Nov 27, 2008 · 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).
Apr 6, 2015 · 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.
The Dockerfile (not compose) docs also note that TCP is the default throughout for the EXPOSE section and port parameters, so compose doing the same would be consistent. – Jeroen Mostert Commented Feb 4, 2020 at 16:41
Jun 5, 2013 · With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call. But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that ...
Mar 17, 2011 · 7. TCP guarantees (in-order) packet delivery. UDP doesn't. TCP - used for traffic that you need all the data for. i.e HTML, pictures, etc. UDP - used for traffic that doesn't suffer much if a packet is dropped, i.e. video & voice streaming, some data channels of online games, etc. edited Mar 16, 2011 at 19:12.
Sep 23, 2024 · Packet Tracer Simulation – TCP and UDP Communications Objectives. Part 1: Generate Network Traffic in Simulation Mode. Part 2: Examine the Functionality of the TCP and UDP Protocols. Background. This simulation activity is intended to provide a foundation for understanding TCP and UDP in detail.
If you're asking if TCP can be implemented in UDP, the answer is no. First, TCP packets and UDP packets have an incompatible format. Second, TCP and UDP have different protocol numbers (seen in the IP header) which means that TCP traffic destined for a UDP port would not be passed to the correct upper-layer protocol. edited Oct 7, 2021 at 5:46.
Nagle's algorithm is the part of TCP that helps ensure that the sender doesn't overwhelm the receiver of a large stream of data, resulting in congestion and packet loss. If you need the reliable, in-order delivery of TCP, and also the fast response of UDP, and don't need to worry about congestion from sending large streams of data, you can ...
There are other cases where UDP is preferable to TCP. 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.
105. In some applications TCP is faster (better throughput) than UDP. This is the case when doing lots of small writes relative to the MTU size. For example, I read an experiment in which a stream of 300 byte packets was being sent over Ethernet (1500 byte MTU) and TCP was 50% faster than UDP.
