Patent 7668162 was granted and assigned to QLogic on February, 2010 by the United States Patent and Trademark Office.
Method and system for processing a source protocol data unit (PDU). A local router receives the source PDU and determines whether to compress the source PDU or send the source PDU without compression. Where the source PDU is to be compressed, the local router compresses the source PDU and sets a flag indicating that the source PDU is compressed. The local router then transmits the compressed source PDU via a network link.
