11. Network planning and design

Generic wiring

The web planning and design process is a iterative and optimized process.

Integrated voice RT11, data RT45 network cable, image and video transmission functions

The structured cabling system consists of six subsystems:

Workspace Subsystem: Terminal to Info Outlet10m

Horizontal subsystem: network port/information outlet to the patch panel on the (management subsystem) floor90m

Management subsystem:

Trunk Subsystem: Trunk fiber connecting each floor

Subsystem between equipment: core room

Buildings Subsystem 2000m

Network Analysis and Design

Five-stage web development process

Network traffic analysis

Intranet/Extranet 80/20

System Security: Vulnerability Discovery and Patch Management

Application Security: Database Security

The project itself cannot be a test field for new technologies, but mature technologies with many cases should be used.

Network structure and function

Three-tier architecture

LAN core switch: high performance, fast forwarding

LAN Aggregation Switch: Policy and Routing Control

LAN Access Switch: User Access and Security Control (Authentication)

WAN access technology

PSTN 56Kbps

ISDN: BRI=144K PRI= 2.048M

HFC cable modem access backbone fiber, user copper

(Cable Modem is used at the client end, and CMTS is used at the central office to control and manage users)

PON ONU and OLT

ADSL Frequency Division Multiplexing (ADSL Modem)

Interconnect Technology DDN

SDH STM1=155M

Network troubleshooting and troubleshooting

Ohmmeter/Digital Multimeter: Cable (Twisted Pair)Near-End Crosstalk
