The display will jam or slowdown and the same can happen with streaming video. Because of TCP packet error correction, if packets are missing or corrupt and get send over and over, this will cause what is known as game lag.
OPENVPN TCP VS UDP DOWNLOAD
It is the most widely used as it is the best way to download files, websites, pictures, music, whatever it may be, you would want to make sure that it’s not missing tiny bits of data, rendering it corrupt and unreadable. TCP is known as a ‘stateful’ protocol because of its automatic error correction. It scans all the incoming data and pieces it together perfectly. If a packet arrives damaged or corrupt, missing some data or what not, it will not acknowledge receiving it, therefore the sending source will keep sending it ensuring that you get all the data packets.īasically, TCP packets have error protection and ensure you don’t constantly get corrupted downloads. If the packet never arrives, no response is sent and the source will send it once more until it gets acknowledged by the receiver. When a TCP packet is sent, the receiving router will send an ACK (Acknowledgement) packet back to the sender to advise that it arrived. This is the most used type of protocol in networking because it is the most reliable and usually the better fit for most online applications. This is where TCP and UDP come into play and how they individually operate. Some of the packets crash and drop and never arrive while others arrive damaged and need to be resent. These little packets are sent off into the world wide web and travel through various network computers to finally arrive to your router, or not. These packets can be in TCP format or UDP and both have important differences how the packets are treated.
OPENVPN TCP VS UDP HOW TO
That is the wrapper’s job, it knows exactly which piece of data it holds and how to fit it back with the others. You can imagine if thousands of pieces of a puzzle need to be put together, the system better have an efficient way of doing so. So, pretty much it slices everything down to tiny amounts of data that can quickly be sent from a Netflix server all the way to your router and computer network card to be downloaded.Įach little packet containing a small part of the large file, have something called a wrapper, which is a tag of information that contains the sender’s IP address (source), the receiver’s IP address (destination) as well as information on exactly where this packet fits in the puzzle.
OPENVPN TCP VS UDP MOVIE
The way it works, is say you have a movie that is 700 Megabytes, to send you that large amount of data over long distance, it will cut that large file into thousands of tiny ‘ packets’ that range from 7 to 65,000 bytes of data. The internet uses a data packet-switching network. So, what we want to quickly convey, is how files and data is sent from say Netflix to your computer. First we will go over a very basic understanding of how data traffic ( network packets) travels over the internet and we will follow up by going over both TCP and UDP to quickly explain how both protocols work, and everything will start making more sense. But, there’s no need to feel intimidated, we will go over both and once you have an explanation of what each one does, you will be able to better utilize it for your future connections.īoth offer very specific strengths and generally speaking, TCP will almost always be used over UDP, however, nowadays, there are plenty of reasons to take advantage of using a UDP connection with your VPN service. The problem is most people have a hard time understanding all this networking jargon. Furthermore any provider that uses the industry standard ‘ OpenVPN’ will have the option to switch between both protocols. Very often with a good VPN service, you will have the option to use TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) mode for your connection.
