android - Measuring packet loss with Java -


i'm developing app analyses quality of internet connection, , part of measuring packet loss.

i thinking of sending packages ip address, how can send messages , check return? i'm guessing need send package prompting reply, can't find example of using either search or google.

or should use existing traffic(how?)?

besides that, how measure round trip time?

as tcp reliable transport, don't see dropped packets. in linux can use ifconfig see how many retransmits incurred. not sure command line tools show on android, need use system tools give information.

btw can estimate packet loss using udp packets.the packets loss rate udp , tcp not same gives idea.
