摘要： Example implementations described herein are directed to systems and methods for validating and deploying microservices. In an example implementation, a plurality of similarities are calculated between a user environment and multiple pilot environments from application deployment test results. The test results are based on compatibility of catalogs of applications with each of the pilot environments. A list is presented with one or more of the catalogs of applications that are indicated as compatible and similar to the user environment based on the calculated similarities. The user can select catalog from the list that is deployed in the user environment.

摘要： An anomaly detection apparatus for detecting data flow anomalies classes a plurality of data flows on the basis of similarity in time series changes in the data amounts of the data flows; calculates a correlation coefficient at a normal time and a correlation coefficient at a certain timing between at least two data flows belonging to the same class; and determines that at least one of the at least two data flows is anomalous when a difference between the correlation coefficient at the normal time and the correlation coefficient at the certain timing is greater than a predetermined threshold.

摘要： When a path which is a network communication path is calculated, the amount of path calculation is reduced while satisfying the requirement of the path. The network is logically divided into a plurality of calculation domains, and the divided calculation domains are hierarchically managed, and the path attribute of a path within the calculation domain of a lower hierarchical layer is held as a link attribute of an abstract link of a higher hierarchical layer.

摘要： A passage channel is calculated by taking into account a plurality of requirements having different importance degrees. A channel calculation unit (202) of a transport control server (100) calculates a plurality of passage channel candidates with respect to a passage setting request wherein an active passage candidate and a standby passage candidate are paired in the passage channel candidate; and calculates the occurrence number of phenomena that violate a predetermined requirement relating an operation of the active passage and the standby passage, or a value of a network element for determining whether the requirement is violated, with respect to each passage channel candidate. A cost calculation unit (205) calculates the cost of a passage channel from the calculated number of occurrence, network element value, and a predetermined cost calculation coefficient corresponding to the requirement. A GUI control unit (display control unit) 201 displays identification information of the passage channel candidate, the number of occurrences or the network element value, and the cost, as a list on, for example, a management terminal.
