Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0042] Aiming at using the main control CPU or network controller in the prior art to process the messages of the network equipment, the present invention adopts the method of FPGA, without adding additional hardware chips, in each port of each board card It supports subsequent fragmented packets and the first fragmented packets to be processed in the same way, so as to support high-density, high-forwarding performance frame-type network devices, and achieve high processing performance and efficient fragmented packet processing.
[0043] The present invention provides a message fragmentation processing method, adopts FPGA to process the received data message, and the fragmentation information table item is stored in the resources in the FPGA chip or in the external memory, and the content of the fragmentation information table item includes Characteristic value and f...
