Communication system, distribution device, data distribution method and program

A distribution device provided in a communication system that includes:

• a single or a plurality of line switching networks that transfers data received through a line generated corresponding to a transmission destination of data and a single or a plurality of packet switching networks that transfers data through a route corresponding to the transmission destination of data among a plurality of routes;
• a service providing device that provides a service to a user;
• and
• a calculation device having at least a communication function and an arithmetic processing function, wherein
• the distribution device selects one of the line switching network or the packet switching network as a distribution destination on a basis of distribution policy information in a case of connecting to the line switching network and the packet switching network and receiving data to which the service providing device or the calculation device is set as a transmission destination, transmits the received data to the selected switching network, captures the received data on a basis of aggregation policy information in a case where the data transmitted by another one of the distribution devices is received from the line switching network or the packet switching network, and transmits the captured data to the service providing device or the calculation device corresponding to a transmission destination of the captured data, wherein the aggregation policy information indicates an aggregation policy for (i) time division reception, in which a receiving destination is switched in time, (ii) simultaneous reception, in which data is received from multiple destinations simultaneously, or (iii) selective reception, in which the receiving destination is selectively switched according to priority.

A data distribution method, comprising:

• by a first distribution device, in a case of receiving data to which a service providing device that provides a service to a user or a calculation device having at least a communication function and an arithmetic processing function is set as a transmission destination, selecting, as a distribution destination, a single or a plurality of line switching networks or a single or a plurality of packet switching networks on a basis of distribution policy information, and transmitting the received data to the selected switching network;
• transferring, in a case where the data is received from the first distribution device in the line switching network, the received data through a line generated corresponding to the transmission destination of the data;
• transferring, in a case where the data is received from the first distribution device in the packet switching network, the received data through a route corresponding to the transmission destination of the data among a plurality of routes;
• and
• by a second distribution device, in a case of receiving the data transmitted by the first distribution device from the line switching network or the packet switching network, capturing the received data on a basis of aggregation policy information, and transmitting the captured data to the service providing device or the calculation device corresponding to the transmission destination of the captured data, wherein the aggregation policy information indicates an aggregation policy for (i) time division reception, in which a receiving destination is switched in time, (ii) simultaneous reception, in which data is received from multiple destinations simultaneously, or (iii) selective reception, in which the receiving destination is selectively switched according to priority.
