TCP et UDP sont les deux protocoles principaux de la couche transport. Lors de la configuration d'un routeur ou d'une box internet, il n'est pas rare d'avoir à choisir entre les ports TCP et les
As a result, when there's high ping or low quality line during the OpenVPN login, video/audio conversations when connected to the VPN through a TCP port, 2 Mar 2020 For example, a VPN service can use up to four different ports. Some firewalls allow selective configuration of UDP or TCP ports with the same 13 Mar 2020 Here's how TCP and UDP offer in terms of speed and reliability. device did not understand or agreed on, the information will end in a pitfall. FastestVPN features OpenVPN protocol and gives you the option to choose OpenVPN: Slow external (via Internet) connection via VPN (UDP and TCP / with via VPN tunnel (over LTE 300MBit or another stationary Internet connection StealthVPN is very stable and it can work with both UDP and TCP modes. from your computer is routed through Astrill VPN, so there are no IP or DNS leaks. OpenVPN over UDP, or User Datagram Protocol, is usually faster than TCP because it lacks the error correction feature. Web technologies that depend on real-

27 Nov 2017 UDP. Faster Speed – UDP VPN service offers significantly greater speeds than TCP. For this reason it is the preferred protocol when streaming 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 Why UDP Is Better for Streaming. Without a doubt, UDP is the recommended protocol to use for video and audio streaming. It's a better choice than TCP because
To understand UDP vs. TCP, you will have to understand their underlying IP protocol. Every device that is connected to the internet has a unique address, referred to as an IP address. An IP address consists of numbers and decimals, enabling devices connected to the internet to find other devices to send and receive data.
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).
