Abstract

A network configuration diagram generate method executed by a computer, the method includes identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates; determining, for each change in a configuration of the predetermined system, a relationship of a communication distance between the plurality of virtual machines by using the location and the communication destination, the configuration indicating a relationship of the plurality of virtual machines; extracting a difference between the relationship of the communication distance before the configuration change and the relationship of the communication distance after the configuration change; and generating a network configuration diagram in which the extracted difference is indicated.

First claim

What is claimed is:

1 . A network configuration diagram generate method executed by a computer, the method comprising:
identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates; determining, for each change in a configuration of the predetermined system, a relationship of a communication distance between the plurality of virtual machines by using the location and the communication destination, the configuration indicating a relationship of the plurality of virtual machines; extracting a difference between the relationship of the communication distance before the configuration change and the relationship of the communication distance after the configuration change; and generating a network configuration diagram in which the extracted difference is indicated.

2 . The network configuration diagram generate method according to claim 1 , wherein the method comprising:
creating a communication cost model indicating a communication distance relationship between the plurality of virtual machines by using the communication destination and the location, extracting a difference between the communication distance relationships before and after the configuration change by comparing a first model that is the communication cost model corresponding to a configuration before a change with a second model that is the communication cost model corresponding to a configuration after the change, and visualizing the difference in association with a visual representation related to the configuration change.

3 . The network configuration diagram generate method according to claim 1 , wherein
the network configuration diagram is indicated by a graph representing the plurality of virtual machines as nodes and communication relationships between the plurality of virtual machines as edges, and the generating process includes:
associating the extracted difference with the edges, and
visualizing the associated edges in the network configuration diagram.

4 . The network configuration diagram generate method according to claim 2 , wherein the method comprising:
defining a communication cost indicating the communication distance relationship between the virtual machines for each positional relationship between the virtual machines in a network configuration, and allocating the communication cost to the communication cost model based on the communication distance relationship between the virtual machines based on each arrangement location of the virtual machine and the definition.

5 . The network configuration diagram generate method according to claim 4 , wherein
the communication cost model is created by storing a communication cost between virtual machines corresponding to a row and a column, in a value of a communication cost matrix indicating combinations between the virtual machines as a symmetric matrix.

6 . A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process comprising:
identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates; determining, for each change in a configuration of the predetermined system, a relationship of a communication distance between the plurality of virtual machines by using the location and the communication destination, the configuration indicating a relationship of the plurality of virtual machines; extracting a difference between the relationship of the communication distance before the configuration change and the relationship of the communication distance after the configuration change; and generating a network configuration diagram in which the extracted difference is indicated.

7 . The non-transitory computer-readable storage medium according to claim 6 , wherein the process comprising:
creating a communication cost model indicating a communication distance relationship between the plurality of virtual machines by using each communication relationship between the plurality of virtual machines and the location, extracting a difference between the communication distance relationships before and after the configuration change by comparing a first model that is the communication cost model corresponding to a configuration before a change with a second model that is the communication cost model corresponding to a configuration after the change, and visualizing the difference in association with a visual representation related to the configuration change.

8 . The non-transitory computer-readable storage medium according to claim 6 , wherein
the network configuration diagram is indicated by a graph representing the plurality of virtual machines as nodes and communication relationships between the plurality of virtual machines as edges, and the generating process includes:
associating the extracted difference with the edges, and
visualizing the associated edges in the network configuration diagram.

9 . The non-transitory computer-readable storage medium according to claim 7 , the process comprising:
defining a communication cost indicating the communication distance relationship between the virtual machines for each positional relationship between the virtual machines in a network configuration, and allocating the communication cost to the communication cost model based on the communication distance relationship between the virtual machines based on each arrangement location of the virtual machine and the definition.

10 . The non-transitory computer-readable storage medium according to claim 9 , wherein
the communication cost model is created by storing a communication cost between virtual machines corresponding to a row and a column, in a value of a communication cost matrix indicating combinations between the virtual machines as a symmetric matrix.
