Abstract

There is provided a network control device capable of surely distributing a content even when a relay function of one of the nodes contained in a network stops, without affecting the process in nodes below the node and while improving the reliability of the network system itself. When controlling a node N contained in a network system NS including a server S and a plurality of nodes N constituting a plurality of hierarchies and connected to one another, wherein a content is distributed from the server S to the respective nodes N, it is checked whether a content relay function in a node located at the uplink with respect to the node N in the content distribution has stopped. When the stop of the relay function is detected, control is performed so that the consumption speed of the content accumulated in the lower node N in the process executed in the node N is smaller than the consumption speed before the relay function has stopped.

Description

technical field [0001] The present invention relates to the technical field of a network control device, a connection mode control device, a network control method, a connection mode control method, a network control program and a connection mode control program. More specifically, the present invention relates to a network control device for controlling a distribution mode of distribution information distributed from a distribution source in a network system while relaying distribution information step by step in relay units that are connected and constitute a multi-stage hierarchy , the technical field of a connection mode control device, a network control method, a connection mode control method, a network control program, and a connection mode control program. Background technique [0002] In recent years, network systems have been widely used as the speed of Internet lines for homes has increased. In the network system, a network is constructed by connecting home p...
