The best mode for carrying out the present invention will be described.
Embodiments of a network improvement consulting method and a network improvement system according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram of a network improvement system used in the embodiment.

  Examples will be described. As shown in FIG. 1, the network improvement system used in this embodiment includes a posting server 21, a VS polar 22, a service center computer 31, a VS reporter 32, a router 33, and the like. The posting server 21 and the VS polar 22 are connected to the agent 11, the server 12, the switching HUB 13, and the router 14 that constitute the customer network 1 via the network 15. The service center computer 31, the VS reporter 32 and the router 33 are connected to the customer network 1 via the network line 4. The network improvement system used in this embodiment is a means for detecting an increase in the bandwidth usage rate of a network, a means for detecting an increase in the usage rate of a server communication port, and an increase in the total amount of packets per switching hub. And a means for detecting an increase in the CPU usage rate per router.

  The posting server 21 receives information from the agent 11 at an interval of, for example, once / one hour, and receives error information when an error occurs in the agent 11. The VS poller 22 is equipped with software that collects information such as network usage, error occurrence, and network device performance information, such as a vital suite (product name), and includes an agent 11, a server 12, a switching HUB 13, and a router 14. Raw data is collected from the network 15 etc. at intervals of 5 minutes. In addition, it is equipped with an aggregator, which is software that processes the information collected by the VS polar 22 into statistical information per hour, and can find bottlenecks from information such as the server 12, switching HUB 13, and router 14. The bottleneck information is sent to the display device 16 via the VS reporter 32. The service center computer 31 is equipped with a VS master, which is software for instructing the VS poller and aggregator. The VS reporter 32 creates a report based on statistical information and the like, and transmits the created report to the display device 16 of the customer network connected to the Internet via the routers 33 and 14. The VS polar 22, the routers 14 and 33, and the service center computer 31 constitute a VPN (Virtual Private Network) in which an Internet address (IP address) is specified between routers, and the Internet can be used as a dedicated line. Become.

  A normal operation in the network improvement system of this embodiment will be described. When an error occurs in the agent 11, error information is sent to the posting server 21. The posting server 21 receives the information of the agent 11, for example, once per hour. The VS polarizer 22 collects raw data from the server 12, switching HUB 13, router 14, etc., for example, once every 5 minutes. Next, the aggregator uses the information of the VS polar 22 and creates statistical information at intervals of, for example, once / hour. According to the created statistical information, for example, whether the network bandwidth usage rate exceeds 30%, or the server communication port usage rate is extremely large compared to the server usage rate, or the total packet amount in the switching hub is switched. It is possible to know the network resource that is the bottleneck by determining that the amount is too much compared with the performance of the hub or the CPU usage rate in the router is too large compared with the performance of the router. The statistical information created by the aggregator is transmitted to and stored in the service center computer 31 via the router 14, the network line 4, and the router 33. The VS reporter 32 uses the statistical information stored in the service center computer 31 to display on the display device 16 of the customer network via the Internet line 4. The administrator of the customer network can obtain network statistical information from the display device 16.

  The network improvement consulting in this embodiment will be described. The service center computer 31 determines from the collected information a resource that is or is likely to cause a bottleneck. As resources, there are a server 12, a switching HUB 13, a router 14, a network 15, and the like. The service center grasps the resource that has become a bottleneck, for example, increases the network bandwidth (from 10M to 100M, 1G, 10G), increases the bandwidth of the server communication port, improves the performance of the switching hub (increases the number of units) (Or performance improvement) and router performance improvement (enhancement or performance improvement). In this way, the customer can be consulted for network system improvement.
