ABSTRACT:
A modified form of the UDP multicast protocol is disclosed to implement a one-way notification method between a server and one or more clients. The UDP multicast notification method enables UDP messages to be sent only to registered clients, not broadcasted to all clients. This architecture minimizes network traffic and enhances system security, since only registered clients receive the UDP message. The configuration of the UDP multicast notification method does not require the configuration of network devices in order to support a UDP multicast. Furthermore, any number of the clients may be on a different network domain than the DCM engine.
