Abstract
One embodiment of the present invention provides a system that facilitates end-to-end quality of service (QoS) between a source and a destination in a network. During operation, the system allocates virtual channels on an output port of a switch to a number of quality of service (QoS) levels. The system further assigns a virtual channel to a traffic flow based on a QoS zone, wherein the QoS zone is identified by a host identifier, a target identifier, and a QoS level of the traffic flow. In addition, the system forwards data frames in the traffic flow via the assigned virtual channel.
