ABSTRACT
This report analyzes the whole process of requirements analysis, design,
construction, testing and application of the campus network from the
perspective of engineering projects. The report first analyzes and plans the
needs of the campus network, and preliminarily determines the construction
plan of the project according to the needs of the actual campus network and the
existing equipment. Next, the modular test is carried out according to the main
actual models, familiar with the functions and characteristics of each module,
and proficient in the configuration instructions of HyperTerminal. The main test
modules include the following:
1. Suppress broadcast storms through VLAN division and realize the need for mutual
communication between different VLANs.
2. Setting parameters and functional characteristics of each port of the three-layer
switch.
3. Communicate with each other between VLANs through static routing and RIP
protocol.
On this basis, the final network design scheme is summarized and proposed:
1. The point-to-point line connection between Layer 3 switches serves as the WAN
backbone.
2. The campus network uses the connection between Layer 3 switches as the topology
backbone.
3. Suppress broadcast storms and manage subnets through VLAN division.
4. Add DHCP server, FTP server, ACL and other practical network applications.
After that, the process design and planning is carried out according to the overall plan
to ensure the progress of the project. In this way, the construction of the network
topology diagram was basically completed, and then the test and modification were
carried out, and the engineering project was basically completed. Finally, the course
