Embodiment 1
[0073] like figure 1 As shown, the present invention provides a switch mesh testing system, including: a switch 001 , a testing device 002 , and an optical fiber connection line 003 . The switch 001 further includes switch network ports 0011. In this embodiment, there are eight switch network ports 0011, which are the first switch network port A1, the second switch network port A2, the third switch network port A3, and the fourth switch network port A3. The switch network port A4, the fifth switch network port A5, the sixth switch network port A6, the seventh switch network port A7, and the eighth switch network port A8.
[0075] The test equipment network port 0021 includes the first switch network port A1, the second switch network port A2, the third switch network port A3, the fourth switch network port A4, the fifth switch network port A5, the sixth switch network port A6,...
Embodiment 2
[0127] Based on a switch mesh testing device provided in Embodiment 1, Embodiment 2 of the present invention further provides a switch mesh testing method, which includes the following steps:
[0128] Step 1. The test equipment is powered on and started, and the real-time clock module in the test equipment generates local time.
[0129] Specifically, after the test equipment is powered on and started. The real-time clock module starts from zero seconds at a clock frequency of 100Mhz to generate local time. That is, the local time increases by 10 nanoseconds per clock cycle.
[0130] The local time is represented by 8 bytes of data, in which the upper 4 bytes represent the second value and the lower 4 bytes represent the nanosecond value.
[0131] Step 2: The data analysis module initializes the first parameter register RAM_A, the second parameter register RAM_B, the third parameter register RAM_C, the fourth parameter register RAM_D, and the first parameter register RAM_A, t...

Abstract
The invention discloses a switch mesh testing system and method. The system includes an optical fiber connecting line, and also includes testing equipment. The testing equipment includes a testing module and a plurality of testing equipment network ports, and each testing equipment network port is connected to the testing module. , each test equipment network port is connected to the one-to-one corresponding switch network port through an optical fiber cable. The test module includes a real-time clock module, an Ethernet interface module, a data scheduling module and a data analysis module. The Ethernet interface module includes a message sending module and Message receiving module; the advantages of the present invention lie in: adopting a full mesh testing method in which each port sends test messages to all other ports in a cyclic manner, reflecting the data exchange capability of all ports of the switch, and testing the switch in a real network environment Data forwarding performance.
Description
technical field [0001] The invention relates to the field of intelligent substation switch testing, and more particularly to a switch mesh testing system and method. Background technique [0002] With the transformation of the power grid to digitization and intelligence, it is accompanied by the large-scale use of switches in the secondary system of smart substations. The reliability of switches will directly affect the security and stability of the power grid. [0003] Traditionally, the RFC2544 standard is mostly used to measure the reliability of switches. However, the RFC2544 standard only shows the data forwarding performance of the switch from a single port to a single port, and the data flow in the real network is that any two network ports of the switch have data forwarding. Therefore, this end-to-end test method cannot reflect the full performance of the switch. Port data exchange capability, such as China Patent Authorization Announcement No. CN105610641B, disclos...
