GGSN9811 Software Structure
The GGSN9811 software architecture includes:
Local Maintenance Terminal (LMT) software, which is
installed on the PC.
Host software, which is installed in the GGSN equipment.
PC: installed with
LMT software
GGSN: installed with
HOST software

Host Software
The GGSN host software include:
XML files
The XML files are installed in the hard disk of the SRU.
The version configuration file of the host software is installed.
Host software package
It is installed in the hard disk of the SRU.
It contains the software of the main processing unit and the service
processing unit.
It is provided in the format of software package. For example, a
software package is called GGSN9811V900R008ENGC××SPC
×× .cc

Host Software
Back Administration Module (BAM)
It is installed in the hard disk of the SRU.
It is in the format of directory which contains a series of
subdirectories and files.
BootRom
It is burnt on the board chip of the GGSN9811 host and belongs to
the boot unit of the system.
The system can automatically obtain the latest software version
when you install the software to the host.
The BootRom menu provides the basic maintenance and operation
menu.

Local Maintenance Terminal
The OAM system of the GGSN9811 uses the Client/Server
architecture.
LMT is the client software, which is installed on the PC.
BAM is the server software, which is installed in the GGSN.
Together with the BAM, the LMT implements the following
functions:
Data configuration
System maintenance and operation
According to the actual requirements, you can configure one or
multiple PCs as the LMT.

LMT Service Manager
The LMT Service Manager provides the following service groupware:
FTP server
It can be set on the PC terminal to load and back up the files of the GGSN9811.
FTP client
It can upload and download software packages such as the host software.
LMT Service Manager
This describes the local maintenance terminal (LMT) service manager. The LMT service manager
enables the communication between the LMT software and the Switching Route Unit (SRU). In
addition, it can manage the server processes. You need not start the LMT service manager manually.
Convert Management system
It forwards the instruction on the alarm box by the user so that the user can operate the alarm box
through the LMT.
Monitor Viewer tool
It is used to query and browse monitor information of the system resources.
Performance Browser Tool
It is used to query and browse the information of performance management.
Tracer Viewer
It is used to query and browse the information of tracing management system.

GGSN Startup Sequence
1. The SRU board startup first.
2. The SPU/LPU startup
3. The DMPU (Daughter Mutil-purpose Process Unit )
startup after the related SPU startup.
SRU Startup
LPU Startup SPU Startup DMPU Startup

Version Software Package Usage
The *.cc file is a compressed file and is stored in the hard disk of SRU.
The *.cc file contains software packets of all boards. When a board starts up, it
downloads its software packets from SRU board to its memory.

Loading the Version Files: SRU
When the system is reset, SRU obtains its software packet from the
configured startup *.cc files. Then the software is loaded to the
memory and the new software runs.

Configuration Recovery
After the SRU starts up, the configuration management
module reads configuration commands from the
configuration files and then recover the configuration
one after one.
In the configuration files, the commands related to
interfaces cannot run immediately. The commands are
stored and start to run after the corresponding interface
board successfully registers.

Area Concepts
Main area:
Stores the currently running software.
Standby area:
stores the currently running software.
The main area and standby area can be “hd1:/soft/a ” or “hd1:/soft/b ”, it is set
by command software active.

Host Software Operation
Categories
Installing the Host Software
The default host software is installed in the device but you need to reinstall
the software in accordance with the actual requirements. Do not worry
about the service rollback as services are not started yet.
Upgrading the Host Software
To obtain new functions or solve problems of software, you need to
upgrade your current software. You have to consider how to reduce the
affects on the service and how to perform the version rollback.
Installing the Host Software Patch
The patch is to provide new functions or solve problems. You have to
consider how to reduce the affects on the service and how to perform the
version rollback.

4.2 Software Installing

The Items to be loaded into GGSN
To install the host software, you need to load the
host software packet, BAM, Service and XML files.
All of these files should be in the root directory of
FTP server.
The GGSN9811V900R007ENGC××B×××*.cc file
The BAM directory
The license.txt files

Host Software Installing Methods
Installing by LMT
Using the LMT to control the installing process.
Using the FTP function to transfer the BAM/.XML files/*.cc
files.
BAM (old):
for OAM
LMT: for OAM
IP
FTP client FTP server

Host Software Installing Procedure
1. Configure the networking
2. Check the equipment status
a. Connect the equipments
b. Configure the FTP function
a. Check the GGSN hardware
b. Check the GGSN version
3. Installing the host software
a. Load the software to GGSN
b. Active the new software
c. Install the new LMT (optional)
d. Synchronize the software

Connect the equipments

BootRom menu:
Password: 8011
If you don’t know the IP of SRU, and can’t login GGSN by LMT, you
can use the BootRom menu to check or change the SRU IP.

Configure the FTP Server
A. Copy the software to FTP server
The host software files are saved in the directory D:GGSN9811 of
the FTP server (LMT). If you store the software in other directory,
you should set that directory as the working directory of FTP user.
The *.XML files are description files for the host software version.
When you upload the host software, these three files must be
saved to the same root directory of the FTP server as the
GGSN9811V900R007ENGC××B×××*.cc file and the BAM folder.

Configure the FTP Server
B. Configure the FTP server function
After log in to the LMT, the system starts the FTP server
automatically.
An FTP server icon is added on the taskbar at the right
lower corner of the operating system. Right click to
configure the FTP server
You can use other FTP server
software as well.

Check the Equipment Status
A. Check the GGSN hardware
LMT command: display device
Result: every board is normal
B. Check the GGSN software version
LMT command: display version
Result: the current version
of GGSN is the old version.

Installing the Host Software (do not
understand)
Step3.1 : load the software to LPU and SPU board
Load software
Generally, the software load command is executed before the
software is activated. This is to ensure that the user can forcibly load
the software at a proper time. The software can be activated later to
shorten the activation duration.
This is optional step, you can run software active, then GGSN will
load the software to LPU and SPU, and reset the board automatically

After this command is issued to the host and executed successfully,
the active progress is displayed in the Progress Management bar.
The activation process takes a long time. After the software is
activated, the host restarts automatically.
After system restart, use display version to check the current soft
version number is correct or not.

Step3: active the new software version
