System and method to aggregate control of multiple devices via multicast messages and automatic set up of connections

摘要

A method and apparatus are provided wherein the method includes the steps of a downstream controller of a security system advertising a service type of the downstream controller on a sub-network, a gateway controller of the security system detecting the advertisement and authenticating the downstream controller as being part of a group that also includes the gateway controller, the gateway controller sending a connection request to the downstream controller, the gateway and downstream controllers establishing an L4 connection based upon the connection request, and the gateway and downstream controllers establishing a L5 session channel through the L4 connection.

1. A method comprising:
a downstream controller of a security system advertising a service type of the downstream controller on a sub-network, the service type identifying at least a type of threat within a secured area of the security system due to fire; a gateway controller of the security system detecting the advertisement and authenticating the downstream controller as being part of a group that also includes the gateway controller; the gateway controller sending a connection request to the downstream controller; the gateway and downstream controllers establishing an L4 connection based upon the connection request; and the gateway and downstream controllers establishing an L5 session channel through the L4 connection.
