ABSTRACT:
In the communication control unit lower layers communication control device includes first and second buffers. When MAC frames are received, these are input to the first buffer. By contrast, when LLC frames are received, these are first input to the second buffer, and then, transfered into a shared memory through output means. The second buffer operates as a ring buffer scheme and LLC frames can be received without missing any one after another in this unit, as long as the second buffer has enough capacity. Furthermore, only LLC frames are stored in the second buffer, thus enabling simplification of buffer management.
