Node detecting method, node detecting apparatus and node detecting program
First Claim
1. A node detecting method for detecting a node that operates as a device in a computer network, comprising:
- a first transmitting step of transmitting a first detection signal to said node;
a first receiving step of receiving, from said node that received said first detection signal, address information of said node;
a first storing step of storing in a first memory said address information of said node received in said first receiving step;
a second transmitting step of transmitting a second detection signal to said node by using said address information of said node stored in said first memory;
a second receiving step of receiving, from said node that received said second detection signal, classification information of said node in response to said second detection signal;
a judging step of judging a classification of said node based on said classification information of said node received in said second receiving step; and
a second storing step of storing said classification information of said node in a second memory to correspond to said classification of said node.

Abstract
A node detecting method for detecting a node that operates as a device in a computer network, comprises: a first transmitting step of transmitting a first detection signal to the node; a first receiving step of receiving, from the node that received the first detection signal, address information of the node; a first storing step of storing in a first memory the address information of the node received in the first receiving step; a second transmitting step of transmitting a second detection signal to the node by using the address information of the node stored in the first memory; a second receiving step of receiving, from the node that received the second detection signal, classification information of the node in response to the second detection signal; a judging step of judging a classification of the node based on the classification information of the node received in the second receiving step; and a second storing step of storing the classification information of the node in a second memory to correspond to the classification of the node.

14. A node detecting apparatus for detecting a node that operates as a device in a computer network, comprising:
-
a transmitting unit operable to transmit a first detection signal to said node;
a receiving unit operable to receive, from said node that received said first detection signal, address information of said node;
a first memory operable to store said address information of said node received by said receiving unit;
a judging unit operable to transmit a second detection signal to said node based on said address information of said node stored in said first memory, and to judge, in a case where classification information of said node is received from said node in response to said second detection signal, a classification of said node based on said classification information of said node; and
a second memory operable to store said classification information of said node to correspond to said classification of said node.
