I want to improve transfer time between several machines in the same LAN
via manipulate Ethernet frame directly,because neither the Qnet Msg passing
nor TCP/IP stack speeds can’t statify our communication
requirements(transfer a size of 60Bytes package to 12 client machines in
every control cycle–1ms).On the other hand,it can improve transfer time via
multicast of Ethernet specification .
Do you think my idea feasibly???
Now I have got the technical specification of my NIC card,doesn’t I need
to stop the original driver of the NIC(3COM 905B-TX-NM) and then run my
portable ‘driver’ (I propose to write some codes to manipulate the NIC ) ??
And thanks for any idea of improving transfer time under QNX 6.20 PE in
Institute of Plasama Physics of Chinese Academy.
