Hello..

Thanks for the reply.I have indeed written a simple program to keep track of
the message count. While sending UDP data to the basestation, i receive some
sort of an acknowledgement from the basestation.I notice this in the
wireshark. Will this affect the performance of the network as in increasing
latency or packet loss? The following is the output from wireshark.
