in OTM and IP domains
via remote instrumentation. In this case, OTM notifies TopologicalLink

receives these events and determines the true root cause. It
determines that TopologicalLink

causes the NetworkConnection

provides this to SAM. As a result, SAM shows the root cause as TopologicalLink
