A-msdu subframe processing method and wireless network access device

A wireless access device, comprising:

• a control circuit;
• a processor installed in the control circuit;
• a memory installed in the control circuit and operatively coupled to the processor;
• wherein the processor is configured to execute program code stored in the memory to perform operations comprising:
• allocating a first sub-block and a second sub-block adjacent to the first sub-block in a memory when an Ethernet frame is received, wherein the first sub-block comprises a block with a preset bit length, the second sub-block comprises a block with a bit length corresponding to the Ethernet frame, and a pointer initially points to a first initial address in the second sub-block;
• sequentially storing header information of the Ethernet frame into the second sub-block according to a header format of the Ethernet frame;
• filling the first sub-block with length information of the Ethernet frame;
• shifting the pointer along a first direction to a second initial address whose distance shifted from the first initial address is the preset bit length;
• and
• reading out data in a length along a second direction from the second initial address to generate the A-MSDU sub-frame, wherein the length is the sum of the preset bit length and the bit length of the Ethernet frame.
