Device for assessing current status, method for assessing current status, and program for assessing current status

Abstract

In a current state ascertainment device (10), a collection unit (15a) collects flow data, which represents a state of communication matching a predetermined filter, at predetermined time intervals. A specification unit (15b) calculates a path of the collected flow data, specifies a router on the path and input and output interfaces for the router, and stores the specified router and input and output interfaces in a user information DB (14b) of a storage unit (14). An extraction unit (15c) extracts, from the user information DB (14b), a router on a path of flow data matching a predetermined filter and input and output interfaces for the router.

Claims

1. A collection unit that collects flow data representing the state of communication that matches a predetermined filter at predetermined time intervals, An identification unit calculates the path of the collected flow data, identifies routers on the path and input and output interfaces to those routers, and stores the identified routers, input interfaces, and output interfaces in a storage unit. An extraction unit extracts from the storage unit routers on the path of flow data that match the predetermined filter, and input and output interfaces to said routers, A device for understanding the current situation, characterized by having the following features.

2. The collection unit collects flow data that matches each filter for each of the multiple filters. The identification unit identifies the router, the input interface, and the output interface for each of the plurality of filters and stores them in the storage unit. The extraction unit extracts the router, the input interface, and the output interface corresponding to the selected filter from the plurality of filters from the storage unit. The current situation assessment device according to feature 1.

3. The current status assessment device according to claim 2, characterized in that each of the plurality of filters is a filter corresponding to a predetermined particle size.

4. A method for assessing the current situation that is performed by a device for assessing the current situation, The current status monitoring device has a storage unit. A collection process that collects flow data representing the state of communication that matches a predetermined filter at predetermined time intervals, A process of determining the path of the collected flow data, identifying routers on the path and input and output interfaces to those routers, and storing the identified routers, input interfaces, and output interfaces in the storage unit, Extraction step of extracting from the storage unit routers on the path of flow data that match the predetermined filter, and input and output interfaces to said routers, A method for understanding the current situation, characterized by including the following.

5. A collection step of collecting flow data representing the state of communication that matches a predetermined filter at predetermined time intervals, The steps include: calculating the path of the collected flow data, identifying routers on the path and their input and output interfaces, and storing the identified routers, input interfaces, and output interfaces in a storage unit; Extraction step of extracting from the storage unit routers on the path of flow data that match the predetermined filter, and input and output interfaces to said routers, A program to assess the current situation and instruct a computer to execute a command.
