The UOA can logically serve as the interface between the NM level, including the I2000,

and the device level. The UOA orientation is as follows:

The following products IN, data service and value-added service have different NM

agents and functions:

The further understanding of the serviceable products calls for a standard NM mode. The

UOA is developed to unify the NM agents of the preceding products.

The UOA provides the Simple Network Management Protocol (SNMP) and the

Syslog protocol. The standard and open management of the applications is

enhanced through the SNMP and Management Information Base (MIB) of the

interface.

The UOA is located between the NM layer and the device layer.

It is the point separating the management and the operation.

The UOA adopts the extended framework of the SNMP agent and related interface.

It communicates with the devices through the internal protocols defined by the

TCP.

SNMP Agent Module

It converts the SNMP to the internal protocol.

Log Management Module

It receives the management control command forwarded by the SNMP Agent

module and forwards the log information to the I2000. If great amount of logs

exists, the data file is provided through the FTP.

Performance Data Collection Module

It receives the management control command forwarded by the SNMP Agent

module to control the performance and collects the performance data.

Message Tracing Module

It processes the messages through the TCP server, provides the access for the NEs

and the I2000, and controls the tracing.

CLI Module

It supports the remote login. Five users can log in at the same time.

It sends command to maintain the device and display the result.

LMA Module

It monitors the running status of the application process.

CLI:Command Line Interface

OAMLib:Development library of the application interface

For the management and operation, the function of the UOA includes the control

mechanism and the public application.

I2000 Interface

Interface name: F1

Interface description: The UOA can be connected to the I2000 through the SNMP.

A large number of data can be transferred through the FTP. The Syslog standard is

abided. The message tracing communicates with the I2000 through the TCP.

NE Interface

Interface name: F2

Interface description: The NEs are connected to the UOA through the OAMLib. The

protocol is internal.

CLI

Interface name: F3

Interface description: You can log in to the UOA through the TCP. You can also

enter the command to obtain the result.

cfg: configuration file of the system.

uoa_common.ini

uoa_lma.ini

uoa_log_agent.ini

uoa_snmpagent.ini

uoa_trace_agent.ini

You can also find the uoa_system.ini file under /system/ of this directory. The

uoa_system.ini file is used to set some running parameters for the UOA system.

uoa_server

The uoa_server process manages the topology links and the alarms.

The process converts the message between the SNMP protocol and the internal

protocol. It serves as an agent to process the messages between the device and

the I2000.

uoa_log_agent

To listen on the Syslog messages from the modules, the uoa_log_agent process

enables the TCP port and the UDP port at the same time.

The process sends the Syslog messages to the I2000 by the UDP based on the

related configurations and rules.

The process is connected to the OAMLIB library by the TCP. The Syslog messages

reported by the NEs are sent by this TCP channel.
