<title>LAN Technology</title> Integrated cabling technology of LAN technology

Workspace Subsystem : Is the subsystem that connects the user terminal equipment, mainly including the information socket and the adapter between the information socket and the equipment. Popular is the connection between the computer and the cable interface between the part.

Horizontal Subsystem : Is the subsystem that connects the work area and trunk mainly includes the wiring frame, the wiring cable and the machine socket. In layman's terms, from the inside of the floor of the weak between the wiring frame to each room wall card interface between the part. It is usually routed above the ceiling, so it is parallel to the floor, so it is called the horizontal subsystem.

Management Subsystem : is a subsystem for terminating and configuring management of cabling cables. In general, it is a part of the equipment between the wiring.

Trunk Subsystem : A subsystem used to connect between the management and the device. In layman's terms, the switch of the access layer is connected to the network line of the distribution layer and the core Layer switch section.

Inter-device subsystem : Refers to some systems that install equipment. In general, a large building has one or more devices, usually the core of the switch is placed here.

Complex Subsystem : It is used to connect the subsystems between the buildings. Includes a variety of communication transmission media and knowledge equipment. Because it is outdoors, it is often referred to as an outdoor subsystem.

Network system Construction

Network Engineering Formation:
1. Network Requirements Analysis

2. Network system Scheme Design

• 0 overall design goals and principles
  
  • The overall goal of network design should be to identify which network technologies and network standards are used, and to build networks that meet which applications are or how large
  • If the network engineering has to be implemented in phases, it should also clarify the objectives of the phased project, the content of the construction, the project cost time and schedule, etc.
    -Overall design principles, the main design principles should be selected and balanced before design, and determine the priority of the design, the design of the network and the implementation of the project is instructive
  • -Practical principles
  • -The principle of openness
  • -High Availability principle
  • -Safety Principles
  • -Advanced principle
  • -Ease of Use principle
  • -The principle of scalability
• 0 Hierarchical structure Design
  
  • -Core Layer
  • -Access Layer
  • -Distribution Layer
• 0 Network Equipment Selection
  
  • -Manufacturer's Choice
  • -Scalability Considerations
  • -According to the practical choice of the scheme
  • -High cost-effective products
• 0 Network Security Design
  
  • -According to the basic principles of safety design
  • -The cask principle of network information security and confidentiality
  • -Principle of wholeness
  • -Principles of practicality and effectiveness of network security systems
  • -The principle of hierarchy
