1. A computer-implemented method for processing network packets, the method comprising: receiving network data to be transported between a first Performance Enhancing Proxy (PEP) and a second PEP, the network data being segmented in one or more original network packets; removing a header from each of the two or more original network data packets; collecting packet identifying data associated with the two or more original network packets from the removed header before the network data is packetized into one or more performance enhanced packets by the first PEP, the packet identifying data comprising information regarding the segmentation of the network data into the two or more original network data packets; and transmitting the packet identifying data to the second PEP.
