Ne Software - Huawei OptiX OSN 7500 Technical Manual

OptiX OSN 7500
Technical Manual - System Description
provides SDH-based protection for services. The control plane serves as one client of
the service plane. Through the interface adaptation mechanism, the resource agents
of the control plane and the service plane interact with each other to get the status of
resource allocation and implement function provisioning of the NE.

NE Software

The NE software is used to manage, monitor and control the operation of the boards
of an NE. Through the NE software, the communication unit between the NM system
and boards, the NM system can control and manage NEs. According to ITU-T
Recommendation M.3010, the NE software belongs to the unit management layer in
the telecommunication management network, implementing the functions including
NE functions, some of coordination functions and operating system functions of the
network unit layer. The data communication function implements the communication
between the NE and other equipment (including coordinated equipment, NM system,
and other NEs).
The function of the real-time multi-task operating system of the OptiX OSN 7500 NE
software is to manage public resources and provide support for the executive program.
It can provide an executive environment unrelated to processor hardware by
segregating the application from the processor.
The NS module is between the communication module and equipment management
module. It converts the data format between the user operation side on the application
layer and the NE equipment management layer, and provides security control for the
NE layer. It can be divided into three sub-modules functionally: Qx interface module,
command line interface module and security management module.
The equipment AM is the kernel of the NE software for implementing NE management.
It includes Manager and Agent. Administrator can send network management
operation commands and receive events. Agent can respond to the network
management operation commands sent by the network administrator, implement
operations to the managed object and submit events according to status change of
the managed object.
The equipment AM includes configuration management module, performance
management module, alarm management module and MSP switching management
module.
This module fulfills the message communication function (MCF) of the functional
blocks of the transmission network equipment.
