Packets transfer device that intelligently accounts for variable egress channel widths when scheduling use of dispatch bus by egressing packet streams

摘要

In PCI-Express and alike communications systems, data bandwidth per channel can vary as a result of negotiated port aggregation and/or bifurcation during network bring-up. Disclosed are systems and methods for opportunistically interleaving dispatches of packet data for secondary egress channels when the data bandwidth of a primary egress channel is relatively small and thus creates slack on a dispatch bus between dispatches of primary data blocks.
