Abstract

The present invention provides a CRC calculation method and system for heterogeneous protocol conversion, relating to the technical field of data processing, including: obtaining the initial protocol data packet to be converted; decoding the initial protocol data packet to be converted, and verifying the initial protocol data packet based on the decoding result Whether the transmission of the protocol data packet to be converted is correct; if the transmission of the initial protocol data packet to be converted is correct, then based on the conversion requirements of the target protocol, the header data in the initial protocol data packet to be converted is modified to obtain the intermediate protocol data packet to be converted, wherein , the modification operation includes at least one of the following: adding data operations, deleting data operations, and replacing data operations; calculating the CRC check value of the intermediate protocol data packet to be converted, and updating the CRC check value to the intermediate protocol data packet to be converted , to obtain the target protocol data packet to be converted. It solves the technical problems of long time consumption and low efficiency of heterogeneous protocol conversion in the prior art when performing CRC code calculation for heterogeneous protocol conversion.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a CRC calculation method and system for heterogeneous protocol conversion. Background technique [0002] Heterogeneous protocol conversion usually involves a variety of network protocols, such as Ethernet protocol, FC protocol (FiberChannel, Fibre Channel), RapidIO protocol, etc. In the process of protocol conversion, conversion between several protocols may be involved. The network protocol is converted to the RapidIO protocol, which involves how to complete the bit field mapping of the data frame format between different protocols. It is necessary to add, delete, and change the data information such as the packet header of the received data packet to complete the package and Unpack. Cyclic redundancy check method is used in cross-heterogeneous protocol switching system to ensure the correctness of data during transmission. CRC (Cyclic Redundancy Code, Cyclic Redundanc...
