Abstract:
A network management system comprising a common object request broker architecture (CORBA) utilizing a push style of event service in which transmission of an event object from a server to a client is initiated by said server and is performed asynchronously via an event channel such that a plurality of servers may communicate with a plurality of clients asynchronously within the system without knowledge of each other;wherein said server includes transmission means for transmitting event data as required, and health check data at predetermined time intervals defined as health check send time intervals, wherein said client includes reception means for receiving health check data at said predetermined health check send time intervals to detect communication error based on failure to detect said receipt, where said server and client both have access to said health check data send time interval and a health check data transmission time-out period to enable both the server and the client to detect communication errors between said server and said client based thereon, and wherein an alarm is sent by an alarm means when a communication error is detected.
