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.

You can find here a very good article about TCP vs. UDP in the context of game development. Additionally, iperf (jperf enhance iperf with a GUI) is a very nice tool for answering your question yourself by measuring. I implemented a benchmark in Python (see this SO question). In average of 10^6 iterations the difference for sending 8 bytes is ...

This is for example used in virtual networking services, where another instance of TCP/IP is typically run over a UDP channel. (Making the channel use a reliable protocol like TCP can actually have disastrous consequences in that case due to resend cascades.) So the term "TCP connection" refers to the application of the TCProtocol.

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.

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.

2013年3月26日 · The reason is due to the use of NAT, and how NAT table entries in a wireless router or a cell providers' router are generally timed out much quicker for UDP vs TCP. Since keeping the same NAT table entry is necessary to be able to reliably receive calls, SIP must periodically send out keep-alives to maintain the NAT table entry.

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.

2016年7月12日 · Remember, independently of their respective socket identifier formats, both TCP and UDP datagrams identify the port number of the sender; i.e., even a connectionless protocol as UDP has to identify the sender of the transmission as Kurose and Ross explain in their pretty good book “Computer Networking - a Top Down Approach”:

2015年9月18日 · I have implemented a small benchmark for socket communication via TCP and UDP in Python. Surprisingly, TCP is almost exactly double as fast as UDP. To avoid routing effects, server and client are running on the same Unix machine, but on different threads. Maybe the code is useful. Here is the server code:

2013年5月29日 · This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client. Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important.
