Broadcast Domain Isolation

Definition

Broadcast isolation restricts the number of computers a host can contact on their LAN.

Synonyms: Network Segmentation .

How it works

Software Defined Networking, or other network encapsulation technologies intercept host broadcast traffic then route it to a specified destination per a configured policy.

This can be implemented within hypervisors, networking hardware (WAPs, switches, routers), or virutal hardware.

Considerations

This technique is highly dependent on network infrastructure and networking requirements.
