Description of the Invention (2) The local area network is the basis of current office automation. Common local area networks can be divided into three categories according to different access methods: The first type is FDD that uses tokens as the basis for access. I optical fiber network and token ring network (Token Ring), which is characterized by the use of optical fiber as a transmission medium 'and it is a ring network. The second type of local area network is the widely used carrier detection multiple access / collision avoidance (CSMA / CD; Carrier Sense Multiple Access / Col 1 ision Avoidance) Ethernet network. This network is It is an IEEE 802.3 local area network. Depending on the speed, there are differences in χ, 100Base-x, and 100Base- x. The following χ represents the supportable transmission distance or the media. Common Transmission media are twisted pair (υτρ, Up, coaxial cable, optical fiber, etc. This type of network can be connected into a bus or mixed network. Three types of demand have demand priority.

The benefit of $ is in addition to being able to be wired: it can also be avoided. After a certain line is disconnected, it will affect the network node of 4 53 0 6 8 5. Invention Note (3) affects the network node because the hub is connected to the network. The device of the road cable, so it is a device belonging to the physical layer. However, 'A LAN alone cannot connect to the Internet. Today, in the average home or small business, most of the ways to connect to the Internet are by telephone lines. A telephone line usually requires a modem (MODEM; is the abbreviation of MOdulator / DEModulator, commonly known as a modem) to access the Internet. It can convert a computer's digital signal into an analog signal. We can use it to connect to a telephone line. 'Communicating messages and transmitting data with distant computers is the main tool for ordinary home computers to connect to the Internet. According to the equipment connected to the modem, it can be divided into dial-up modem, network modem (UN modem, IS), N modem, and cable modem. ) Four major categories β The first category is our most common model on the market. It must use the telephone line provided by Chunghwa Telecom to connect with the other party by dialing. The second type of data = is mainly used as Network-to-network connection, so this modem has bridge and device capabilities, and it must support protocol rates such as Tcp / Ip, Ethernet, etc. The third modem must be connected via ISDN and other networks. Up to 144 Kbps; the fourth type of modem uses the currently popular cable television (CATV) cable to achieve Internet access rates of tens of Mbps. plus. With the advent of the Internet era, the demand for home networking is increasing. At the same time, Internet access devices have expanded from simple computers to various other devices.

The software in the disused layer is completed in the CPU and the memory. The main function of the network control device is the sharing of resources (telephone lines) on the Ethernet and wireless network. It is realized by bridge and network address translation. The bridge connects the Ethernet and wireless networks to each other at the second layer of the open system interconnection data link layer (AcCess uses the network address translation to interconnect the third layer of the network at the open system, and the layers implement Ethernet and Wireless network access to the Internet. Next, the software data flow diagram of the network control device is introduced by the fifth diagram. As shown in the fifth diagram, starting from the Internet side, the data is on the network 5 〇 In the process, the entity 503 is linked to 502, and the data in entity 503 is connected by electricity 406. Explanation of the invention (12) The telephone line is connected to the modem 504. Network control device. The transmission protocol between modem 504 and IP packet 506 is connected by point-to-point transmission protocol 505. IP packet 506 is connected with network card 508 via 802. 3 protocol 507. Data from modem 5 0 4 out and receive is controlled by network address translation. The flow of this section is described in Figure 8 and Figure 9. As shown in Figure 5, starting from the Ethernet side, the data is on the network. 51 〇 Zhongli linked 511 in entity 512, at this time the data passed 1 £££; It can be transmitted to the modem 5 0 4 to access the Internet or obtain data from the Internet, or it can be transmitted to the wireless network via a bridge. —As shown in Figure 5 7Γ 'From the wireless side, the data is on the network 5 2 The link 5 2 1 is in the body 5 2 2, and then the girl comes out from the & a.

Invention description (14) The actual network protocol addresses of the users, and the port number 704. External address 705 records a network protocol address to which a network control device is assigned. (That is, the actual network protocol address used when the packet was sent). The correspondence shown in this correspondence table can ensure that each packet is correctly transmitted to each user's computer or network tablet. If the user has several computers and a network tablet, the network protocol addresses are 10.0. 0. 2 to 1 0. 0. 6. Each user wants to access b, send and receive emails, or download files. The source address in the network protocol header of the user's request packet, data packet 'connection packet will be changed to one assigned by the network control device. This network protocol address and the corresponding relationship of this connection such as external address 701 'external port number 702, internal address 703' internal port number 704 will be recorded in the network address translation address translation correspondence table. In this way, when the requested data is sent back, the packet is dispatched to each user's computer and network tablet according to the corresponding relationship. Figure 8: Flow chart of a network address translation program for a network control device. As shown in the figure, a packet is first obtained from the interface received from the network at the beginning 801. Then, it is determined whether it is the fourth version of the Internet Protocol (I p v 4) 802: otherwise, the packet is continuously received. Next, determine whether the destination address and source of the network protocol are in the area 803. If it is a local area network, it does not need to be forwarded and returns directly to the detail 1.
