WebTCP FIN & RST – TCP FIN and RST are 2 ways in which TCP connection may be terminated. While TCP FIN is a pretty softer and graceful way of terminating the TCP connection, TCP RST is pretty straightforward and tends to immediately terminate the connection (TCP RST being less chatty than TCP FIN packet) Related >> TCP/IP Port … Web20 de out. de 2024 · I am going to assume that you are dealing with a TCP/IP packet. You will need to calculate this size yourself. The IP header has a 'Total Length' field that gives you the length of the entire IP packet in bytes.

The average size of the packet would depend on the application. @DrZoo is largely right - a typical packet on the internet is 1476 - 1500 bytes, however bigger or smaller packets are possible. This answer does not take into account when a small amount of data is sent in a packet - for example in a chat session.

WebTCP header structure. TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets).
