Claim:
1. A method for packet flow modification, the method comprising: receiving one or more packets associated with a packet flow; modifying payload information in the one or more packets; receiving a subsequent packet associated with the packet flow; and modifying transport layer or higher layer information in the subsequent packet using information associated with the modified payload information or the packet flow, wherein modifying transport layer or higher layer information in the subsequent packet includes adjusting sequence identifying information in the subsequent packet based on the modified payload information in the one or more packets, wherein adjusting the sequence identifying information includes modifying a sequence identifier using a delta byte length value associated with the modified payload information, wherein packet flow modification is performed at line rate or near line rate by avoiding de-packetization of the subsequent packet into a data stream prior to adjusting sequence identifying information in the subsequent packet.
