Through the use of this standard protocol ‘under security considerations’, any user on any network can access any server on any other network on the Internet. The Internet service provider (I SP) completes the entry into the Internet. I SP operates a network connected to each other at a network proximity point (N AP). A representative network includes communication connections and routing devices known as routers. A router contains a table that correlates addresses with target information

C: \ Program Files \ patent \ FCP-9228.ptd Page 7 497037 V. Description of Invention (3). 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,

C: \ Program Fi1es \ patent \ FCP-9228.ptd Page 8 497037 V. 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

In short, the present invention is applicable to an Internet service provider (IsP) or a group of Internet service providers that are not convenient for an Internet service provider (ISP), or a high-capacity Internet exchange point. Through a flexible hybrid ground-artificial satellite Internet communication system and method, a low-cost and high-performance proximity method is provided. The novel hybrid addition system of the present invention uses at least one artificial satellite, and preferably uses multiple artificial satellites, such as an on-stellation of satellites. A basic embodiment of the present invention includes a hybrid artificial satellite-ground Internet communication system and method that provides a large number of connections between an Internet service provider (ISP) and remote user addresses, wherein the remote user The address generation generates a request for the information provided by the ISP. A representative system includes: a first gateway for processing the request for the message generated at the remote user address, and routing the request A second gateway for processing a request item for a message routed by the first gateway to route the request item to the message supply end; and one or more artificial satellites for The requested message provided by the ISP is transmitted to the remote user address. A representative method includes the following steps: For messages at remote user addresses

Generating a request; processing the request for the message to route the message to the message provider; and transmitting the request message for the IP to the remote user address via one or more artificial satellites. I In the embodiment of the present invention, a request for information routed by a terrestrial communication connection is included, wherein the connection includes the Internet. For the message

C: \ Program Fi1es \ patent \ FCP-9228.ptd Page 12 497037 V. 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

C: \ Program Fi1es \ patent \ FCP-9228.ptd Page 13 497037 5. 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. For the purposes of this description, a shared intranet is an ISP. Its function is different from the commonly used commercial ISP, and it can be enhanced in the same way through its use. Many shared systems include their own satellite dish antennas. For example, in one embodiment,

Description of the invention (ίο) The present invention can be used to transmit p VC to a common dish antenna to provide a "rooftop to rooftop) system. P 0 P 1 0 includes a data frame relay switch 1 0 1, a router array 1 0 3 ′, a multiplexer 1 0 5, and a test server 1 7. The test server 1 0 7 monitors the arrival time of a data packet at the correct destination. As shown in the figure, some USISPs can be directly connected to the router array 103, while other USISPs are connected to P 0 p 1 0 via the data frame relay switch 1 0 1. High-link ground connection provided to the Internet by U S I SP. Some routers in array 103 are dedicated to a specific E I SP, while others are shared by e I SP. The router management can be performed by a U S I SP that acts together with E I S P ′ or a satellite proximity service provider. The data frame relay switch also transfers data from E 丨 SP to us 丨 sp, and to Rudar an SCPC (single channel per carrier) channel, or an international ground lease connection terminated at p0pi (). The device 2 includes a data frame relay switch 1 2 3, a row of satellite modems 1 2 5 and a transmitter 1 2 7 connected to a European antenna 14. The data frame relay switch 1 2 3 includes a virtual circuit mechanism 125. The virtual circuit mechanism 125 may further include an asynchronous transfer mode (ATM) switch. The device 12 is linked to the satellite broadcasting channel and also receives the S C P C channel from the E I SP address. Connect p 〇 European high-speed link device 12 via high-speed ground connection. EISP POPs 22 and 24 show the types of pops considered in the present invention. In particular, P0P22 is a station that receives the data string broadcasted by Europe, and the "P 0 P 2 4" shown as "transmits and receives a station". This station can upload data to Europe and receive data. . P0P22 is a & in network 26, and

497037 V. 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. The two main services in the European Internet Proximity System are classified as < mixed services are classified as mixed services and two-way satellite services. Mixed service

C: \ Program Files \ patent \ FCP-9228.ptd Page 16 497037 V. 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. All from Europe

After the BGP time expires, among the people. In the case of "Sheng Xun Ran", the data may return to the ground circuit. The request packet generated by user c on the network contains 1 ρ source address, user and I ρ destination address. G: The necessary information for the two daggers. In this example, the USLS of the server network is at a different network than the US Internet / REQ via which provides proximity. The EISP network is dedicated to EISp's US Gateway Router 221 (ERTR). The router 2 2 1 maintains B G p with a central link of the Internet traffic, and constructs a router 103 at the satellite supply end. ERTR22 makes routing decisions for the received distance information based on Network Number Checker® Xuanyi and BGP routes. Ertr has also reported the bg P router network number as part of E I SP. Part of the target address provided in the REQ, ERTR 221 routes the REQ across the ocean, 20b, where the satellite gateway POP 10 receives the signal. The routing state 10 3 routes R E Q to a router (URTR) 161 via a data frame repeater p v c on a DS-3 connection 30. This synergistic Eisp URTR 161 routes the REQ based on the target address to the target server. This REq is transmitted to the cooperating E I S P router u in Nap 1 8 and then to the router c of the third guest PEISP via the n ap traffic handle 18 a. Use BGApP, T and C to exchange reachability and distance information. It is then routed via the network JR E Q of the third client E 丨 s p until it reaches the third client β EISP190 which is connected to the server. The router then sends the REq to the server. The server

C: \ Program Files \ patent \ FCP-9228.ptd

497037 5. 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

Page 19 497037 V. 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. In this form, _ ′ E I S P 2 2 obtains a US Internet connection via a two-way artificial satellite circuit. Other types of links to the United States can be used to change a European link

C: \ Program Files \ patent \ FCP-9228.ptd Page 20 497037 V. Description of the invention (16) It should be known 'but generally EISP will use this link for European Internet services: data flow in this configuration It is also similar to a mixed link, as shown in Figure 2. In the configuration of Figure 4, fREQ is transmitted from the user to the ERTR221 at EISP POP22 via the EISp network. The ERTR221 is configured to maintain the BGp time period of 0RTR1 at the artificial satellite gateway ρ〇ρι〇 and from each of the maintained Internet links to receive complete Internet routing table information. Based on the IP address, the RETR221 routes REq to the satellite modem 2 2 6 at P 3 2 P 3 2. The artificial satellite link from Europe to the United States is located on a dedicated sc p c channel. Basically set Cr to make the rate the same as the modem data rate. The REQ is connected via a satellite and reaches a dedicated modem in modem row 1 2 5 and a dedicated port is separated at device 12 at F R s 1 2 3. Via the high-speed ground connection 1 1 the separate data frame repeater PVC is transmitted to 〇RTR103 which is popped up everywhere. OTRR 103 then transmits the REQ on a terrestrial connection 30 to the URTR 163 at usiSP16a. FIG. 5 shows another embodiment of the present invention. The present invention can be applied to a large number of private users such as multinational companies. This satellite proximity service provides a user at a remote location of 70, which allows it to access the company's mainframe server 805 and the proximity of the Internet, as indicated by the server 800 !. This service routes the REQ from the remote client c to the target server 805 (such as the company headquarters in the United States), the server 801 on the US Internet, and the server on the European Internet. Good device 90 1. A proxy server is used, and the REQ from user C is routed on a channel or channels of a satellite 6Q. A local proxy server is provided at POP50. The proxy server determines if the information is routed correctly, and

C: \ Program Files \ patent \ FCP-9228.ptd Page 21 497037 V. Description of the invention (17) It also provides protocol isolation and local fast buffer access function. The proxy server provides an address to route packets on the satellite to the remote address 70. Agreements are also provided to improve the performance of large plastic file transfers. A remote address V S A T (Very Small Slotted Terminal) 7 2 processes a multi-packet data string generated at P 0 P 50, which contains multiple PVCs. This service supports the application of the proxy, which redirects the local model to the appropriate action server (8 0 1, 8 0 5 or 9 0 1), and other remote routers by the proxy server 7 3 routing applications. The data flow in this embodiment is similar to the data flow in the embodiments of FIGS. 1 to 4. Weilv also uses a ground circuit. In this embodiment, the requested path is routed through the Internet in the United States and Europe. This embodiment assumes that the user is also connected to the Internet in Europe. The block diagram in FIG. 6 shows the detailed structure of the present invention and includes the components of each device shown in FIGS. 1 to 5. The ground connection 11 includes DLCI 1 25 and a DS3 pipeline 128. DLCI 124-1, ..., N convert IP packets to PVC 13 0-1, ..., N, respectively. Switching mechanism 12 for transmitting PVC from router 103 in POP 10. The D L C I router function can be distributed between the mixed network service provider 10 and the router with a large capacity I SP. The response packet from the large ISP is broadcast by DLCI128 with higher stopping priority, and it is best to broadcast to the satellite link on the satellite. In a distributed environment, or if the router is only contained in E I SP, the router's routing table is integrated into the hybrid Internet according to instructions from the hybrid network service provider. The required test results will be incorporated into P0P10 in the future. Li gongli
