Network fault management strategy

The system handles network fault management through the reporting

of alarms and logs. RTP Media Portal alarms and logs are viewed from

the System Management Console. (See the MCP System

Management Console Basics for further details related to alarms and

logs.)

Fault tolerance

The RTP Media Portal provides base capabilities that significantly

improve the performance and reliability of the system in the event of a

fault. These capabilities include:

• Dynamic Pool Registration

— provides the basic mechanism that ensures resource availability

and utilization in the event of a SIP Application Module failure.

This function works in tandem with SIP Application Module

redundancy to ensure that RTP Media Portal resources continue

to be used in the event of a SIP Application Module failure. The

RTP Media Portal is configured to “pre-register” its availability

with the Standby SIP Application Module. This configuration

enables the Standby SIP Application Module to immediately

begin utilization of the RTP Media Portal for session requests
