First Claim
1. An information communication system for exchanging a plurality of contents between a plurality of node devices, the information communication system comprising:
- a plurality of internal networks that are connected to an external network, wherein the internal networks comprise;
the plurality of node devices connecting the internal networks; and
a plurality of support devices, which connect the internal networks, and the external network, and which support the node devices connecting the internal networks to acquire contents by relaying between the internal networks and the external network,wherein a plurality of internal overlay networks, which are overlay networks that allow for exchanging of contents between the node devices connecting the internal networks, are constructed for the internal networks,wherein an external overlay network, which is an overlay network that allows for exchanging of contents among the support devices, is constructed on the external network,wherein node devices connecting a first internal network comprise first acquisition units that acquire contents from a first internal overlay network, wherein the first internal overlay network is one of the plurality of node internal networks, and the first internal overlay network is an access destination of the node devices connecting the first internal network, andwherein if the first acquisition units are unable to acquire the contents from the first internal overlay network, the first acquisition units acquire contents from one of the plurality of support devices in the external overlay network via a first support device, wherein the first support device is one of the plurality of support devices and the first support device connects to the first internal network.

Abstract
An information communication system for exchanging a plurality of contents between a plurality of node devices, includes a plurality of internal networks connected to an external network. The internal networks include: node devices that connects the same internal network; and a support device, which connects the internal network, and which supports acquisition of contents by the node devices. An internal overlay network is constructed for each of the internal networks. An external overlay network is constructed on the external network. Each of the node devices includes a first acquisition unit that acquires contents from a first internal overlay network, which is an access destination of the first acquisition unit. If it is unable to acquire the contents from the first internal overlay network, the first acquisition unit acquires contents from one of the support devices through a first support device, which is a support device connecting the first internal network.
