The B_Tier table is used to define tiers, which are a collection of subnetworks that share the same level, name restriction, and topology type. Tiers are required for subnetwork management.


Target Domain Network

The network domain with which the tier is created in.

Tier Name

The tier name.


The rank of the tier being added. Ranking among tiers controls the order or hierarchy of the subnetworks. Valid inputs for this field are integers 1-n, with one being the highest level in the hierarchy.

Topology Type

The tier's topology type. The following are valid inputs:

  • MESH

Tier Group Name

The existing tier group for which the new tier will be added.

Subnetwork Field Name

The name of the field that the subnetwork name for this tier is stored in.

Support Disjoint Subnetwork

Defines if the tier supports disjointed subnetworks. Disjointed subnetwork are subnetworks that belong in the same tier, have the same subnetwork, but are not traversable. If supporting disjointed subnetworks, the field value is set to True.

Include Barrier Features

Defines whether the traversability barrier features are included in the trace results. Traversability barriers are optional even if they have been preset in the subnetwork definition. If including barriers, set the field value to True.

Apply Traversability To

The type of traversability to enforce. Traversability scope dictates whether traversability is enforced at junctions, edges, or both.

  • BOTH_JUNCTIONS_AND_EDGES - Apply traversability to both junctions and edges.
  • JUNCTIONS_ONLY - Apply traversability to only junctions.
  • EDGES_ONLY - Apply traversability to only edges.
