The disclosed systems and methods relate to allocating bandwidth to a plurality of ports that access a shared resource. An exemplary system may comprise a multiplexer, a table, and a scheduling circuit. The table may define when a port has access to the shared resource. The table entries may be based on the number of ports with access to the shared resource and the required bandwidth in each of the ports. The scheduling circuit controls the multiplexer according to the table, and the ports may gain access to the shared resource one port at a time.
