Management apparatus, communication system, and communication method

A communication system for transferring a packet from a source apparatus to a destination apparatus, the communication system comprising:

• a plurality of detection apparatuses disposed on a communication path of a connection between the source apparatus and the destination apparatus, each of the plurality of detection apparatuses including a first processor to
• detect a loss of the packet,
• transmit a notice of the loss of the packet upon detecting the loss of the packet, and
• transfer the lost packet to the destination apparatus upon receiving the lost packet;
• and
• a management apparatus including a second processor to
• acquire, upon receiving the notice from a first detection apparatus, the lost packet from a second detection apparatus disposed on a communication path between the source apparatus and the first detection apparatus, and
• transmit the lost packet to a third detection apparatus disposed on a communication path between the first detection apparatus and the destination apparatus.

A communication method for transferring a packet from a source apparatus to a destination apparatus, the communication method comprising:

• detecting, by a first detection apparatus, a loss of the packet;
• transmitting, by the first detection apparatus, a notice of the loss of the packet to a management apparatus upon detecting the loss of the packet;
• acquiring, by the management apparatus, the lost packet from a second detection apparatus disposed on a communication path between the source apparatus and the first detection apparatus upon receiving the notice;
• transmitting, by the management apparatus, the lost packet to a third detection apparatus disposed on a communication path between the first detection apparatus and the destination apparatus;
• and
• transferring, by the third detection apparatus, the lost packet to the destination apparatus upon receiving the lost packet.
