Controlling broadcasts in your network is one of your top priorities, so by using switches, that uses private collision domains with full-duplex and that allows us to transmit and receive at the same time. You now know we can create VLANs that break up the broadcast domain into smaller logical segments.
We must still be wary of broadcasts on our network, or each VLAN. If you place too many nodes on one VLAN, that segment could get overwhelmed, so you must constantly monitor you network/VLANs to make sure that traffic is still flowing efficiently.
One thing IT personnel overlook is protocols—every protocol creates some type of broadcast. It depends on three basic things:
- The type of protocol
- The application running on the network
- How the services are being used
So, it is not just creating VLANs and forgetting about it; we could be our own worst enemy...
