  • Two stage internet protocol header compression
    Patent number: 8140709
    Abstract: Various exemplary embodiments relate to a method and related network system including one or more of the following: receiving a packet having a header and belonging to a flow; identifying a context identifier (CID) associated with the flow; morphing the header into a pseudo-compressed header, the pseudo-compressed header including the CID associated with the flow; determining whether the packet should be transmitted with a compressed header, a full header, or an uncompressed header; morphing the pseudo-compressed header into a compressed header to form an outgoing packet when the packet should be transmitted with a compressed header; morphing the pseudo-compressed header into a full header to form an outgoing packet when the packet should be transmitted with a full header; restoring the uncompressed header to form an outgoing packet when the packet should be transmitted with an uncompressed header; and transmitting the outgoing packet over the communications network.
