Description

Technical Field

[0001] This invention belongs to the field of embedded system development technology and relates to a real-time troubleshooting and location method for complex link application scenarios, especially a method for online monitoring of Ethernet dual-redundant three-level transmission links. Background Technology

[0002] With the development of the maritime industry, the networks in communication, control, and navigation have extremely high requirements for reliability and fault response. This places higher demands on the stability, anti-interference, and bandwidth of Ethernet networks. Redundancy design can be an effective means to improve equipment reliability. Traditional solutions have always used Ethernet dual redundancy, which mainly refers to connecting the Ethernet at the device end to different switches, constructing dual network nodes through the switches. The information sending end selects one Ethernet port (primary path) to send information. When that port fails and cannot send information, the other Ethernet port (backup path) automatically takes over and sends information.

[0003] To meet the needs of ship users for dual-redundant Ethernet information, information is sent to different user terminals through a three-level transmission link. To ensure that users at each link terminal use navigation information correctly, an online monitoring three-level dual-redundant Ethernet transmission link is designed to promptly locate any faults in any level of the link.

[0004] A method for online monitoring of dual-redundant three-level Ethernet transmission links can provide a reference for real-time troubleshooting and location in complex link application scenarios. However, a search of existing domestic documents and materials reveals that this method is currently lacking.

[0005] Therefore, this invention proposes a method for online monitoring of Ethernet dual-redundant three-level transmission links. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and propose a method for online monitoring of Ethernet dual-redundant three-level transmission links, which can achieve the functional and performance requirements of Ethernet transmission information reliability.

[0007] The present invention solves its practical problem by adopting the following technical solution:

[0008] A system for online monitoring of a dual-redundant three-level Ethernet transmission link includes: a first network for information transmission and a second network for information transmission, used to realize online monitoring;

[0009] The output of the first network of the information sending end is connected to the first terminal device through a portable switch. This is to ensure that when the first network has a problem, the first terminal device can receive information from the information sending end normally through the second network via the portable switch, ensuring that the first terminal device accurately receives information and serving as a basis for comparing the accuracy and correctness of the information received by the second terminal device.

[0010] The output of the first network of the information sending end is also connected to the first-level gateway isolation switch for first-level information isolation; the first-level gateway isolation switch is also connected to the first-level gateway isolation switch for second-level information isolation.

[0011] The first and second level gateway isolation switches are connected to the user terminal and the second terminal device respectively, to ensure that the second terminal device and the user terminal receive information normally, and to compare the accuracy and correctness of the received information with that of the first terminal device.

[0012] Furthermore, the output terminals of the first-level gateway isolation switch and the first-level gateway isolation switch are also connected to the mirror port recording module to detect whether there is congestion in the gateway isolation device during information transmission, which would prevent information from continuing to be transmitted.

[0013] Furthermore, the output of the second network of the information sending end is connected to the first terminal device through a portable switch, which is used to ensure that when the second network has a problem, the first terminal device can receive the information from the information sending end normally through the first network via the portable switch, ensuring that the first terminal device receives the information accurately, and serving as a basis for comparing the accuracy and correctness of the information received by the second terminal device.

[0014] The output of the second network of the information sending end is also connected to the second-level gateway isolation switch for first-level information isolation; the second-level gateway isolation switch is also connected to the second-level gateway isolation switch for second-level information isolation.

[0015] The second-level gateway isolation switch is connected to the user terminal and the first-level gateway isolation switch. It is used for the second terminal device and the user terminal to receive information normally, and to compare the accuracy and correctness of the received information with that of the first terminal device.

[0016] Furthermore, the output terminals of the second-level gateway isolation switch and the second-level gateway isolation switch are respectively connected to the mirror port recording module, which is used to detect whether there is congestion in the gateway isolation device during information transmission, causing the information to be unable to continue to be transmitted.

[0017] A method for online monitoring of a dual-redundant Tier 3 Ethernet transmission link includes the following steps:

[0018] Step 1: Connect the first network of the information sending end, the second network of the information sending end, and the first terminal device through a portable switch;

[0019] Step 2: Connect the first network of the information sending end, the second-level gateway isolation switch, and the first and second-level gateway isolation switches through the first-level gateway isolation switch, and set up a mirror port on the first-level gateway isolation switch;

[0020] Step 3: Connect the second-level gateway isolation switch, the second terminal device, and the user terminal through the first-level gateway isolation switch, and set up a mirror port on the first-level gateway isolation switch;

[0021] Step 4: Connect the second network of the information sending end and the second-level gateway isolation switch through the second-level gateway isolation switch, and set up a mirror port on the second-level gateway isolation switch;

[0022] Step 5: Configure the mirror port on the second-level gateway isolation switch;

[0023] Step 6: Open the mirror port set on the first terminal device, the mirror port set on the first-level gateway isolation switch, the mirror port set on the first-level gateway isolation switch, the mirror port set on the second-level gateway isolation switch, the mirror port set on the second-level gateway isolation switch, the corresponding monitoring software on the second terminal device and the user end, and start monitoring and recording.

[0024] Advantages and beneficial effects of the present invention:

[0025] 1. This invention proposes a method for online monitoring of a dual-redundant three-level Ethernet transmission link. The system is divided into subsystems with independent processing capabilities that do not interfere with each other. Each subsystem is isolated from network storms, typically using gateway isolation devices to isolate information from outside the system. When users need to transmit processed information across subsystems, a two- or three-level transmission link is used. This invention monitors the second and third levels of the three-level link at the information sending end. Through hardware power-on testing, experimental environment establishment, and experimental verification, the correctness and reliability of the proposed dual-redundant three-level Ethernet transmission link are confirmed, meeting user and design requirements and possessing practical significance.

[0026] 2. This invention connects Network 1 and Network 2 to the first terminal device via a portable switch. The backup link can quickly and seamlessly switch over and automatically take over the data transmission task. In the three-level transmission link of this invention, the information transmission status of each level of the link is recorded and monitored in real time to determine what causes congestion in a certain link, ensuring that data can be transmitted uninterruptedly and smoothly in the three-level transmission link.
