android bandwidth test

Note: The latest project will test the bandwidth between any two nodes in the network. I have found a lot of information and read many articles on csdn. I still have no clue. I couldn't think of a better way. I was depressed and thought about it for a long time. Repost this article to see how it is implemented. ZZ from http://blog.ouc.edu.cn/netdata/ =========================================================

Iperf is a network performance testing tool. Iperf can test TCP and UDP bandwidth quality. The Iperf can measure the maximum TCP bandwidth with multiple parameters and UDP characteristics. Iperf can report bandwidth, delay jitter, and packet loss. Using Iperf, this feature can be used to
