Re: TCP connection fail

I have a TCP connection that fails after a few minuets of working. It
should continuously deliver video stream. When I watch with a sniffer I see
the following-
1. The Ack packets in the receiver point to a previous received packets
seq counter, instead of to the next packet.
2. The total amount of Ack packets is smaller than the received packets.

Can some help please?

Are you able to run the sniffer at both ends?

TCP is not required to ACK every packet, it can perform ACK combining or
coalescing.

Due to transmit window and RTT, it is expected that the transmitted sequence
number will always be ahead of the ACKed number.
