After receiving a plurality of fragmented packets over a computer network interface a computing device may reassemble data from the plurality of packets into an IP packet that includes data from each of the fragmented IP packets. The reassembled IP packet may then be compressed and encrypted before being transmitted to a computer identified in a destination address in each of the plurality of fragmented packets. ## Claims ### Claim 1 A method for optimizing the transfer of packetized data between electronic devices in a computer network, the method comprising: receiving data packets of a set comprising a plurality of fragmented internet protocol (IP) packets sent from a source computer to a destination computer for processing at the destination computer, the received set of fragmented IP packets comprising a number of bytes;
