This section describes the fault management architecture.
Polling management data
The MAS supports the polled management model of the Simple Network
Management Protocol (SNMP) to facilitate well-controlled network
management traffic and to enable reliable data synchronization through a
request-response interaction. By maintaining Management Information Base
(MIB) tables and variables, the Internet Protocol (IP) Multimedia System (IMS)
enables the following functions:
•
To recover the missing data due to lost notifications. This is referred to as
auditing and is described in the next section.
•
To perform initial data synchronization for the active alarm list.
•
To monitor the status of operation, administration, and maintenance
(OAM) communications with the agents and resynchronize all data after
recovering from communication loss.
