Provided are a system and method for realizing end-to-end Hierarchical Quality of Service (HQoS), which overcome the problem that prior art cannot ensure the normal implementation of egress HQoS scheduling function. The method is applied in a distributed system, and co mprises: when a transmitter has packets to be transmitted, it sends a forwarding request to a receiver; the receiver performs Hierarchical Quality of Service scheduling after receiving the forwarding request, and replies to the transmitter an authorization response when determining that the transmitter is allowed to transmit the packets; after receiving the authorization response, the transmitter transmits the packets to be transmitted to the receiver. Application of the system and method to perform end-to-end hierarchical QoS control ensures the egress HQoS scheduling function and the Quality of Service of user services. |
