Disclosed are a compression/decompression method and device of Ethernet header. The compression method comprises: identifying the packets needing to be compressed and the common packets at a data packets transmission end, comparing and calculating the packets needing to be compressed and the packets from a local compression table, generating the corresponding compression number of the packets needing to be compressed for subsequent transmitting, and transparently transmitting the common packets. The decompression method comprises: identifying the packets needing to be decompressed and the common packets at a data packets receiving end, extracting the corresponding packets from a local decompression table according to the corresponding compression number of the packets needing to be decompressed, comparing and calculating the packets needing to be decompressed and the packets extracted from the local decompression table to recovery the original packets. Application of the present invention compresses the Ethernet data to increase the bandwidth utilization of the air interface, a simple and effective solution reducing the implementation complexity and the packets transmission delay. |
