TDA4VM: Ethernet communication issue between TDA4vm and Xavier

Part Number:TDA4VM

tda4vm与xavier以太网通信测试.pdf

The above file is the Ethernet communication test report between TDA4vm and Xavier.

Using the iperf3 test tool to test the performance of the Ethernet communication between TDA4vm, Xavier and computers.

The problems found in the current test are as follows:

1. TDA4vm sends TCP protocol packets to Xavier, and the number of TCP retransmissions is high; on the contrary, xavier sends the same TCP protocol packets to TDA4vm, and the number of TCP retransmissions is 0.

2. TDA4vm sends UDP protocol packets to Xavier with actual bandwidth (1000Mbytes/sec), and the packet loss rate is as high as 80%; on the contrary, xavier sends UDP protocol packets to TDA4vm with actual bandwidth (1000Mbytes/sec), and the packet loss rate is very low .

3. TDA4vm sends UDP protocol packets to xavier. If the guaranteed packet loss rate is 0, the maximum bandwidth is only 7Mbytes/sec; on the contrary, xavier sends UDP protocol packets to TDA4vm. If the guaranteed packet loss rate is 0, the maximum bandwidth is only 520Mbytes /sec.
