Abstract: A system for managing a network system including an edge server on which an application is executed and a core network of a mobile network connected to the edge server is constructed. The system sets a parameter value group determined by using a setting template associated with an application requirement suitable for an application requirement of the user in the network system. The setting template includes a template parameter value (a parameter value as a template) for each parameter item related to the network system. The system monitors a status of the network system in which the parameter value group is set, and updates the setting template or determines a value displayed based on the setting template based on a result of the monitoring.

Abstract: A protocol chip writes a request from a host apparatus to a shared memory. One of the plurality of processors reads the request from the host apparatus from the shared memory through an address translation unit and writes a response to the request to the shared memory through the address translation unit. The protocol chip reads the response from the shared memory and sends the response to the host apparatus. In the case where a first processor reboots, the first processor performs a reboot process of a first address translation unit but does not perform the reboot process of the shared memory. A second processor reads a first request addressed to the first processor from the host apparatus through a second address translation unit and writes a first response to the first request to the shared memory through the second address translation unit.

Abstract: A computer system is connected to an infrastructure, a version management system, and an infrastructure management system. The infrastructure provides resources for implementing a service. The version management system manages a version of a manifest file describing settings for building the service. The infrastructure management system generates a command for the infrastructure according to the manifest file, and outputs the generated command to the infrastructure. When the manifest file is updated, the computer system receives a notification including a change ID corresponding to the version of the manifest file from the version management system, and transmits an execution instruction including the change ID for performing a change operation to the infrastructure management system so as to store an operation history of the change operation that is associated with the command and the change ID.
