When it comes to transferring data via VPN, the speed and reliability of the transfer depend primarily on the protocol that you use. There are two that you can choose from – Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).If you've used any good VPN app from providers such as ExpressVPN, CyberGhost or NordVPN as well as many others you'll find both options in the If the VPN uses TCP, then your own TCP connections will use IP packets sent through the VPN, so you end up paying the TCP overhead twice. An UDP-based VPN thus has the potential for slightly better performance. On the other hand, the cryptographic protection of the VPN requires some state management, which may be harder for the VPN implementation when using UDP, hence it is possible … What are the pros/cons with TCP vs UDP? UDP is mainly used for online streaming and downloading. TCP is more reliable but a little slower than UDP and usually used for web browsing.

What are your DNS TCP, UDP, and OpenVPN. OpenVPN, the VPN protocol that the ProtonVPN Windows app and Linux command line tool are built upon, allows you to choose between TCP or UDP for your VPN connection. OpenVPN’s default is to use UDP simply because it is faster. The smart protocol selection feature, available on version 1.9.2 and later of the Windows app, will always attempt to establish a connection 21/07/2020 TCP vs UDP : C’est quoi la différence ? La réponse dépend vraiment de votre propre utilisation et de vos besoins en matière de sécurité.

You may see UDP and TCP related to VPN’s. What do they do, and how will it change how a VPN works. This short guide shows the difference between UDP and TCP. 15/04/2019 When the TCP VPN protocol is used there is "guaranteed delivery." This is due largely in part to a method called "flow control." Flow control determines when data needs to be re-sent and stops the flow of data until previous packets are successfully transferred. 16/09/2018 Those protocols are almost all TCP-only and not UDP. On such networks it's useful to also support TCP connections, even though this is less ideal due to the possibility of the TCP Meltdown phenomenon. But given the choices between something that works reasonably well or not at all, we've chosen to be practical and also support TCP. By default we choose the port TCP 443 which is the same port TCP is more reliable, so you may think that TCP is the best option, but there are times when UDP might be preferred. There is an option within the OpenVPN application that allows selection of a TCP-based connection, however if you find it becomes necessary to use TCP - we recommend using SoftEther or L2TP (L2TP is a TCP-based client offering flawless connection for mobile devices in particular).

UDP VPN Service. Faster Speed – UDP VPN service offers significantly greater speeds than TCP.For this reason it is the preferred protocol when streaming HD videos or downloading torrents/p2p . Preferred – UDP VPN tunnels are the preferred OpenVPN connection method if your network supports it. Lower Reliability – On rare occasions UDP can be less reliable that TCP VPN connections as UDP

You really don't want to have congestion control on your encapsulated connection and the underlying real connection. It actually would be fine for some workloads, but definitely not for streaming.
