Bit-aligned Header Compression For Ccn Messages Using Dictionary

Abstract

One embodiment provides a system in a first node that facilitates efficient packet forwarding. During operation, the system stores, in a storage device in a first node, a static dictionary comprising a mapping between a type and length (TL) string and a byte-aligned compressed replacement string. The system encodes the byte-aligned compressed replacement string based on an encoding technique to generate a bit-aligned encoded replacement string and stores a mapping between the encoded replacement string and the TL string in an encoded dictionary. If the system identifies the TL string in a packet, the system replaces the TL string with the encoded replacement string and transmits the packet to a second node storing the encoded dictionary in a local storage device, thereby facilitating bit-aligned compression of a TL string.
