Abstract
Computing devices and methods for transmitting and receiving optimized tunneling IP packets. At the entry point of a tunnel, an IP packet comprising at least one header is received. If data comprised in one of the at least one header of the received IP packet are redundant with data comprised in one or more tunneling header of a tunneling IP packet, then the redundant header is removed from the received IP packet. The tunneling IP packet encapsulating the received IP packet (with its redundant header removed) is transmitted. A header removal field is positioned in the tunneling IP packet to indicate the positive determination of redundancy. At the exit point of the tunnel, the tunneling IP packet is received. The header removal field and the one or more tunneling header of the tunneling IP packet are used for identifying the previous determination of redundancy and recreating the removed header.
