A method and device for multiplexing a stream of packets containing uncompressed and compressed packets. In a compressed packet, an identification bit pattern is inserted between the compressed payload data and the transport header so that a decompressor can determine whether the packet is compressed based on the presence of the identification bit pattern. Because the compressed packet carries the original transport header of a packet with minor modification, an intermediate node on the path of packet can see information in the transport header. In contrast, the transport header in an IPComp packet is part of IP payload and thus compressed.
