Use the router protocol to maintain the information that is still on the routing table to make sure it contains accurate information. Information is transmitted between N APs in the form of individual data packets. Each packet contains an embedded source and a destination address for the packet to be routed across the network. A representative Internet transmission contains a small amount of data represented by a request from a user or user, and a large amount of data represented by a response from a server that contains the requested information. The traffic balance indicates that bandwidth on an asymmetric ground connection has actually been wasted. Many Internet users are limited to terrestrial communications with dial-up proximity sound levels, where the bandwidth is limited to 2 8 K b ps and 56 K b ps. Faster data transfer rates can also be used, but are quite expensive. I SP is known to reduce the capacity of telephone modem banks to reduce costs, and to accept more services to increase revenue. This will cause users to be unable to connect to I SP during the rush hour, and users tend to stay here for a long time when they are close to the system, because users are afraid that they will not be able to go back online. Therefore, it leads to more Internet congestion. One situation where unequal data streams flow between requesters and research servers is the use of Internet users called Web traffic in European users. Today, in nominal European countries, 28% of requests on Web are requests for domestic information, while 25% of requests are for messages from other European countries, and the remaining 50% of requests It requires information from other countries in the world, mainly the United States. Most of this type of international traffic is routed through international traffic such as M A T 4 -E a s t, which is actually located near Washington DC. When a user in Europe requests a Web page or file in the United States,

Description of the invention (4) A small amount of data flows to the United States in the form of a request item, and a relatively large data string is structured to the response item of the request item From the United States to Europe. Now, the amount of data transmitted to Europe is 5 times the amount of data transmitted from Europe to the United States. For the needs of the description of the present invention, it is explained that the remote Is P is inconvenient to connect to the Internet. This is because the state of the underlying problem of some terrestrial telecommunications hubs (b a c k b ο n e) is in line with the reason for the explosive growth of Internet traffic. The US I SP in this example is a high-capacity I SP, in which the terrestrial telecommunications hub substructure provides the necessary capacity, connection points, and equivalence for Internet traffic. The system of the present invention will actually end up being used between substructures that have developed quite well. This technique is simply used as described in the present invention. It is necessary to provide a system that can maximize the use of bandwidth, provide asymmetric use between artificial satellites and ground connections, and efficiently process data packets. The concept of asymmetric bandwidth in hybrid communication networks using satellites and terrestrial connections is known. In a well-known conventional technology system, a desktop user device issues an Internet application on the IP network. The user device is connected to an Internet gateway, where the gateway is connected to a server using a technology that provides traffic management and asymmetric routing. Using the return IP address of the user's satellite dish antenna, the user sends a request to a control center via a telephone link. The response φ to the user's request should transmit one of the artificial satellites in a bundle, and the artificial satellite returns the bundled response to the user's dish antenna. The dish antenna will

Description of the invention (8) The request is routed to the IP via one or more artificial satellites. Receive the transmitted message directly at the remote user address. The requested message may include statistically multiplexing the information packet on a permanent virtual circuit (PVC) to maximize the use of bandwidth, where the packet contains the requested message. The requested message is routed to a remote user address via a gateway or other point of presence (P 0 P) address. In a representative embodiment, it is preferable to use an asymmetric mixing circuit to more efficiently handle the asymmetry generated from a low amount of request and a high amount of response. Through an illustrative example, it can be understood that a request item from a user is coupled to one of a group of I SP occurrence points (P 0 P) via a router and a server. The group I S P P 0 P includes a gateway. The gateway couples the I S P group to a ground connection. The ground connection has a reverse end to lightly connect to a high capacity _ I SP. Multiple request items are directed to the high-capacity IS P via a POP on the high-capacity ISP's messaging hub, and a response is provided. Through one or more routers, the response information packets are subjected to a high degree of statistical multiplexing, and fed into a permanent virtual circuit (PVC). In a telecommunication network supply end P 0 P, the switching mechanism adds a commissioned information transmission rate to each P V C. The commissioned information transmission rate includes a guaranteed minimum bandwidth for its associated P V C. The switching mechanism is managed in an unexpected manner using known protocols. Additional bandwidth may be temporarily assigned to a P V C. It also provides P V C burst (bu r s t) capability. The hybrid network supply end P 0 P sends a signal to the uplink of an artificial satellite. The artificial satellite transmits a signal incorporating all transmission | data to each POP in the I SP group. A router coupled to each I SP POP group filters the downloaded satellite signals to direct a response to the corresponding

Request for invention description (9). It can provide multiplexing or broadcasting from the supply end of the mixed network. If any satellite or terrestrial connection is inactive, the communication can be divided into other connections. Management of transmission bandwidth can be performed in the form of a two-way terrestrial or two-way satellite network. This provides redundancy. The features and advantages of the present invention can be further understood from the following description. Please refer to the accompanying drawings when reading. The detailed description of the preferred embodiment is as follows. Although the present invention can be applied to any Internet communication network, the following The system with reference to the interaction between EI SP and US I SP is taken as the preferred embodiment of the present invention. In this example, a small amount of data, such as the control message 4 requested by the agreement, is transmitted from Europe to the United States, while a large amount of data is transmitted from the United States to ® Europe. Today the data flow from the US to Europe is 3 to 5 times the reverse data flow. Figures 1 to 5 are block diagrams of a system in accordance with the present invention architecture showing data flow. FIG. 6 is a block diagram showing a detailed structure of the present invention, and includes components of each device shown in FIGS. 1-5. As shown in FIG. 1, a system according to an embodiment of the present invention includes a route display point (P 0 P) 10 and an uplink / down link P0P12 connected to an artificial satellite antenna 14. The POP10 interfaces multiple USISPs 16a-16c. Each USISP has its own network (networks (a)-(c)). USISP 16a-16c is interconnected via NA P 1 8.

Description of the invention (11) ρ 0 P 2 4 is part of the network 2 8. Transatlantic ground connection 20a and 20b are located between EISP and any USISP (for EISP related to USISP) or to the European supply side (desired for connection to the US Internet) POP10 EISP). Use these cables to connect to receive E I SP for mixed European / terrestrial services. Using B G P, the commonly acting U S I S P will announce to all I S Ps on the Internet that any return packet from E I S P can be directed to the European link for transmission to E I S P. The Internet core router uses this information to route data packets through an optimal route to E I SP. Routing within Europe is performed via a local ground link, and routing through the United States and Europe in the present invention is performed via a European connection. When a connection fails, its B g ρ announces that it will move the data packet away from the European connection again, and lead to another planned route (if any). Under the data connection level, data transmission is performed in the form of a data frame. The separate P V C is multiplexed and managed by F R S. The P V C is multiplexed as a separate action via the router at each end, only the data arrives at the virtual or secondary interface. Strengthen bandwidth guarantee at FRS. The data frame repeater is used as a one-way (one-way) path, and the configuration of the router eliminates the need for connection management (LM). Each PVC that is guaranteed to enter £ 1 has a minimum bandwidth of one information transmission rate (C I R) on a European channel. If this bandwidth is available on this carrier, each p v c can provide additional burst (b u r s t) bandwidth.

Description of the invention (12) A high-speed European channel that carries data from a server (basically located in the United States) to a requester (basically The upper level is in Europe), and the ground circuit from the request side to the server side (Europe to the United States). According to this method, the cost is significantly reduced by removing excess bandwidth that occurs in high-speed duplex connections. Routing applies delay time (1 a t e n c y) and privately required communications to use satellites or ground circuits. For E I SP without transatlantic ground circuits, a two-way satellite service can be used. In this E I SP network, the address is selected as the uplink to support the request side of W e b, protocol verification, and reverse message flow. Each POP can have its own uplink, or in addition, it can be connected to one receiving receiver via a local communication link. As shown in FIG. 1, in a mixed mode, the user (E I S P) _ chooses to terminate the ground connection. The terminating end can be at the satellite carrier 10 (connection 20b), or at the router located by the USISP POP (connection 20a). The terrestrial terminal of the artificial satellite carrier at P 0 P 1 0 allows E I s p users to directly route different types of traffic to reduce costs. For example, certain types of US-to-Europe traffic such as W W W and F T P can be transmitted via lower cost satellite channels, while other types of traffic such as Te n et and D N S can be transmitted via terrestrial channels. Examples of the data flow of different system forms will be described below. Please refer to Figure 2-4 now. An example of a certain form is shown in FIG. 2, in which EISP22 is connected to the satellite supply terminal P 0 P 1 0 through a full-duplex circuit 20 b across the ocean ground, and a unidirectional artificial satellite p VC for Send data from US Internet servers to users in Europe.

Invention description (14) The processor processes the REQ and generates a relay packet (REP). The REP contains the source IP address and the target IP address of the server. The requesting user is connected to E I SP. The R E P is transmitted through the network of the third client, and crosses to the joint EISP at the closest NAP, where the EISP network is peered. In this respect, it is possible that the REP will enter the E I SP network via a NAP (such as MAE-West, Ameritech, Sprint, etc.) different from NAP18, or via a direct private peering link. The joint E I SP network carries the REP to the URTR161 of the EISP POP 16b. URTR161 then routes the REP to ORTRl 03 at the satellite service provider, where the signal is formatted into a standard data frame relay packet and transmitted to a suitable data link connection identifier as PVC (DLCI). Individual DLCLs identify individual PVCs. By maintaining a BGP period with ORTR, the ERTR221 is announced to the E I SP network via a ground circuit connection. During this period, the β g p packet flows from E T R 2 21 to O T R via the ground connection. The opening of BGP placed in ε IS is adjacent to the satellite interface. If the artificial satellite frequency method is used naturally, the B G P period will reach the end time after a predetermined period (about 3 minutes). Once the routing change propagates (approximately i to 10 minutes), all RFs from the US to Europe will flow through the ground connection. Because there is no return path from the satellite channel, applying a filter will update the routing table from ORTRif ERTR22 1. After confirming that as long as the user's transmission rate does not exceed any packets being discarded, FRS 101 guarantees the quality of the service. When the CIR is exceeded, JFRS will transmit all the packets as much as possible. The rate does not exceed the excess information rate compromised by the user's EISP

Description of the Invention (15) (E I R). If the traffic rate exceeds c 丨 R plus E 丨 R, the excess packets will be discarded. FRS10 1 queues REP to transmit REP on the high-speed ground connection 11 between POP10 and the link device 12. At device 12, the REP is demultiplexed and transferred to F R S 1 2 3. Then, based on the DL c for transmission, the RE p data frame is queued on the appropriate data frame relay artificial satellite link, and each ERTR at E 丨 sp P 0 P detects the entire data frame relay artificial satellite broadcast. . However, its data frame relays the packet received by the connection controller and only through the positioning on D L c 丨, where the DLCI defines the specific packet. The ERTR packet 'ertr *' and if the target IP address matches the address of a user network connected to p Q p 'where the ERTR resides within the p oop, the ERTR forwards the RE p Transfer to customer. If there is no match, E R T R # discards the packet. In Fig. 3, a form is shown in which, through the international leased ground connection 20a that has been connected to the E I SP that is not related to the satellite service provider, the E I SP obtains the main Internet connection. In this example, all R E q are transmitted to the router (URTR) 162 of e 16 s p 16c, and REP is sent back to the user on the higher capacity satellite channel. Pvc1P6c and POP10 are connected by a PVC and transmitted via a private ground local loop and a port on FRS101, or via a high-speed international connection link established for E I SP. Moreover, the EISP is obliged to configure and maintain BGP parity. FIG. 4 shows the configuration of a two-way artificial satellite.
