Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a router reliable transmission control method and system. Background Art

[0002] At present, with the development of communication and network technology, various user terminal devices need to exchange and reliably transmit data with radio stations and communication terminals in wireless networks, which requires both secure transmission and flexible switching. When transmitting large amounts of data, controlling devices to transmit evenly on different paths and interfaces will enhance the transmission efficiency of the communication system. Communication equipment will enhance the security of the communication system by checking the routing table to match the network to ensure information transmission between trusted users with fixed IP addresses.

[0003] Commonly used devices for controlling data transmission include switches, communication controllers, and routers. Switches are mainly used to connect devices within a local area network. The connected network segments still belong to the same broadcast domain. Broadcast data packets will propagate on all network segments connected to the switch, which may cause communication congestion and security vulnerabilities in some cases. The communication controller establishes a communication session between the terminal and the network node, manages data communication on the communication link and controls data flow, and provides buffering, error detection and correction, routing, etc. The communication controller is actually a computer with a bus, memory, and central processing unit inside, as well as an adapter connected to the host channel and an interface component connected to the group controller. It requires more hardware and complex software protocols, and is more expensive. A router is a network device that can forward and route data between different networks. In a router, the WAN port is the interface for the router to connect to the wide area network. It is usually used to connect to broadband access devices provided by Internet providers (ISPs), while the LAN port is the interface for the router to connect to the local area network. It is usually used to connect to devices within the local area network, such as computers, mobile phones, printers, etc. The difference between the two interfaces brings convenient conditions for the flexible control and secure transmission of communication information.

[0004] ZTE Corporation's invention patent "Method for realizing switch port isolation, switch and switching chip" (publication number: CN 101123510A) involves the field of Ethernet switches and discloses a method for realizing switch port isolation. The technology includes the following steps: several ports of the switching chip are respectively set as security ports and isolation ports; all isolation ports of the switching chip are set as link aggregation ports; the traffic balancing mechanism of the link aggregation port is turned off to ensure that the second-layer forwarding is carried out according to the normal mechanism. The patent document realizes good port isolation and enables the switch to have more choices in the use of switching chips. Port isolation can be realized by using low-end chips, saving investment and cost, and improving product practicality and stability. However, the scheme has the following defects: First, this implementation method requires the use of switching chips to realize port isolation, and the switch requires specific chips and software support; Second, the realization of port isolation requires the closure of the traffic balancing mechanism of the link aggregation port, which limits the traffic balancing ability of some ports of the switch to a certain extent, and reduces the ability and efficiency of the switch to perform traffic balancing; Third, in terms of trusted user selection and confirmation of data transmission, the switch scheme does not provide relevant solutions.

[0049] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0050] The present invention starts from the perspective of actual needs and applications, and designs a method for realizing internal and external network interface control by utilizing router interface configuration, including input and output interface control, flow balance control and trusted user control.

[0051] Router networking framework Figure 1 As shown, the router can be selected as the desktop model TL-R489GP-AC or the rack model TL-ER6229GPE-AC according to the actual application. Both have 1 WAN port, 3 LAN / WAN ports, and 5 LAN ports. The LAN port supports POE function. Both routers support static routing and traffic balancing.

[0052] The reliable transmission control flow chart of the router is as follows Figure 2 shown.

[0053] This method comprises the following steps:

[0054] Step 1: Router Setup

[0055] Step 1.1: Set the number of WAN ports.

[0056] like Figure 3 As shown, enter the page, in the interface mode of basic settings, select the number of WAN ports, and after the settings are completed, click "Save".

[0057] Step 1.2: WAN port settings.

[0058] Router products provide three ways to access the WAN: fixed IP address, automatic IP address acquisition, and PPPoE dial-up. Wired broadband generally uses the automatic IP address acquisition connection method.

[0059] like Figure 4 As shown, enter the page, in the WAN settings of the basic settings, select the connection method, and after the settings are completed, click "Save".

[0060] Step 1.3: Terminal rate management

[0061] Make sure the IP traffic statistics function is enabled; otherwise, you will not be able to view the correct uplink and downlink rates.

[0062] like Figure 5 As shown, enter the page and select Terminal Management in Basic Settings.

[0063] like Figure 6 As shown, click the Settings button, select Speed ​​Limit, and set the maximum uplink / downlink rate. After setting, click OK.

[0064] Step 1.4: Traffic balancing.

[0065] like Figure 7 As shown, enter the page, in the WAN settings of the basic settings, select traffic balancing, turn on special application routing, and in the balancing mode, select "connection balancing"; after the settings are completed, click "Save".

[0066] Step 2: Network routing table is formed.

[0067] When you select Automatically obtain an IP address to access the WAN in the WAN port settings, the entire communication network chooses to dynamically learn and update the routing table information through the routing protocol. When you select Fixed IP address to access the WAN in the WAN port settings, the entire communication network chooses to manually configure the router information, directly inputting the IP information and connection relationship to determine the routing table information.

[0068] The routing table formation includes the routing table formation of the router device and the routing table formation of the upper-level network switch device in the network.

[0069] Step 3: Data is transmitted reliably.

[0070] After the network is built, the router is set up, and the network routing table is formed through channel establishment. Then the communication network can perform communication tasks between users.

[0071] The above are basic embodiments of the present invention. The technical solution of the present invention is further described below through two preferred embodiments.

[0072] Example 1

[0073] Data transmission based on router traffic balancing.

[0074] The user computer transmits high-speed data streams to the upper computer. The router traffic balancing design splits the data packets through multiple transmissions and synthesizes the data packets for output at the upper network switch. The data transmission diagram based on router traffic balancing is shown in the figure. Figure 8 shown.

[0075] The data transmission scheme based on router traffic balancing is as follows:

[0076] ①Router settings

[0077] Set the number of router WAN ports to three WAN ports, set the WAN port to automatically obtain an IP address, the maximum upstream rate of terminal rate management is 100kB / s, and the traffic balancing mode is connection balancing.

[0078] ② Network routing table formation

[0079] The channel is established and the entire communication network dynamically learns and updates the routing table information through the routing protocol.

[0080] ③Reliable data transmission

[0081] The user computer sets the target address to the network IP of the upper-level computer, and the data transmission rate is 150kB / s. As a result, the data is transmitted in split streams at the router WAN1 and WAN2 ports, and the upper-level network switch receives and synthesizes data packets at the LAN1 and LAN2 ports respectively, and transmits the 150kB / s data stream at the LAN3 port of the upper-level network switch to the upper-level computer.

[0082] Example 2

[0083] Reliable data transmission based on fixed IP address.

[0084] In a multi-user network or multi-external network, such as when CPE and vehicle-mounted stations access the router via different wireless networks, the router can ensure communication between trusted IP users, and communication packets that cannot match the routing table will be discarded. This solution can ensure the communication security of the router's internal and external networks. The schematic diagram of reliable data transmission based on fixed IP addresses is shown in the figure below. Fig. 9 shown.

[0085] The reliable data transmission scheme based on fixed IP addresses is as follows:

[0086] ①Router settings

[0087] Set the number of router WAN ports to three WAN ports, set the WAN port to a fixed IP address, set the maximum upstream rate of terminal rate management to 100kB / s, and set the traffic balancing mode to connection balancing.

[0088] ② Network routing table formation

[0089] The channel is established and the entire communication network chooses the method of manually configuring router information, directly inputting IP information and connection relationships to determine the routing table information.

[0090] ③Reliable data transmission

[0091] The user computer and CPE and vehicle-mounted station can transmit data to each other. The router will check whether the source IP address of the data is in the routing table and whether the target network matches the routing table. If it matches, it will be forwarded from the corresponding port. If it does not match the routing table, the data packet will be discarded. Under the mutual trust fixed IP address, the user computer can communicate smoothly with the CPE and vehicle-mounted station. This transmission scheme enhances the security of the communication system.

[0092] The present invention utilizes the protocol strategy set by the router to realize port control, traffic balancing control and trusted user control, as well as stable, safe and reliable transmission of communication equipment; the business layer and the transmission layer are processed separately, the WAN port is external and connected to the transmission equipment, and the LAN port is internal and connected to the business terminal equipment, and transmission is performed according to the IP address, thus overcoming the information flooding broadcast of the switch; compared with the switch, it has better security advantages.
