<p class="MsoNormal">Somehow, plc network device or channel don't support working with multiple protocols. If you check NetDeviceFace::Send, you'll see that Send operation specifies "L3Protocol::ETHERNET_FRAME_TYPE" as a protocol number. During registering
ndn protocol, NetDeviceFace::RegisterProtocolHandlers, the same protocol was specified. Somehow, inside PLC module when packet arrives, it does not carry the proper protocol number and without the hack I suggested, NS-3 cannot properly dispatch packets to
ndnSIM.<o:p></o:p></p>
