Chapter 3 Software Architecture

3.1 Overall Architecture

The MRS6100 uses the hierarchical modular software architecture from the top down.
The design focuses on integration. This ensures that the system is highly reliable,
easy to maintain, and easy to expand. The MRS6100 is also a distributed software
system. It runs on the MCCU, MSU and the VPS.
Logically, the MRS6100 software system consists of three modules:
Call processing subsystem
Media processing subsystem
System support subsystem
Figure 3-1 shows the software architecture of the MRS6100.

I. System support subsystem
This subsystem is the software platform of the MRS6100. It uses HUAWEI distributed
object-oriented programmable real-time architecture (DOPRA) platform middleware
to provide the application layer with the uniform APIs.
Also, the support subsystem provides the upper layer with the implementation
mechanisms on the following functions:
O&M
Alarm management
Traffic statistics
Signaling and user tracing
Data backup
Board switchover
Online loading
