According to HCIP Datacom Campus Network architecture principles, campus networks can be classified from multiple dimensions to support scientific planning, design, and deployment. These classification methods help network designers select appropriate architectures, devices, and technologies based on actual service requirements.

Network scaleis a primary classification dimension. Campus networks are commonly divided into small, medium, and large-scale networks based on the number of users, terminals, access points, and network devices. This classification directly influences topology design, such as whether a simple two-layer architecture or a more scalable three-layer architecture is required.

Served objectsis another important classification method. Campus networks may serve office users, guests, teaching staff, students, production terminals, IoT devices, or video surveillance systems. Different served objects have different requirements for bandwidth, security, and access control, making this dimension critical for policy and service design.

Access moderefers to how users and devices connect to the campus network, including wired access, wireless access, or a hybrid of both. This classification impacts WLAN planning, authentication methods, and network access control strategies.

Service complexityreflects the types and number of services carried by the network. A campus network may provide basic data services or support complex services such as voice, video, cloud access, and industry applications. Higher service complexity requires more advanced network design and management capabilities.

Therefore, all listed options are valid classification methods for campus networks.
