Abstract
A communication device including a comparison unit that compares a first identification number of which notification is provided by a packet that sequentially assigns identification numbers to a plurality of nodes in a network, and a second identification number, which is assigned to the communication device. A control unit notifies other nodes of the second identification number and that the identification number of the communication device has not been changed when the first identification number and the second identification number are in non-conformance.
Claims15
A communication device in a network comprising:
- a comparison unit configured to compare a first identification number provided by a packet and a second identification number, wherein the second identification is assigned as an identification number of the communication device;
- and
- a control unit configured to:
- when the first identification number and the second identification number are in non-conformance, notify at least one node that the identification number of the communication device has not been changed;
- and
- when the first identification number and the second identification number are in conformance, change the identification number of the communication device to a third identification number, the third identification number being different from the second identification number.
A network system comprising a plurality of nodes, a wherein at least one of the plurality of nodes comprises:
- a comparison unit configured to compare a first identification number provided by a packet, and a second identification number, wherein the second identification number is assigned to the at least one of the plurality of nodes;
- and
- a control unit configured to:
- notify other nodes of the plurality of nodes that the second identification number has not been changed when the first identification number and the second identification number are in non-conformance;
- and
- when the first identification number and the second identification number are in conformance, change the identification number of the at least one of the plurality of nodes to a third identification number, the third identification number being different from the second identification number.
A method for performing communication in a network, the method comprising:
- comparing a first identification number provided by a packet and a second identification number, wherein the second identification is assigned as an identification number of a first node;
- and
- notifying at least a second node that the identification number of the first node has not been changed when the first identification number and the second identification number are in non-conformance;
- and
- changing the identification number of the first node to a third identification number, the third identification number being different from the second identification number when the first identification number and the second identification number are in conformance.
