Abstract
A network monitoring system that monitors a communication network including plural communication apparatuses and includes an obtaining part for obtaining a transmission traffic amount and a reception traffic amount of each port of the plural communication apparatuses, a determining part for determining whether the transmission traffic amount is no less than a first threshold and whether the reception traffic amount is less than a second threshold for each port of the plural communication apparatuses, a storage part for storing connecting path data of the communication network therein, an extracting part for extracting a loop affected path, and an outputting part for outputting data of the loop affected path.
Claims4
A network monitoring system for monitoring a communication network including a plurality of communication apparatuses, the network monitoring system comprising:
- an obtaining part configured to obtain a transmission traffic amount and a reception traffic amount of each port of the plural communication apparatuses;
- a determining part configured to determine whether the transmission traffic amount is no less than a first threshold and whether the reception traffic amount is less than a second threshold for each port of the plural communication apparatuses;
- a storage part configured to store connecting path data of the communication network therein;
- an extracting part configured to extract a loop affected path;
- and
- an outputting part configured to output data of the loop affected path extracted by the extracting part;
- wherein the loop affected path is a connecting path that includes a loop affected candidate port and is connected to a loop path,
- wherein the loop affected candidate port is a port determined as having the transmission traffic amount that is no less than the first threshold and having the reception traffic amount that is less than the second threshold,
- wherein the extracting part is configured to determine whether a communication apparatus including a port constituting the path extracted by the loop affected path extracting part includes the loop affected candidate port, and
- wherein the loop affected path extracted by the loop affected path extracting part is a connecting path including the loop affected candidate port in a case where the loop affected candidate port is included in the communication apparatus.
A path extracting method executed by a network monitoring system for monitoring a communication network including a plurality of communication apparatuses, the method comprising:
- obtaining a transmission traffic amount and a reception traffic amount of each port of the plural communication apparatuses;
- determining whether the transmission traffic amount is no less than a first threshold and whether the reception traffic amount is less than a second threshold for each port of the plural communication apparatuses;
- extracting a loop affected path;
- and
- outputting data of the loop affected path extracted by the extracting of the loop affected path;
- wherein the loop affected path is a connecting path that includes a loop affected candidate port and is connected to the connecting path extracted by the extracting of the loop path,
- wherein the loop affected candidate port is a port determined as having the transmission traffic amount that is no less than the first threshold and having the reception traffic amount that is less than the second threshold,
- wherein the extracting of the loop affected path includes determining whether a communication apparatus including a port constituting the path extracted by the extracting of the loop affected path includes the loop affected candidate port, and
- wherein the loop affected path extracted by the extracting of the loop affected path is a connecting path including the loop affected candidate port in a case where the loop affected candidate port is included in the communication apparatus.
