Systems and methods are presented relating to a three stage crossbar based switching system and a scheduling method for transmission of data packets and associated request and grant tokens. The first stage and third stage portions of the switching system contain TDM crossbars, which are interconnected by a middle stage set of crossbars. In an embodiment, the system switching module is a mxm crossbar switch comprising m inputs and m outputs. The switch has a size m formed from mxm crossbar modules. Scheduling of data packet servicing is on a frame by frame basis relating to selection based on port addresses and port address groups. Further, time slot interchange is utilized to address time slot mismatch.
