First Claim
Patent Images
1. A per-flow rate controller, comprising:
- a queue classifying unit, receiving a plurality of frames through a plurality of per-flow paths and classifying the frames according to a source port address or port number of each per-flow path;
a queue memory unit, comprising a plurality of queues, and storing the frames into each queue according to a classifying result of the queue classifying unit; and
a queue selecting unit, selecting the transmitting index between queues, and determining the traffic output throughput rate of each of queue according to the traffic throughput control table so as to control the transmitting rate of each per-flow path.

Abstract
A per-flow rate controller is disclosed. The controller includes a queue classifying unit, a queue memory unit and a queue selecting unit. The queue classifying unit receives a plurality of per-flows and then classifies them by the source port address of each per-flow group. The queue memory unit includes a plurality of queues. The queue memory unit stores the packets into corresponding queues according to the classifying result of the queue classifying unit. Finally, the queue selecting unit selects the queue for frame transmission and controls the output throughput rate of each queue according to user settings.
