1. A communication system, comprising:
a service providing device configured to provide a service to a user;
a calculation device having at least a communication function and an arithmetic processing function; and
a plurality of distribution devices connected to 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, each of the distribution devices selecting 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 where data to which the service providing device or the calculation device is set as a transmission destination is received, transmitting the received data to the selected switching network, capturing 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 transmitting 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.
