Communication control apparatus and communication control method

A communication control apparatus connected to a content-oriented network, the communication control apparatus comprising:

• a transmitter that transmits an interest packet requesting a plurality of pieces of content;
• a receiver that receives a first data packet including (i) a first piece of content, which is one of the plurality of pieces of content corresponding to the interest packet, and (ii) first pending interest table (PIT) information representing a name of a second piece of content, which is another of the plurality of pieces of content corresponding to the interest packet and which has not been transmitted from a transmission source;
• a memory that stores a transmission PIT in which names of the plurality of pieces of content requested by the interest packet, transmitted by the transmitter, are registered;
• and
• a processor that registers, in response to transmission of the interest packet by the transmitter, the names of the plurality of pieces of content requested by the interest packet in the transmission PIT, and that deletes, in response to reception of the first data packet by the receiver, a name of the first piece of content included in the first data packet from the names of the plurality of pieces of content registered in the transmission PIT, wherein
• the processor detects packet loss based on the first PIT information included in the first data packet and the transmission PIT.
