Abstract
A communication system with switched hub is disclosed including a set of communication ports that transfer inbound and outbound communication frames over corresponding serial communication links. The communication ports determine a destination port for each incoming communication frame and perform interleaved transfers of the incoming communication frames to a set of virtual transmit first-in first-out (FIFO) memories that buffer communication frames for outbound transfer. The mechanism disclosed enables fast and efficient switching of the inbound frames to corresponding outbound ports.
