Project 2: Building a Small Campus Network Using Switches
1. Learning Objectives and Requirements
Switch technology plays a pivotal role in modern high-speed networks, with enterprise networks relying on switches to segment networks and achieve high-speed connections. Switches are classified into multiple levels, generally Layer 2 and Layer 3 switches. Layer 2 switches are data link layer devices that recognize MAC address information in packets, forward based on MAC addresses, and record these MAC addresses with corresponding ports in an internal address table. The most important function of Layer 3 switches is to accelerate fast forwarding of data within large LANs, incorporating routing forwarding capabilities. Switches have wide applications: in simple scenarios, they can replace hubs as central connection points for multiple hosts; in complex applications, switches can connect to one or more other switches to establish, manage, and maintain redundant links and VLAN connectivity. Through learning and practice in this chapter, students will become familiar with switch configuration and proficient in switch management and maintenance.

Project 3: Building a Medium-Sized Campus Network Using Routers
1. Learning Objectives and Requirements
Routers are indispensable network devices connecting various LANs and WANs on the Internet. They automatically select routes based on the overall network communication situation, sending information to other network devices in the best path and in sequence, thereby achieving routing and forwarding of information. The continuous expansion of network scale provides a good foundation and broad platform for the development of “routing.” As the Internet’s requirements for data transmission efficiency increase, the role of “routing” in network communication becomes increasingly important.
Routers provide mechanisms for heterogeneous network interconnection, enabling data packets from one network to be sent to another. Routing is the path information guiding IP packet transmission. Routing protocols are pre-agreed rules and standards in the process of guiding IP packet transmission. Routing protocols support routable protocols by sharing routing information between routers. Routing information is passed between adjacent routers, ensuring all routers know paths to other routers. In summary, routing protocols create routing tables describing network topology; routing protocols work with routers to perform route selection and packet forwarding. In practical applications, routers typically connect many different networks; to achieve communication between multiple networks, routing protocols must be configured on routers.
