Abstract

In the present disclosure, a network monitoring system is provided including an IP network monitoring unit ( 610 ) that monitors an IP network to which an IP device is connected; and a non-IP device monitoring unit ( 630 ) that monitors a non-IP device. It is possible to monitor both the IP network and the non-IP device in a system that includes the IP network including the IP device and the non-IP device.

First claim

1 . A network monitoring system comprising:
an IP network monitoring unit that monitors an IP network to which an IP device is connected; and a non-IP device monitoring unit that monitors a non-IP device.

2 . The network monitoring system according to claim 1 , wherein the IP network monitoring unit includes an IP device monitoring unit that monitors the IP device, and an IP switch monitoring unit that monitors an IP switch of the IP network.

3 . The network monitoring system according to claim 1 , wherein the IP network monitoring unit extracts a failure that has occurred in the IP network according to a pre-classified primary isolation cause, and extracts a root cause of the failure based on the extracted primary isolation cause.

4 . The network monitoring system according to claim 3 , wherein the IP network monitoring unit extracts, as the primary isolation cause, at least one of a failure of video information in the IP network, a failure of control information in the IP network, and a failure of synchronization information of the IP device.

5 . The network monitoring system according to claim 3 , wherein the IP network monitoring unit extracts, as the root cause, at least one of a failure of a cable provided in the IP network, a failure of an IP switch in the IP network, and a failure of the IP device.

6 . The network monitoring system according to claim 3 , wherein the IP network monitoring unit extracts a solution to the failure that has occurred in the IP network by performing a detection for the extracted root cause.

7 . The network monitoring system according to claim 1 , wherein the IP network monitoring unit monitors the IP network by visualizing a flow of the IP network on a per-flow basis.

8 . The network monitoring system according to claim 7 , wherein the IP network monitoring unit specifies the flow based on at least one of information collected from a system controller, information set by a user, and information collected from an application for specifying the flow.

9 . The network monitoring system according to claim 8 , wherein the IP network monitoring unit acquires and visualizes, for the specified flow, statistical information of the flow by an SDN function capable of acquiring the statistical information of the flow or a function of performing detailed analysis of packets obtained by a packet capture device.

10 . The network monitoring system according to claim 1 , wherein the non-IP device monitoring unit extracts a failure that has occurred in the non-IP device according to a pre-classified primary isolation cause, and extracts a root cause of the failure based on the extracted primary isolation cause.

11 . The network monitoring system according to claim 10 , wherein the non-IP device monitoring unit extracts a solution to the failure that has occurred in the non-IP device by performing a detection for the extracted root cause.

12 . The network monitoring system according to claim 1 , further comprising:
a system failure automatic detection unit that constantly detects system failures in the IP network; and a designated-failure detection unit that designates an operation of a specific IP device in the IP network to detect a failure.

13 . The network monitoring system according to claim 12 , wherein the system failure automatic detection unit detects at least one of a failure related to a connection port in the IP network, a failure related to a network cable, a failure related to an IP switch in the IP network, a failure related to duplicate IP addresses, a failure related to bandwidth, and a failure related to unknown traffic.

14 . The network monitoring system according to claim 12 , wherein the system failure automatic detection unit or the designated-failure detection unit adds a flow for monitoring when there is a flow that cannot be monitored in the IP network.

15 . The network monitoring system according to claim 14 , wherein the designated-failure detection unit designates the operation by designating from a UI of a failure analysis function, notifying with an API call from a system controller, or identifying by performing analysis using the failure analysis function, and collates whether or not the designated operation is performed with the IP device and the IP network, to detect the failure.

16 . The network monitoring system according to claim 15 , wherein the detection of the failure based on the designated operation is performed by the IP network monitoring unit and the non-IP device monitoring unit.

17 . The network monitoring system according to claim 13 , wherein the system failure automatic detection unit constantly monitors an ARP and an ARP reply and holds a list of IP addresses/MACs in use, and the system failure automatic detection unit detects, when an IP address in use is in use for another device, a failure related to the duplicate IP addresses.

18 . A network monitoring method comprising:
monitoring an IP network to which an IP device is connected; and monitoring a non-IP device.

19 . A network monitoring method for a transmission system in which AV signals are converted into IP packets, the network monitoring method comprising:
monitoring an IP network to which an IP device is connected; and monitoring a non-IP device.

20 . A program for causing a computer to function as:
means for monitoring an IP network to which an IP device is connected; and means for monitoring a non-IP device.
