Management server, communication system, network management method, and non-transitory computer readable medium storing program

A communication system comprising:

• a plurality of communication apparatuses;
• and
• a management server configured to manage a network composed of the plurality of communication apparatuses,
• wherein the management server comprises:
• at least one memory storing instructions, and
• at least one processor configured to execute the instructions to:
• manage network information indicating a network structure composed of a plurality of nodes, network parameters associated with the plurality of respective nodes in advance, and apparatus identification information that identifies communication apparatuses corresponding to the plurality of respective nodes;
• receive, from a second communication apparatus among the plurality of communication apparatuses, a change notification indicating that a first communication apparatus among the plurality of communication apparatuses corresponding to a first node among the plurality of nodes has been changed, the second communication apparatus corresponding to a second node adjacent to the first node;
• and
• update information regarding the first node in the network information using the change notification.

A network management method comprising:

• managing network information indicating a network structure composed of a plurality of nodes, network parameters associated with the plurality of respective nodes in advance, and apparatus identification information that identifies communication apparatuses corresponding to the plurality of respective nodes;
• receiving, from a second communication apparatus, a change notification indicating that a first communication apparatus corresponding to a first node among the plurality of nodes has been changed, the second communication apparatus corresponding to a second node that is adjacent to the first node;
• and
• updating information regarding the first node in the network information using the change notification.
