Carrier-grade SNMP interface for fault monitoring
A method, system and apparatus enables carrier-grade network fault monitoring in an unreliable network transport environment. An element manager of the system is adapted for formulating and sending notifications through the unreliable network transport environment, each notification having an unique transmitted notification serial number (TxNSN). A network manager is operatively connected for bi-directional communication with the element manager. The network manager includes a detection mechanism responsive to notifications received from the element manager to detect a missing notification on the basis of the respective TxNSNs of received notifications; and a polling mechanism responsive to detection of a missing notification to send a polling request to the element manager for transmission of a response containing data related to the missing notification. The advantage is simple, easily managed, carrier-grade network fault monitoring without overloading the unreliable network transport environment.
