2011年3月16日 · Because both TCP and UDP run over the same network, many businesses are finding that a recent increase in UDP traffic from these real-time applications is hindering the performance of applications using TCP, such as point of sale, accounting, and database systems.

2019年3月6日 · UDP In UDP client is like TCP only but with less reliability and better speed. More or less. Larger messages are fragmented into bite-sized packets by UDP and TCP. TCP guarantees that all packets arrive and are in correct order, otherwise nothing is received. This can take some time and a few retries. UDP doesn't care.

Besides HTTP, it can be used for HTTPS too, thanks to QUIC protocol, as before mentioned. As an example: if you're aiming to block HTTPS traffic on a Linux Router with IPTABLES/Netfilter, considering hosts that are on the LAN side, you cannot rely just on rules for dropping incoming connection with 443 as source port, considering transmission via TCP.

2008年11月27日 · The choice between UDP and TCP should not be based on the type of data (e.g., audio or video) or whether the application starts to play it before the transfer is completed ("streaming"), but whether it is real time. Real time data is (by definition) delay-sensitive, so it is often best sent over RTP/UDP (Real Time Protocol over UDP).

Short and simple differences between Tcp and Udp protocol: 1) Tcp - Transmission control protocol and Udp - User datagram protocol. 2) Tcp is reliable protocol, Where as Udp is a unreliable protocol. 3) Tcp is a stream oriented, where as Udp is a message oriented protocol. 4) Tcp is a slower than Udp.

2013年6月5日 · In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

2015年4月6日 · For TCP sockets it will be SOCK_STREAM and for UDP it will be SOCK_DGRAM (DGRAM - datagram). Finally, we can leave out the protocol argument which sets it to the default value of 0 . For TCP sockets you should have used bind() , listen() and accept() methods for server sockets and connect() or connect_ex() for client sockets.

2020年5月15日 · Both TCP and UDP are built on top of the IP, but the TCP uses different packet structure and at the layer-2 it is not possible to mimic the TCP using UDP packets. Of course, if you have the control on both the source and destination, then it is possible to create a reliable UDP tunnel for the TCP packets.

2013年7月3日 · TCP and UDP both are transport layer protocols, both provides a process to process delivery (client to server), but they are very different from each other in the way they provide their services. the main difference between UDP and TCP is; UDP provides a connection-less service whereas TCP provides connection oriented services.

The reason why I personally asked the question "does WebRTC use TCP or UDP" is to see if it were reliable or not. Point 3 says, Media will use TCP or UDP, but DataChannel will use SCTP, so DataChannel should be reliable, because SCTP is reliable (according to the SCTP RFC). This contradicts point 2., so if someone could clarify great!
