Transparent Distributed Processing

• TDP and io-pkt
  Transparent Distributed Processing (also known as Qnet) functions the same under the old io-net and new io-pkt infrastructures, and the packet format and protocol remain the same. For both io-net and io-pkt , Qnet is just another protocol (like TCP/IP) that transmits and receives packets.
• Using TDP over IP
  TDP supports two modes of communications: one directly over Ethernet, and one over IP. The straight to Ethernet L4 layer is faster and more dynamic than the IP layer, but it isn't possible to route TDP packets out of a single layer-2 domain. By using TDP over IP, you can connect to any remote machine over the Internet as follows:
