Embodiment Construction

[0043] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0044] The invention provides an Ethernet network transmission performance test device, which can complete the test of all network transmission performance parameters at one time by editing a test frame.

[0045] Such as figure 1 As shown, the present invention defines an Ethernet test frame. The test includes source MAC address (6 bytes), destination MAC address (6 bytes), type (2 bytes), IP header (20 bytes), UDP header (8 bytes), test data part ( N bytes) and CRC check (4 bytes). The source MAC address, destination MAC address, source IP address, and destination IP address can all be preset with a fixed value. figure 2 The hardware circuit shown automatically generates dynamic addresses. CRC check by figure 2 The hardware circuit shown is automatically generated.

[0046] The test data part consists of test frame ID (4 bytes), test fr...

Description

technical field [0001] The invention belongs to the field of network communication testing, in particular to an Ethernet network transmission performance testing device. Background technique [0002] Network technology is widely used, and the transmission rate is getting higher and higher. There is a high demand for network communication equipment testing. How to simulate the data generation of the actual network is one of the key technologies of network transmission testing. In the general Ethernet test now, one kind of static data frame is edited separately, and a single parameter test is performed, and the test frames of various manufacturers are not compatible, so they cannot be tested with each other. Contents of the invention [0003] Aiming at the above-mentioned technical problems existing in the prior art, the present invention proposes an Ethernet network transmission performance test device, which can complete the test of all network transmission performance p...
