Topic: Whether will be lost UDP packets if them to send through TCP VPN

Packets go from server A on server B on UDP. There is a task to eliminate loss UDP, without changing the protocol on TCP. If to start up this traffic through VPN the tunnel constructed on TCP, whether losses UDP of packets in this tunnel are possible?

UDP does not guarantee delivery. If want not to lose - fence acknowledgement of delivery of packets over pure UDP... Y> If to start up this traffic through VPN the tunnel constructed on TCP, whether losses UDP of packets in this tunnel are possible? In the tunnel - hardly, but on an output and on an input theoretically - can.

To take a substrate which does control of delivery and  atop UDP. Y> If to start up this traffic through VPN the tunnel constructed on TCP, whether losses UDP of packets in this tunnel are possible? Are possible - not in the tunnel, and to it and after it. But it is necessary to understand in the beginning, what class of the traffic. If it is supposed stable  packets (for example, the synchronous audio-video) or repetitions at nondelivery (since DNS) -  over transport with a delivery warranty for the account of time delays (as TCP) is the roughest diversion against principles IP and is fraught with lock-outs of all flow with delivery old already  the unnecessary.

MD> Announce the reasons of this "task". It can Quite appear, it is necessary what to struggle not with losses of UDP-packages. There is a server which gives video on UDP. We should write down this video. Access to the code of the server is not present. There is an access to system on which this server is installed. It is necessary to get rid somehow of losses that in record frames were not lost. Or  UDP a stack that these losses strongly to minimize.

tcp  it can turn out even worse 1) to write video locally on the same server and to take away then 2) to launch  udp-> udp-restransmission proxy (srt protocol for example) or udp-> hls/http/itd which will give video on tcp that for a software? And under what OS the server?

Unlike a videoplayer, he was able to write down telecasts if in it to thrust the TV-aerial. But if on air there were noises also record on the holder too turned out with these noises.
