Invention Description) 14 Reuse the ATM network equipment on it and connect the Internet 15 through the optical fiber 131 to the ATM packet signal to the The Internet 15 or receives an ATM packet signal from the Internet 15. Because the Kushiro architecture directly uses the optical fiber 131 for packet transmission, although its transmission rate can be as high as 640K bytes (Byte) and down to 1.5 Megabytes (Byte), but because of its hardware architecture, In configuration, it is necessary to set up an ATM network at the end to realize the high-speed transmission service of this network architecture. The installation cost is extremely expensive, so it is not easy to popularize to general network users. (2) Cable modem network architecture: In this kind of network system's connection architecture, please refer to Figure 2 for the client's Ethernet card 20 series and cable modem. modem) 201, and the Ethernet card 20 can use the cable modem 201 to connect a cable system operator (or network system operator or central office) to a node device installed in the community through the cable 21 (Node) 22 connection line 'The node device 22 then uses the optical fiber 23 to connect with the network equipment 24 of the cable TV system supplier, and the network device 24 connects to the Internet 25 through the optical fiber 23 to connect the Ethernet The packet message of the network card 20 is transmitted to the Internet 25, or the packet message transmitted from the Internet 25 is received. In this kind of network architecture, the node equipment 22 set up by the cable TV system operator in the community is mainly used to transmit the high-speed transmission performance of the optical fiber 23 through the existing electricity · 21 line of the cable TV system operator ' It is allocated to 100 ~ 500 clients in the community to increase the network transmission rate of each client. This network architecture is generally only used in communities where cable television systems have been widely used. Because in this kind of network architecture, if the cable TV system operator wants to maintain and manage the node equipment set up in each community, the management packet information and the general data packet information are transmitted through the same optical fiber. Line, for transmission, it is very easy to be invaded by network hackers, causing problems in monitoring and management β (3) Network structure of telephone line (UTP): In the connection structure of this network system, refer to Section 3 As shown in the figure, the Ethernet card 30 on the client side is also equipped with an ADSL communication interface (not shown) and a routing control circuit (not shown).

Description of the invention) Unshielded Twisted Pair (UTP) telephone line 31, and the central office (or (Internet system communications operator) One of the Ethernet networks set up in the community The switch (Switch) 32 is connected to the line. The network switch 32 then uses the optical fiber 33 to connect to the Ethernet device 34 at the central office. The Ethernet device 34 is connected to the Internet 35 through the optical fiber 33. Connect to send the packet message from the Ethernet card 30 to the Internet 35 or receive the packet message from the Internet 35. In this kind of network architecture, the network switch 32 set up by the central office in the community is also used to allocate the high-speed transmission efficiency of the optical fiber 33 to a certain number in the community through the existing telephone 31 line. Client to increase the network transmission rate of each client. This is the most widely used network architecture in various communities today. In this kind of network architecture, because the network switches installed in each community are quite far from the central office, maintenance and management cannot be performed at any time nearby, and the use of the network for online maintenance management is limited by General network management systems use the Simple Network Management Protocol (SNMP) simple network management protocol. The central office cannot perform real-time online maintenance and management of each network switch, and must rely on maintenance personnel to each network. The maintenance and management of the installation location of the road switch caused many blind spots and problems in management, and significantly increased the cost of maintenance and management, and caused many negative effects on the quality of network transmission services. Summary of the Invention: In view of the many deficiencies and problems in the aforementioned network architecture, the inventor has developed a management system and device for a community Ethernet switch. The present invention can be borrowed from an Ethernet switch An additional network management control circuit is added on the top to make it difficult for general data packets between each client and the central office to send and receive packets through the Ethernet switch, and the central office monitors each of the network switches. And management of the management packet information, the network management control circuit is used to transmit through another independent line. An object of the present invention is to use the network management control circuit to receive a network management packet from a central office through an independent line, and through the installed SNMP protocol, according to these networks-4 -This paper size applies Chinese National Standard (CNS) A4 specification (21〇) < 297 mm) (Please read the notes on the back before filling this page) · IIIIIII «ΙΙΙΙΙΙΙΙ — belongs to 511354 Α7 Β7 V.

Matters before filling out this page) Detailed description: The present invention is mainly directed to the foregoing It is most widely used in the network architecture of telephone lines (UTP) in various communities. The problem that the central office cannot perform real-time online maintenance and management of each network switch has invented a community Ethernet network switch management. The system and its device, through the present invention, can provide the traditional network architecture with a real-time online maintenance management system for each network switch by the central office. system. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, the network management applications currently used on the network are generally simple network management protocols using SNMP (Simple Network Management Protocol, hereinafter referred to as SNMP) 'The SNMP The protocol is a communication protocol based on the seventh-layer transport layer under the OSI mode (Open System Interconnection Model). The SNMP protocol is used to collect management information from network devices (such as device characteristics, packet traffic, and errors, etc. ), Such management information is collected by the network device and recorded in a Management Information Base (hereinafter referred to as MIB), and then the network manager uses the SNMP protocol to perform online information from the MIB and other such information. management. However, when the SNMP protocol performs connection between network devices through the UDP (User Datagram Protoco, hereinafter referred to as UDP) protocol of its lower transport layer, the UDP protocol writes connection information to be transmitted In the packet, it is delivered to the underlying IP (Internet Protocol) protocol for packet transmission. Although the UDP protocol can provide a more conscious network information service between network devices, the service it provides is not A non-connection-oriented service, which means that it neither establishes a connection relationship with the other party in advance, nor detects errors that may occur during the transmission process. Therefore, the transmission service provided by the UDP protocol is not reliable The upper layer of the SNMP protocol belongs to a passive network management system, which means that the other party will not proactively provide information without the network manager's inquiry. This feature, in transmitting a large number of Paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) 511354 A7 B7 V. Description of the invention (G) If there is an error in the transmission process of the UDP protocol, it will cause Packet loss, the SNMP does not confirm this agreement and, therefore, can not touch the body and provide real-time management of online services network. (Please read the precautions on the back before filling this page) In addition, in the traditional telephone line (UTP) network architecture, refer to Figure 4, its client 40 uses existing telephones _ 41 It is connected to an Ethernet switch (Switch) 42 set up in the community. The network switch 42 then uses the optical fiber 43 to sequentially connect to the office 44 and the Internet 45 to connect the client A packet message of 40 is sent to the Internet 45, or a packet message received from the Internet 45 is received. Because, in this kind of traditional network architecture, each network interface circuit (I / O port) on the network switch 42 for connecting with each client terminal 40 does not have each output such as a telephone switch. Since the telephone fiber detection mechanism is set on the card, it is impossible to cooperate with the network cable on the hardware to perform real-time monitoring and management of each network interface circuit in the network switch 42. In addition, in this traditional network architecture, different client terminals 40 are connected to the central office 44 through each of the network switches 42 and the related optical fiber _ 43 'for packet information transmission'. 44 still monitors and manages each of the network switches 42 through the same path. Bayian is easily invaded by network hackers, which will cause problems in monitoring and management.
