Should I Use Tcp Or Udp

It’s a better choice than TCP because of the following:
– UDP is faster. It doesn’t have TCP’s error correction mechanism and, therefore, the sender doesn’t need to wait for an acknowledgment from the receiver before forwarding more data.
– UDP has lower latency and greater responsiveness than TCP. …
– Because UDP is quicker and more responsive, it needs less audio or video pre-fetching and buffering. …

In your case I’d use TCP unless you actually have hands-on experience with fragmenting and re-assembling UDP packets manually, and you’re willing to maintain the overhead introduced in your code (like having a re-assembling buffer and controlling the latency that this implies). Furtherly, you should take the targetted network into consideration.

UDP is less reliable than TCP, but is much simpler. UDP is used for situations where some data loss is acceptable, like live video/audio, or where speed is a critical factor like online gaming. While UDP is similar to TCP in that it’s used to send and receive data online, there are a couple of key differences.

TCP is more reliable, so you may think that TCP is the best option, but there are times when UDP might be preferred. UDP is a great option if you are gaming, streaming or using VoIP services. It may lose a packet or two but it won’t have.

Should I use TCP or UDP for log forwarding? | AT&T

Description. When sending data over the network, reliable delivery is always at the front of the list. when configuring syslog forwarding, this should be an important factor in deciding whether to use TCP or UDP for the service. In most cases you will likely choose TCP for log delivery as the benefits far outweigh the additional overhead.

One unique case where you would want to use UDP instead of TCP is where you are tunneling TCP over another protocol (e.g. tunnels, virtual networks, etc.). If you tunnel TCP over TCP, the congestion controls of each will interfere with each other. Hence one generally prefers to tunnel TCP over UDP (or some other stateless protocol).

People suggest to use TCP in stead of UDP. I can imagine that a heavy load is more likely to have problems with UDP packets coming over in the wrong order, causing the replay-error. TPC packets, I guess, are confirmed packet after packet, in the correct order. If I test with UDP or TCP and scroll through PDF’s, it looks like TCP is always very slow.

Notable is that TCP is reliable and it guarantees delivery of data to the destination device. UDP is a connectionless protocol where there is no establishment of connection before data transmission. Further, there is no overhead related.


Most people say UDP is always better for real-time games than TCP. My understanding is that TCP tries to re-send packets over and over til the other side gets them whereas UDP doesn’t care. Most of the things I’ve read is that UDP is a must for any realtime game and TCP is terrible. But the thing is, most people seem to implement some form of TCP.

TCP for sending information that is sent infrequently, but should be guaranteed to arrive reliably. Such as score updates, a player’s name, or even the on/off state of a light in the game world. When using both TCP and UDP, you should always prefer to send as much as possible over UDP and as little as possible over TCP..

It also helps to use UDP instead of TCP, because routers tend to be better about allowing incoming connections with that (BitTorrent’s uTP protocol gets that feature as a bonus, switching to UDP wasn’t done for specifically that reason).

You will have packet loss with UDP. Sites like use UDP for video streaming because it doesn’t matter if you miss a few frames. uses UDP because it’s faster than TCP because that connection isn’t established and you probably wouldn’t notice missing frames anyway. You want to use TCP because you don’t want packet loss.

TCP vs UDP, Why use UDP for IP Camera’s Connection?

UDP is the right choice for data that require real-time transmission with low overhead and less processing. For real-time video streaming, we should use the UDP protocol because it can deliver smooth video and require less processing. TCP Vs UDP. When connecting security cameras to the NVR via ONVIF protocol, the NVR will use the default TCP/IP protocol,.

In general, UDP is used where possible for carrying the voice (and any video) packets and any other real-time media content, and TCP is used for everything else, such as registration, directory services, connection setup / signalling, presence, firewall/NAT penetration, etc.

If it uses the TCP protocol to send and receive the data then it will connect and bind itself to a TCP port. If it uses the UDP protocol to send and receive data, it.

TCP is used in applications where reliability is more important, such as file transfer, emails, and web browsing. UDP is used in applications where speed is more important such as video conferencing, live streaming, and online gaming.

On PIA, should I use UDP or TCP? : VPN

UDP for games, TCP for reliability. Basically think of it like this, TCP will send something and wait for a response. UDP doesn’t give a shit and will keep sending data. Sorry, I should have mentioned that I know what the difference between the two is, I was just unsure which would be better for a VPN. Alright, thanks.

OpenVPN Over UDP or TCP. Every top VPN provider offers you a choice of using OpenVPN with TCP or UDP. Which of the two you should pick ultimately boils down to speed and reliability, and what’s more important to you. UDP is better for streaming, gaming, and real-time communication (both audio and video).

In the OSI model the two most popular transport protocols are TCP and UDP. For most people today, reliability is critical and TCP is a natural choice for most applications where data is important; for example, everything from web page, to mail, to SSH are TCP.

TCP is one of those protocol, and it can run on top of IP datagrams (as is done typically) or UDP datagrams, in the case of applications like MixApp that don’t want to use the operating system’s.

TCP vs UDP: What is the Difference Between Both Protocols

To be fair, neither one is particularly better than the other. Both TCP and UDP are suitable for different purposes. If speed is of utmost significance to you, then you should use UDP. If data integrity is your main priority, then you should use TCP.

Exactly how they affect each other is quite complicated and relates to how TCP performs reliability and flow control, but fundamentally you should remember that TCP tends to induce packet loss in UDP packets. For more information, read this paper on the subject. Also, it’s pretty complicated to mix UDP and TCP.

It runs on either the TCP or UDP internet protocol. TCP makes sure your packets (data) arrive fully and in order, which can make it slower, while UDP focuses more on speed (but is a bit more chaotic). Here you can find more information about TCP and UDP. Available on all supported Operating Systems with NordVPN. IKEv2.

The IANA assignment for UDP is historical; at the time, nearly every protocol was assigned both the TCP and UDP port numbers, even if it was expected that it would only ever use one. There has been discussion of merging the port number registries, and only ever assigning one port to one protocol from here on.
