Abstract:
1. A method of transmitting digital data over a network comprising: receiving a plurality of packet data units; identifying at least two of the plurality of packet data units that have a same aggregation identifier; forming an aggregate packet from the at least two of the plurality of packet data units; and transmitting the aggregate packet to at least one destination node; wherein the aggregate packet comprises an aggregation header that comprises a number of packet data units in the aggregate packet, further comprising: determining the presence of a checksum bit in a media access control header; calculating a first checksum for the aggregation header; comparing the first checksum to a second checksum that is received in the aggregation header of the aggregate packet; receiving the aggregate packet, wherein the aggregate packet comprises the media access control header; determining the presence of an original frame check sequence bit in the media access control header; and passing the at least two of the plurality of packet data units to a device without modifying frame check sequences if the second checksum is found to be correct.
