AI Technical Summary
In scenarios where switches are connected to multiple leaf nodes, existing technologies struggle to accurately limit the dedicated line traffic of terminal devices, especially in dual-homed, dual-active access scenarios, where traffic limiting cannot meet the available bandwidth requirements of terminal devices.
A combination of primary and backup leaf nodes is adopted. The primary leaf node receives and forwards the uplink traffic of the terminal device, while the backup leaf node forwards the uplink traffic to the primary leaf node. The primary leaf node performs unified preset bandwidth control to achieve monitoring and rate limiting of all uplink traffic.
In scenarios where the switch is connected to multiple leaf nodes, precise rate limiting of uplink traffic to terminal devices is achieved, ensuring that the traffic does not exceed the preset bandwidth. Furthermore, when the primary leaf node fails, the backup leaf node can switch to become the primary node and continue rate limiting.
