ECIM-R defined relationships enable the IP Manager to associate the discovered network systems with each other, with their internal components, and with their connections. Because the relationships establish dependencies between the discovered objects, the IP Manager is able to correlate alarms from the managed objects to pinpoint the failed object, or root-cause problem, and to identify all managed objects that are affected by the failed object.

Network object relationships describes some of the relationships that can appear in the ECIM-R representation of IP network topology.

1 Does not have an inverse relationship.

The examples given here are just a few of the many relationships that can appear in the ECIM-R representation of IP network topology. Generally, as demonstrated in the examples, for every relationship, there is an inverse relationship. For example, PartOf is the reverse relationship of ComposedOf.
