[0060] In the first step, the data receiving and digital signal processing equipment judges the continuity of the input data packets of two or more 10 Gigabit Ethernet ports through a program: if it is detected that a 10 Gigabit Ethernet port does not have stable and continuous data input within a period of time , then it is determined that the 10 Gigabit network port is faulty, the status is marked and reported, and the 10 Gigabit network port is switched. On the contrary, it is judged that the first step is normal, and the next step is judged; if the 10 Gigabit network port is normal, the program goes to the second step.

[0061] In the second step, the data receiving and digital signal processing equipment determines the VLAN (Virtual Local Area Network) number in the input data packet through the program: if no VLAN number that meets the expectations is detected, it is determined that the 10 Gigabit network port VLAN service Data is interrupted and status is reported. If ...

[0068] The implementation manner of fault location and switching state jumping according to the first aspect of the present invention ( Image 6 )as follows:

[0069] (1) The device starts running, and the programmable digital integrated circuit in the device loads the program and the coprocessor loads the control program, and executes step (2).

[0070] (2) Detect the data packets input by two or more 10 Gigabit network ports within Δt. If the count value of the input data packets of the main 10 Gigabit network port reaches the standard, perform step (3); If the input data packet count value of the port is not up to the standard, but the input data packet count value of the standby 10 Gigabit Ethernet port is up to the standard, go to step (4). If the value is not up to standard, go to step (9).

[0071] (3) Assuming that there are data packets with two VLAN numbers, one active and one standby, in both the active and standby 10 Gigabit Ethernet ports, first detect the activ...

[0081] Based on a high-performance simulation workstation or high-performance computer, use the functional simulation software of programmable digital integrated circuits to perform functional simulation verification. The schematic diagram of the simulation verification platform of the programmable digital integrated circuit is as follows Figure 7 shown. The test method is:

[0082] (a) In a high-performance simulation workstation or high-performance computer, through the function simulation software of the programmable digital integrated circuit, generate a piece of data that simulates the 10G network data packet, which is used to simulate the 10G data received by the device in the simulation system. network port data.

[0083] (b) Input the simulated data into the digital logic module corresponding to the intelligent fault location and fast switching function of the programmable digital integrated circuit to be tested through the function simulation software of the progra...

Description

technical field [0001] The invention belongs to the technical field of communication transmission, and in particular relates to a method and device for switching a 10 Gigabit network data transmission link in a fault state. Background technique [0002] In a general wired communication system, different devices in the system are deployed in different places according to their different functions. Because the places where the devices are located are far apart, in the traditional analog wired communication system, the signal transmission method through the analog cable will cause a large energy loss. Therefore, in the digital wired communication system, the optical fiber digital 10 Gigabit network is selected as the transmission medium, and the 10 Gigabit network data link is built, which can realize the low-latency, loss-free and fast interaction of large data volumes. [0003] Based on the above background, each device in the communication system exchanges data through the ...
