Abstract
A method for routing frames is provided. The method comprises: receiving a frame at a receive port segment of a port for a switch element; generating a tag based on information included in the frame, where the tag identifies a location where the frame is stored in the receive port segment; transmitting the tag to a destination port for the frame; generating a request for the frame, wherein the destination port generates the request for the frame; transmitting the request for the frame to the port that received the frame, where a field in the request differentiates the request for the frame from the tag generated by the receive port segment of the port that received the frame; and transmitting the frame stored at the receive port segment, in response to the request sent by the destination port.
