CHAPTER 3. System Structure

3-20

Common Performance Management (OPM)

OPM collects and provides the performance data for the upper management system

operator to know the SPI-2L10 performance. The OPM collects the event generated during

the system operation and the performance data and transmits them to the management

system. The collection cycle of the statistics data of the actual OPM can be set as 15

minutes, 30 minutes, 60 minutes, and if the entire statistics file of the binary format is

created every 15 minutes, the management system collects it periodically via the FTP/SFTP.

Main functions are as follows:

y Record and collect statistics data

Record statistics data to the memory and generate the statistics file by regularly

collecting data per each board

y Save the statistics data

Save the statistics data of each board in its own nonvolatile storage during up to eight

hours

y Inquire and change the statistics configuration information

Inquire and change the collection cycle (BI) and the threshold of the statistics data

y Threshold Cross Alert (TCA)

Generate the TCA (Critical, Major, Minor) according to the defined threshold in every

collection cycle and report it to the UFM

y Monitor the statistics in real time

Provide the real-time monitoring function for the specific statistics item designated by

the operator

Common Subscription Service Management (OSSM)

OSSM distributes the PLD data necessary for the software blocks, and reports the data

changed to the corresponding software block if PLD data are changed. Also, it supports the

function to maintain the consistency of PLD data that are scattered in the system.

Main functions are as follows:

y PLD distribution

OSSM loads PLD to the shared memory for software block in order to access PLD

y PLD change report

Report the changes of PLD to the corresponding software block

y PLD audit

Maintain the consistency of PLDs which are distributed in the SPI-2L10 (between

main board and lower boards)
