Have a deep understanding of the configuration and application between routers, switches and PCs, master some simple network applications and connections, and master the basic configuration of routers and switches; Master DHCP, ACL, VLAN and NET protocols and corresponding technologies; Improve the ability to analyze and solve practical network problems. The design needs to be divided into four sub-network levels for cell-based network communication. Using the software cisco, we can better realize the cooperation and contact between different network devices, so as to achieve the best communication effect in the LAN.

Curriculum design requirements:

It is required to draw a topology diagram according to the actual problem, which can be one of tree, star, mesh, ring and mixed structure, clearly describe the interface and realize the code configuration of the router or switch. Each scheme needs the following parts:

1, description of demand characteristics;

2. Design principles;

3, scheme design, which must include:

(1) equipment selection;

(2) Integrated wiring design;

(3) Topology diagram;

(4)IP address planning;

(5) Subnet division;

(6) Selection of routing protocol;

(7) Router configuration.

General requirements for building a local area network:

Using my own understanding of LAN networking technology, I designed a community networking scheme, so that a wireless city can have 200 home nodes for network communication, and the whole community can be divided into four areas:

1. Network central area: the core switching equipment and server group mainly composed of property management center and monitoring center;

2. Remote network access area: router equipment and network security equipment including external network access ports;

3. Park network area: including backbone exchange equipment from network center to community service facilities;

4. Home network area: including backbone switching equipment from the network center to the building, providing network access ports for each family unit, which is the most basic unit of the whole community network system.
