COMPRESSION AND DECOMPRESSION METHODS OF ETHERNET HEADER AND CORRESPONDING DEVICES

摘要

An Ethernet header compression/decompression method and device. At a data packet transmission end, a packet which needs to be compressed and a common packet are identified, the packet which needs to be compressed is compared with a packet from a local compression table, a compression number corresponding to the packet which needs to be compressed is generated for subsequent transmission, and the common packet is transmitted transparently. At a data packets receiving end, a packet which needs to be decompressed and a common packet are identified, a packet is extracted from a local decompression table according to the compressing number corresponding to the packet which needs to be decompressed, the packet which needs to be decompressed is compared with the packet extracted from the local decompression table to restore the original packet.
