Link layer device with non-linear polling of multiple physical layer device ports

摘要

In a communication system comprising a link layer device connectable to one or more physical layer devices, at least a given one of a plurality of ports of the one or more physical layer devices is designated as a port for which status information is to be requested by the link layer device on a more frequent basis than such information is to be requested for one or more other ports of the plurality of ports. The ports are then polled by the link layer device in accordance with a non-linear polling sequence such that the at least one designated port is polled more frequently than the one or more other ports. The designated port may comprise a port to which the link layer device transmits data in conjunction with a current data transfer. The non-linear polling sequence may thus be altered dynamically based on particular data transfers that are occurring between a link layer device and a physical layer device in a communication system.
