Disadvantages of Campus Area Networks (CANs)

Campus area networks (CANs) provide widespread connectivity within a localized area, but they come with certain disadvantages that should be considered.

1. Complex Design and Management:
CANs require meticulous planning and implementation, as they span multiple buildings, devices, and users. The complex network architecture can be challenging to configure, maintain, and troubleshoot, especially in large or rapidly evolving campuses.

2. Cybersecurity Risks:
The extended reach and accessibility of CANs increase the exposure to cybersecurity threats. The vast number of connected devices creates potential entry points for unauthorized access, making them vulnerable to cyberattacks, data breaches, and malicious software.

3. Physical Infrastructure Dependence:
CANs rely heavily on physical infrastructure, such as cables, switches, and routers. Any damage, disruption, or failure of these components can cause network outages, affecting connectivity and services across the campus.

4. Ongoing Maintenance:
CANs require continuous maintenance to ensure optimal performance and security. Regular updates, firmware patches, and hardware replacements are essential to keep the network running smoothly, which can be a significant expense over time.

5. Potential Failure Points:
The decentralized nature of CANs introduces multiple failure points. A malfunction or outage in a single node or connection can disrupt network connectivity for a portion or the entire campus, impacting critical services and academic activities.

Conclusion:

While CANs offer significant benefits in terms of connectivity, they also present challenges that must be carefully considered. The complex design, cybersecurity risks, infrastructure dependence, maintenance requirements, and potential failure points highlight the need for thorough planning, robust security measures, and ongoing management efforts to ensure the stability and reliability of campus area networks.
