In the present invention, a plurality of information collectors are installed in the elements of the communication network, and the information collected from the information collectors is collectively collected at regular intervals for the performance, quality control, and recovery of the high-speed communication network as described above. A management system 8 for monitoring the overall performance and quality of the high speed communication network by comparing the information with information on the operating environment of each equipment stored in the PC 1 is installed at one end of the high speed communication network.

The information collector 7 has a function of collecting RMON information from various equipment installed in a high-speed communication network, that is, communication means 2, DSLAM 3, NAS 4, PMS 6, and the like. The collector 7 communicates with the devices at predetermined preset periods and collects RMON information provided from them.

This section describes RMON.

RMON is established by the RFC1271 standard called the Remote Network Monitoring Management Information Base. It is a MIB that is added to define new managed objects. This standard specifies whether to collect and store data.

In the past, RMON focused on the interface of each network device (router, hub, system, etc.), and thus, it was possible to obtain information such as traffic characteristics and utilization of the LAN environment.

Therefore, in the present invention, in order to reinforce such a function, a remote monitoring device (information collector) is installed in each segment of the LAN to collect the information of the corresponding segment and then transmit the information to the management system 8.

As shown in FIG. 6, the RMON is composed of several groups, which include a statistics group, a history group, an alarm group, a host group, and a top N host ( host top N) group, matrix group, filter group, packet capture group, event group, token ring group, protocol directory group, protocol distribution ( protocol Dist group, address map group, network layer host-nlHost group, network layer matrix-nlMatrix group, application layer host (alHost) group, application layer matrix (alMatrix) ) Group, user history collection (usrHistory) group, and probe configuration group.

The statistics group informs about the number of packets transmitted in one segment, the number of broadcast packets, the number of multicast packets, the number of collisions, the number of packets discarded by the agent, the real-time notification of the distribution of packet lengths, and statistics on five error packets. Providing groups,

The history group is a group that stores and manages periodic statistical data about the values of each management object in the statistics group based on the time interval set by the user for the traffic trend analysis of the communication network.

The alarm group is a group that supports setting the sampling interval of the traffic data and the reference value for issuing an alarm on the traffic condition on the segment monitored by the information collector 7 for the alarm management function.

The host group provides traffic statistics for each host (device) on the network in the form of a table, which contains information about the number of packets sent and received by each device, the number of bytes, the number of broadcast packets, the number of multicast packets and air Records,

The top N host groups sequentially provide statistics on the items (output packets, input packets, output bytes, input bytes, broadcast type output packets, multicast output packets, and output error packets) in the host group table. The network manager arbitrarily selects the desired data items, monitoring time, number of upper devices, and the like and applies them to the host table.

The matrix group monitors the traffic volume and error packets generated between two nodes at the MAC layer level.

A filter group is a group that enhances the ability to filter and view only packets that match a part of a packet or a packet header entering or leaving a specific node.

An event group provides a packet or related information that matches a predefined packet type.

The protocol directory group is the master directory of all protocols that the probe can interpret and contains a protocol directory table with entries for each protocol.

The protocol distribution group manages statistics on the amount of traffic generated by LAN segments for each protocol.

Address map groups match and manage each network address for a specific MAC address, the device connected to the port, and the physical address of the subnet.

The network layer host group manages statistics on I / O traffic volume of hosts based on network layer addresses.

The application layer host group manages statistical information on traffic of an application level protocol of a specific host, and the application layer matrix group manages statistics on the amount of traffic between hosts based on application level addresses.

The various groups as described above are combined to form the overall RMON information, and these RMON information is provided for each device (communication means (2), DSLAM (3), NAS (4), PMS (6) installed in a high-speed communication network. It is provided by the RMON device that is modularly installed in the module.

The RMON devices mounted on the respective equipments provide the information collector 7 with various RMON information stored therein while communicating with the information collectors 7 applied to the present invention at regular intervals.

The information collector 7 transmits various RMON information collected from each device to the management system 8 when the RMON information of the management system 8 installed at one end of the high speed network is requested. The system 8 analyzes various RMON information provided from each information collector 7 to manage the performance and quality of the high speed network.

2 shows an example of RMON information provided from the information collector 7 to the management system 8 and records the connection status of the local user.

According to FIG. 2, the ID inputted by the local user, the session unique number assigned by the NAS 4, the connection start time, the connection end time, the service use time, and the connection termination reason can be easily grasped.

Fig. 3 records the connection status of the NAS 4 manager. By using this RMON information, it is possible to grasp when the NAS 4 manager has connected to the high speed communication network.

4 is information for recording a user currently connected to a high-speed communication network. According to this RMON information, it is possible to determine whether a user using a single IP accesses as a redundant IP.

That is, currently, only one PC 1 is used as one IP, but where several PCs are connected to an internal network, a case where several PCs are used as one IP is frequently generated. By using RMON information such as the high speed network connection status and access time of multiple users, the same IP is duplicated in the same time zone and connected to the high speed network. It is judged to be connected as.

FIG. 5 shows RMON information recorded when a user's connection request is denied. By using this RMON information, it is possible to grasp that the users are not connected to the high-speed network for some reason. As a result, the network can be repaired.

In addition, when using the present invention, when a user accesses a high speed network and receives predetermined data, the user can easily view information such as the reception speed of the data.

That is, when the user accesses the high speed network and downloads data from the PMS, the data transmission status is detected by the RMON device provided in the communication means 2 and stored and managed by the user. Information on the amount of file, etc. can be provided in real time using the RMON function provided in the communication means (2).

As described above, the present invention can manage the high-speed network as a whole by using the RMON function of various communication equipments installed in the high-speed network, so that the high-speed network can be more effectively managed, and the use of multiple IPs of a single IP user. It is possible to additionally implement a function that can detect.

As described above, the present invention uses the RMON function configured in various equipments (communication means, DSLAM, NAS, PMS) installed for smooth data transmission and reception between a user (PC) and a PMS in a high-speed network. The PC) side collects and stores the information on the current state of the devices while measuring the operating environment of the various devices installed in the high speed network, and configures a plurality of information collectors that collect RMON information from the devices on the communication network. At one end of the high speed network, RMON information is collected from the information collectors and compared with the data measured by the user (PC) to install and manage a management system that monitors and monitors the performance and failure of the entire network. S can manage overall performance and standards of a wide range of high speed networks as a whole, and search for multiple IP usage of a single IP user. It can be expected to provide network performance and standard management equipment of high speed network using NMPV RMON.
