ABSTRACT:
An apparatus and method for implementing comprehensive QOS independent of the fabric system is disclosed. According to one embodiment, a system is provided comprising a switching medium, a plurality of line cards, a first scheduler associated with an ingress line card, and a second scheduler associated with an egress line card and communicatively coupled with the first scheduler. According to another embodiment, a line card is provided comprising a plurality of input buffers, a plurality of output buffers, output buffer status logic coupled to the output buffers operable to produce output buffer status information corresponding to each output buffer, a first scheduler coupled to the input buffers and operable to select data from the input buffers based upon the output buffer status, and a second scheduler coupled to the output buffers and operable to select data from the output buffers in accordance with Quality of Service requirements.
