Transmission apparatus and transmission method

A transmission apparatus comprising:

• a priority packet generating part of generating a priority packet from priority data transmitted by priority;
• a non-priority packet processing part of processing a non-priority packet having a lower transmission priority than said priority packet;
• a transmit packet control part of deciding transmission timing of said priority packet and said non-priority packet;
• a transmit frame processing part of performing transmission processing of said priority packet and said non-priority packet;
• a receive frame processing part of performing receipt processing of a receive frame received from a network;
• and
• a receive packet sorting part of sorting a receive packet and transferring said non-priority packet to said non-priority packet processing part, wherein
• said non-priority packet processing part acquires header information of said priority packet from said receive packet and sets said header information in said priority packet generating part.

A transmission method comprising:

• a step of transmitting a priority packet to be transmitted by priority and
• steps of transmitting and receiving a non-priority packet having a lower transmission priority than said priority packet, wherein
• in the steps of transmitting and receiving said non-priority packet, header information of said priority packet is acquired and
• in the step of transmitting said priority packet, header information of said priority packet is set at said priority packet and transmitted.

A transmission method comprising:

• a receiving step of receiving a receive packet consisting of a priority packet to be transmitted by priority and a non-priority packet having a lower processing priority than said priority packet;
• a sorting step of sorting said receive packet into said priority packet and said non-priority packet by inspecting a communication protocol header stored in said receive packet;
• and
• a processing step of processing said priority packet and said non-priority packet separately.

A transmission apparatus comprising:

• a priority packet generating part of generating a priority packet by adding an error correction code to priority data to be transmitted by priority;
• a non-priority packet processing part of generating a non-priority packet having a lower transmission priority than said priority packet;
• a transmit packet control part of deciding transmission timing of said priority packet and said non-priority packet;
• a transmit frame processing part of performing transmission processing of said priority packet and said non-priority packet;
• and
• a receive frame processing part of detecting transmission failure from network and notifying it to said transmit frame processing part, wherein
• in the case where transmission of said priority packet is delayed due to said transmission failure, said transmit packet control part thins out and transmits said priority packet in which said error correction code is stored.

A transmission method comprising:

• a priority packet transmitting step of transmitting priority packet by adding an error correction code to priority data to be transmitted by priority and transmitting it as a priority packet;
• and
• a non-priority packet transmitting step of transmitting non-priority packet by transmitting a packet having a lower transmission priority than said priority packet as a non-priority packet, wherein
• in the case where transmission failure occurs on a transmission path, in said priority packet transmitting step, said priority packet in which said error correction code is stored is thinned out and transmitted.

A transmission apparatus comprising:

• a receive frame processing part of receiving a priority packet which stores priority data to be processed by priority and a non-priority packet having a lower processing priority than said priority packet and performing receipt processing of a receive frame;
• a receive packet sorting part of sorting the receive packet stored in said receive frame into said priority packet and said non-priority packet;
• a defragment processing part of performing defragment processing of at least said priority packet;
• and
• a priority data processing monitoring part of issuing a priority data processing completion notice that notifies completion of processing of said priority data, wherein
• said defragment processing part finishes defragment processing of said priority packet needed to have been processed by the time of receipt of said priority data processing completion notice.
