Abstract
Systems and methods for providing fractional bandwidth communication channels in classes of service that do not normally support these types of channels. In one embodiment, a method comprises receiving one or more frames, wherein each frame contains non-QoS header information, classifying the one or more frames based on the corresponding non-QoS header information and scheduling delivery of the one or more frames based upon corresponding frame classifications, wherein frames in classifications corresponding to QoS circuits are scheduled in a manner that meets QoS requirements associated with the QoS circuits. When the frames are classified, they are forwarded to dynamically allocated queues corresponding to the respective classifications. Frames are scheduled for delivery from the queues according to a modified bin-filling algorithm that is designed to meet the QoS requirements of the respective circuits. This method may be implemented, for example, in a Fibre Channel Class 2 or Class 3 fabric.
