No formal introduction is required by the protocol 2. One end just starts sending data to the other end. And on top of that, there is no handshake at all.

The TCP connection gets established and you get full advantage of all the features it has to offer. Your browser would use TCP to connect to the port 80 of the server hosting the website. Smaller packet size We save an extra 12 bytes in each packet for the actual payload.Įven increasing the packet size by a single byte could potentially reduce your pps packets per second rate in a fast enough link which would in turn make your link faster and more responsive. Adding IPv4 header on top of it, we get total header size of 28 bytes. As an example, it might not matter much if bunch of frames get dropped in a live camera feed and certainly re-sending them is counter productivehence using UDP to transfer a live stream could make sense.īecause of the limited feature set, UDP header is much smaller. If a program wants to use UDP for its communication, It also has to deal with all the potential network issues that might arise. In other words, while TCP frees the applications from dealing with low level protocol stack and complex underlying issues, UDP passes this responsibility to the applications. Packets might be dropped, get out of order, get duplicated…. The other end of the stream might receive it, might not. In fact a UDP stream can hardly be called a connection at all. It comes with a checksum header for packet integrity but connection reliably as a whole is not guaranteed. So at least 40 bytes in each TCP packet is the header data that comes before the actual payload.
Ivf 2ww no symptoms bfpĪ typical TCP packet has a header size of 20 bytes. It has some very interesting features built-in which makes it very resistant to network packet loss, packet reordering, packet duplication, unintentional packet corruption and even link congestion.Īll those features however come at a price. Transmission Control Protocol is the dominant protocol there is for most daily stuff happening on a network. To understand the pros and cons of each, we first need to have an understanding of them both.
