Abstract

Techniques are provided to allow for efficient data packing under certain coding schemes, e.g., when an enhanced 64/66 encoding scheme is employed. The traditional 64/66 encoding scheme uses idle bytes to pad packets to obtain a packet of fixed size, thereby adding idle overhead to transmitted packets. Accordingly, the techniques eliminate padding bytes and provide for receiving packets by way of a first data link at forwarding device. The packets are transmitted using a scheme that pads the packets to achieve a predetermined packet length. The padding is removed from the received packets to obtain unpadded packets. Data segments of the unpadded packets are concatenated for forwarding in a continuous data stream with a packet delimiter separating each of the unpadded packets. The continuous data stream is encoded using enhanced physical coding sub layer for forwarding over a second data link.
