PACKET TRANSMISSION METHOD AND DEVICE BASED ON PCIE BUS

摘要

Provided are a packet transmission method and device based on a PCIE bus, the method comprising: receiving a data transmission request, and determining, according to the data transmission request, whether the data to be transmitted requested by the data transmission request satisfies a condition for compression; if yes, then encapsulating the data to be transmitted in at least two data packets; the compressed transaction layer packet (TLP) lacks at least one field, or at least one field of the compressed TLP is configured with compression information; setting the data identifiers of the at least two data packets to be of the same value; transmitting the at least two data packets to a device on the opposite end via the PCIE bus. The packet transmission method and device based on the PCIE bus provided in an embodiment of the present invention save channel resources during transmission.
