Abstract
A communication apparatus as a node of a communication network comprises a reading device that reads management information representing management status of a dominated node stored in the dominated node connected via the communication network, a writing device that writes identification information for managing the dominated node into the dominated node when the management information does not include identification information of other dominating node, and a management device that manages the dominated node. The communication apparatus is complied with the IEEE1394 Standard and capable of managing the other nodes on the communication network.
Claims21
A communication apparatus as a node of a communication network, comprising:
- a reading device that reads management information representing management status of a dominated node stored in the dominated node connected via the communication network;
- a writing device that writes identification information for managing the dominated node into the dominated node when the management information does not include identification information of other dominating node;
- and
- a management device that manages the dominated node.
A communication apparatus as a node of a communication network, comprising:
- a reading device that reads management information representing management status of a dominated node stored in the dominated node connected via the communication network;
- a requesting device that requests permission to manage the dominated node to other dominating node when the management information includes identification information of the other dominating node;
- and
- a management device that manages the dominated node in accordance with the permission of the other dominating node.
A communication apparatus as a node of a communication network, comprising:
- a reading device that reads management information representing management status of a dominated node stored in the dominated node connected via the communication network;
- a confirming device that confirms whether other dominating node is managing the dominated node or not when the management information includes identification information of the other dominating node;
- and
- a management device that manages the dominated node when the other dominating node is not managing the dominated node.
A communication apparatus forming one dominated node of a communication network, comprising:
- a lower layer that is managed by other node of the communication network and has a communication device that transmits/receives a signal to/from other node connected to the communication network;
- and
- a storage device that stores management information representing a management status of the lower layer.
A communication system, comprising:
- a dominated node comprising a lower layer that is managed by other node of the communication network and has a communication device that transmits/receives a signal to/from other node connected to the communication network, and a storage device that stores management information representing a management status of the lower layer;
- a first dominating node comprising a reading device that reads the management information stored in the dominated node connected via the communication network, a writing device that writes identification information for managing the dominated node into the dominated node when the management information does not include identification information of other dominating node, a management device that manages the dominated node, a request receiving device that receives a management request for managing the dominated node from other dominating node, and a responding device that responds to the other dominating node with permission to manage or rejection of the request in accordance with the received request;
- and
- a second dominating node comprising a reading device that reads the management information stored in the dominated node connected via the communication network, a requesting device that requests permission to manage the dominated node to the first dominating node when the management information includes identification information of the first dominating node, and a management device that manages the dominated node in accordance with the permission of the first dominating node.
A communication method, comprising the steps of:
- (a) reading management information representing management status of a dominated node stored in the dominated node connected via a communication network;
- (b) writing identification information for managing the dominated node into the dominated node when the management information does not include identification information of other dominating node;
- and
- (c) managing the dominated node.
