In small- and medium-sized campus networks, the Huawei CloudCampus Solution focuses onsimple, flexible, and easy-to-manage traffic control mechanismsthat align with wireless access characteristics. According to HCIP Datacom Campus Network documentation, several rate limiting modes are supported to ensure fair bandwidth usage and stable user experience in WLAN environments.
Radio-based rate limitingis supported and commonly used in small and medium campuses. This mode limits the total bandwidth available on a radio interface, preventing congestion when multiple users access the same radio. It is especially effective in high-density wireless scenarios where multiple terminals compete for limited wireless resources.
SSID-based rate limitingis also supported. This allows administrators to limit bandwidth per SSID, ensuring that different wireless services—such as guest access and internal employee access—receive appropriate bandwidth allocations. This method is easy to configure and aligns well with service-oriented WLAN design.
User-based rate limitingis another supported mode. It enables bandwidth control on a per-user basis, ensuring fair usage among users and preventing individual users from consuming excessive bandwidth. This approach is particularly useful in environments like classrooms, retail stores, or offices.
ACL-based rate limiting, however, is not typically used or recommended in small- and medium-sized CloudCampus WLAN scenarios. ACL-based rate limiting is more complex and is generally applied in wired or advanced traffic engineering environments rather than simplified campus WLAN deployments.
Therefore, the supported rate limiting modes areRadio-based,SSID-based, andUser-based, makingA, C, and Dthe correct answers.
