python 2.7 Client Server UDP communication, how to overcome packet loss?

I wish this help you Yes, there is a timeout for UDP sockets. See socket.settimeout() in https://docs.python.org/2/library/socket.html and read up on non-blocking sockets in general.
Note that UDP packets can be dropped, duplicated, and/or re-ordered, even if there is no man-in-the-middle attacker. This is because UDP is (by design) an unreliable datagram protocol.

I think the issue was by ths following , XML and JSOn are intended to make application integration simple, but still be human readable.
If you want a protocol tuned to your needs, I suggest you start by determining what information you want to send and how it would look. Document this before you even start implementing it. That way the data sent will suit your needs. (This is more work BTW which is why it is not done more often)

hop of those help? Maybe the key is in the BufferedReader. You're in a loop, and constantly create a BufferedReader to check if something has been sent from the server. Once data is detected, you start processing it, but data keeps coming, and is buffered in the BufferedReader. After processing the initially detected data, you create again a BufferedReader but, what happens with all the data that was already buffered in the BufferedReader created before? Maybe it's lost.
Could you try creating the BufferedReader outside the loop?

it helps some times There's probably no packet loss. TCP just doesn't send packets like how you expect. It sends a stream - like a file. A file isn't made of packets, it's made of bytes. TCP emulates this behavior. So when you send two "packets" the TCP layer (either your TCP library, or the OS or your router or your ISP) may combine them into one TCP packet or break them into multiple TCP packets.
To really know if there's packet loss you have to check the total size of received data vs the total size of sent data.

hope this fix your issue Since client has reset the connection, meaning the old session between client and server has been closed. In this case, it's impossible for server to send response back to the client within closed session.
Server can only send back response for an alive connection, which means the reset connection.

seems to work fine First of all there is no such thing as packet loss in TCP/IP. This protocol was designed to reliably send a stream of bytes in correct order. So the problem must be with your application or the other side.
I am not really in a mood to analyze this whole arraycopy() madness (C anyone?), but why aren't you just sending the whole rbuffer in one go through BufferedOutputStream?
