October 2012 - "Network Types" is the third video in our Understanding BACnet Series. The series is an overview intended for those who are encountering BACnet for the first time or those who simply wish to review basic BACnet concepts.
BACnet is a communications protocol for Building Automation and Control Networks. One of its primary appeals is that it provides "interoperability" among different vendor's equipment. This frees the building owner from dependence on one vendor when the time comes for system expansion.
"Network Types" covers the BACnet collapsed four-layer version of the seven-layer Open Systems Interconnect model and examines how BACnet is implemented in the Application, Network, Data Link and Physical layers.
