Abstract

A system management device includes a storage part for storing at least one of a device configuration of a device and a network configuration of a network to which the device belongs. The device includes a control part configured to, from among devices belonging to a system, determine the device for executing a process on a basis of at least one of the device configuration and the network configuration.

First claim

The invention claimed is:

1. A system management device, comprising:
a processor; and
a memory storing instructions executable by the processor to:
store at least one of a device configuration of a device and a network configuration of a network to which the device belongs;
from among a plurality of devices belonging to a system, determine the device for executing a process based on the at least one of the device configuration and the network configuration; and
receive a first process result from the device requested to execute the process, wherein
the processor is to select the device to be caused to execute a process according to a received request and, based on device reliability corresponding to device performance based on the device configuration of the selected device and indicative of a probability of an occurrence of an error in the selected device and network reliability corresponding to network performance based on the network configuration of the network to which the selected device belongs and indicative of a probability of an occurrence of an error in the network, determine whether to cause another device to execute another process that is a same process as the process to be executed by the selected device, and determine a different device between a case in which the device reliability has a problem and a case in which the network reliability has the problem,
the processor is to, when causing the device having the network reliability corresponding to the network performance that is lower than a predetermined standard to execute the process, cause the another device having a network path different than a network path of the device to execute the another process,
the processor is to, when causing the device having the device reliability corresponding to the device performance that is lower than the predetermined standard to execute the process, based on the network path to the device, determine the another device for executing the another process such that at least part of the network path of the device and at least part of the network path of the another device coincide with each other,
the processor is to, when the first process result is according to a multiplexed process, determine whether to select a process result to be adopted after waiting for a second process result or without waiting for the second process result, depending on whether execution of the multiplexed process results from the network reliability or the device reliability, and select the process result to be adopted according to a result of determining whether to select the process result to be adopted after waiting for the second process result or without waiting for the another second process result,
the processor is to, when the execution of the multiplexed process results from low network reliability, select the process result to be adopted as the first process result without waiting for the second process result,
the processor is to, when the execution of the multiplexed process results from low device reliability, wait for the second process result and compare and check the first process result and the second process result, and select the process result to be adopted as the first process result or the second process result according to a comparison result,
the processor is to, based on information included by an instruction from a client requesting execution of the process, after once determining the device for executing the process, determine to cause the another device to execute the same process,
the instruction from the client includes information indicating a due date for a response according to the process, and
the processor is to determine to, when a time up to the due date becomes a predetermined time, cause the another device having device reliability higher than the device reliability of the device or network reliability higher than the network reliability of the device to execute the same process.

2. The system management device according to claim 1 , wherein the instructions are executable by the processor to further acquire at least one of device status information indicating a status of the device and network status information indicating a status of the network to which the device belongs,
wherein the processor is to determine the device for executing the process based on the at least one of the device configuration and the network configuration and the at least one of the device status information and the network status information.

3. The system management device according to claim 2 , wherein:
the processor is to store the acquired device status information and the acquired network status information, and estimate a tendency of the at least one of the device status information and the network status information; and
the processor is to determine the device for executing the process further based on the tendency as estimated.

4. A system management method executed by a system management device, the method comprising:
acquiring at least one of a device configuration of a device and a network configuration of a network to which the device belongs;
from among a plurality of devices belonging to a system, determining the device for executing a process on a basis of at least one of the acquired device configuration and the acquired network configuration;
receiving a first process result from the device requested to execute the process; selecting the device to be caused to execute a process according to a received request and, based on device reliability corresponding to device performance based on the device configuration of the selected device and indicative of a probability of an occurrence of an error in the selected device and network reliability corresponding to network performance based on the network configuration of the network to which the selected device belongs and indicative of a probability of an occurrence of an error in the network, determining whether to cause another device to execute another process that is a same process as the process to be executed by the selected device, and determing a different device between a case in which the device reliability has a problem and a case in which the network reliability has the problem,
when causing the device having the network reliability corresponding to the network performance that is lower than a predetermined standard to execute the process, causing the another device having a network path different than a network path of the device to execute the another process,
when causing the device having the device reliability corresponding to the device performance that is lower than the predetermined standard to execute the process, based on the network path to the device, determining the another device for executing the another process such that at least part of the network path of the device and at least part of the network path of the another device coincide with each other,
when the first process result is according to a multiplexed process, determining whether to select a process result to be adopted after waiting for a second process result or without waiting for the second process result, depending on whether execution of the multiplexed process results from the network reliability or the device reliability, and selecting the process result to be adopted according to a result of determining whether to select the process result to be adopted after waiting for the second process result or without waiting for the second process result,
when the execution of the multiplexed process results from low network reliability, selecting the process result to be adopted as the first process result without waiting for the second process result,
when the execution of the multiplexed process results from low device reliability, waiting for the second process result and compar
