Topology Manager
The Topology Manager provides topology information of the control domain. It also facilitates
shortest path traversals through the control domain by computing low cost next-hops or link edge
weight between any two datapaths in the control domain. Topology Manager creates the clusters
and broadcast tree to avoid loops and broadcast storms. The Topology Manager:
• Indicates whether a connection point is part of Infrastructure or is connected to an end host
• Indicates whether ingress broadcast traffic can be allowed through a specified connection
point
