US 2015/0149550 A1 · NETWORK DEVICE AND INFORMATION SHARING SYSTEM

Abstract

In a network system without a server, a network device and a system that can share information in all devices efficiently and surely are provided. CPUs of a plurality of devices connected to a network determine a host device based on device numbers and network strengths of each of the devices. When transmitting share information stored in a memory to the host device, the CPUs of the client devices merge share information transmitted from the other client devices with the share information stored in the memories so as to transmit the merged information to the host device. The CPU of the host device generates share information about all the devices so as to distribute the information to all the client devices. When the share information is changed, the CPU of the host device generates finite difference information with respect to previous share information so as to distribute the information to all the client devices. When the share information is successively changed, the CPU of the host device merges the respective pieces of finite difference information so as to distribute the information to the client devices.

Dependent claims

A network device including a host device and client devices to be connected to the host device and structuring a network system of a hierarchical structure without a server where the host device is at a top, the network device comprising:

a processing unit;
a storage unit;
and
a communication interface,
wherein
in case that a self device is the client device, when the processing unit is to transmit first share information stored in the storage unit to a device in a hierarchy one level up on network plan data of a hierarchical structure whose top is the host device in cases of receiving second share information from a device in a hierarchy one level down on the network plan data via the communication interface, the processing unit merges the received second share information with the first share information so as to generate merged share information, and transmits the generated merged share information to the device in the hierarchy one level up on the network plan data via the communication interface,
in case that the self device is the host device, the processing unit merges all pieces of share information transmitted from the other devices with third share information stored in the storage unit so as to generate network share information, and transmits the generated network share information to the other devices via the communication interface.

An information sharing system of a hierarchical structure whose top is a host device without a server including the host device and client devices to be connected to the host device, the system comprising:

a plurality of network devices, wherein
each of the plurality of network devices includes
a processing unit,
a storage unit, and
a communication interface,
in case that the self device is the client device, when the processing unit is to be transmit first share information stored in the storage unit to a network device in a hierarchy one level up on network plan data of a hierarchal structure whose top is the host device in case of receiving second share information from a device in a hierarchy one level down on the network plan data via the communication interface, the processing unit merges the received second share information with the first share information so as to transmit the merged information to a network device in a hierarchy one level up on the network plan data via the communication interface,
in case that the self device is the host device, the processing unit merges all pieces of share information transmitted from the other network devices with third share information stored in the storage unit so as to generate network share information, and transmits the generated network share information to the other network devices via the communication interface,
in case that the self device is the client device, the processing unit receives the transmitted network share information and stores the information in the storage unit so as to share the identical share information among the plurality of network devices.
