Abstract
A management device includes a memory and a processor coupled to the memory. The processor executes a process including, searching a network for a node that belongs to a management area to which the management device belongs, and creating management information in which the node searched for at the searching is used as a node that is targeted for management.
Claims5
A management device that manages an overlay network built on a network, wherein
- management devices, belonging to the same domain, function as nodes of the overlay network,
- key information for a predetermined space corresponding to the overlay network is associated with each of the management devices, and
- the management device includes a memory and a processor coupled to the memory, wherein the processor executes a process comprising:
- calculating first key information corresponding to the management device that is a first node of the overlay network;
- acquiring, from a predetermined node in the overlay network, an IP address of a second node corresponding to the a second key information that is determined by the first key information in the predetermined space;
- acquiring, by accessing the second node based on the IP address of the second node, an IP address of a third node corresponding to a third key information that is determined by the first key information in the present space;
- inserting the first key information between the second key information and the third key information;
- and
- updating, based on the IP addresses of the second node and the third node, key information corresponding to a destination node that communicates with the first node in the overlay network, a node name of the destination node, key information corresponding to a routing node that routs communication of the first node with the destination node, and an IP address of the routing node.
A non-transitory computer readable recording medium having stored therein a management program causing a computer, which is a node in an overlay network targeted for management, nodes of the overlay network targeted for management belonging to the same domain, key information for a predetermined space corresponding to the overlay network being associated with each of the nodes, to execute a process comprising:
- calculating first key information corresponding to the management device that is a first node of the overlay network;
- acquiring, from a predetermined node in the overlay network, an IP address of a second node corresponding to the a second key information that is determined by the first key information in the predetermined space;
- acquiring, by accessing the second node based on the IP address of the second node, an IP address of a third node corresponding to a third key information that is determined by the first key information in the present space;
- inserting the first key information between the second key information and the third key information;
- and
- updating, based on the IP addresses of the second node and the third node, key information corresponding to a destination node that communicates with the first node in the overlay network, a node name of the destination node, key information corresponding to a routing node that routs communication of the first node with the destination node, and an IP address of the routing node.
A management method executed by a management device, wherein
- management devices, belonging to the same domain, function as nodes of the overlay network,
- key information for a predetermined space corresponding to the overlay network is associated with each of the management devices, and
- the management device executes the process comprising:
- calculating first key information corresponding to the management device that is a first node of the overlay network;
- acquiring, from a predetermined node in the overlay network, an IP address of a second node corresponding to the a second key information that is determined by the first key information in the predetermined space;
- acquiring, by accessing the second node based on the IP address of the second node, an IP address of a third node corresponding to a third key information that is determined by the first key information in the present space;
- inserting the first key information between the second key information and the third key information;
- and
- updating, based on the IP addresses of the second node and the third node, key information corresponding to a destination node that communicates with the first node in the overlay network, a node name of the destination node, key information corresponding to a routing node that routs communication of the first node with the destination node, and an IP address of the routing node.
