Abstract
A gigabit network node having a media access controller outputting data frames at gigabit rates uses multiple 100 MB/s media interface links coupled to a physical interface to enable implementation of a gigabit network using low cost data links. A modified reconciliation layer, also referred to as a media interface, receives a data frame from a gigabit MAC and selectively stores the received packet data into one of a plurality of transmit buffers associated with the respective 100 MB/s media interface links, according to a path selection arbitration logic in the media interface. The path selection arbitration logic may operate according to an equal priority scheme, where each received data frame is routed according to a round-robin scheme. A high priority/low priority scheme may also be used by the path selection arbitration logic, where data frames identified as high priority are temporarily stored in a high priority transmit buffer, and then forwarded to a selected one of the transmit buffers associated with a corresponding 100 MB/s media interface link before outputting data frames from a low priority buffer.
