Topology Metadata

Topology Information

The most precious of metadata

A single PM session only tells you if there was a problem between two points, but using PM on a massive scale while overlaying topology data can start to reveal insights about specific network elements without measuring them directly

Physical vs Logical Topology

• We treat Topology as a comma separated string of elements - you decide if that's used for physcial or logical path use cases
• A logical topology can define: the conceptual path of a session, application transaction paths or any logical flow that you want to define based on business definitions
• I.e., topology doesn’t have to be a set of routers… the hops can be conceptual like an MPLS circuit, Server-client relationship etc.

Uploading Topology Metadata

How do we define the Topology Metadata?
To support correlation of element performance across all network session topology, irrespective of the position of the element in the path, we define a topology as an ARRAY:

• {hop1, hop2, …}

This data is updatable via our REST APIs or through the UI.
