Abstract
A network management system utilizing the push style in which transmission of an event from a server to a client is performed asynchronously via an event channel. The server includes a transmitter for transmitting data at a predetermined time interval, for detecting any communication errors between the server and the client. Thus, the requested client can detect errors such as a disconnection between the client and the server and a recording medium on which a network management program is recorded.
Claims9
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.
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;
- wherein said client includes means for periodically receiving health check data for executing a health check to determine communication errors, if any, between server and client, and reception means for receiving said transmitted health check data via said event object detection means for detecting whether or not, after receiving said health check data, either health check data to be sent subsequently to said health check data or said event has not been received within a predefined health check data transmission time out period, and means for sending an alarm when said detection means detects that neither said health check data to be sent subsequently nor said event has been received within said predefined health check data transmission time out period.

- wherein said server includes transmission means for transmitting health check data at a predetermined health check data send time interval, for detecting communication errors between said server and said client;
- said client includes means for receiving health check data for executing a health check, and reception means for receiving said health check data, detection means for detecting whether, after receiving said health check data, either health check data to be sent subsequently to said health check data or said event has been received or not within a predefined health check data transmission time out period, and means for sending an alarm when said detection means detects that neither said health check data to be sent subsequently nor said event has been received within said predefined health check data transmission time out period.
