Node detection method and node detector
First Claim
1. A node detection method for detecting a node connected to a network, the method comprising:
- upon setting an initial address list in advance;
a first step of interpreting a first script related to cycle to decide a detection cycle;
a second step of interpreting a second script used for selecting information to select next information to be acquired, when node detection timing has come;
a third step of gathering the selected information via the network by using a matching protocol;
a fourth step of interpreting the acquired information and storing node information when it is judged that a new node has been detected; and
a fifth step of causing all the nodes that have been detected by the last node detection, to perform the second to fourth steps.

Abstract
A node detection method and a node detector that enable selection of a node detection method in accordance with the structure and operation of a network are realized. A node detection method for detecting a node connected to a network comprises: a first step of interpreting a first script related to cycle to decide a detection cycle; a second step of interpreting a second script used for selecting information to select next information to be acquired, when node detection timing has come; a third step of gathering the selected information via the network by using a matching protocol; a fourth step of interpreting the acquired information and storing node information when it is judged that a new node has been detected; and a fifth step of causing all the nodes that have been detected by the last node detection, to perform the second to fourth steps.

4. A node detector for detecting a node connected to a network, the node detector comprising:
-
a communication unit that performs communication via the network;
a storage unit in which acquired node information, a first script related to cycle and a second script used for selecting next information to be acquired are stored; and
an arithmetic control unit that set an initial address list in advance, interprets the first script to decide a detection cycle, interprets the second script to select next information to be acquired when node detection timing has come, gathers the selected information via the network by using a matching protocol, interprets the acquired information and storing node information to the storage unit when it is judged that a new node has been detected, and causes all the nodes that have been detected by the last node detection, to gather information. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
