- ColinWright 9y agoIt's not clear what your question is. Here's a starting point. The Internet runs on packets of data. * IP : Internet Protocol : [0][1] UDP is a simple wrapper around that to include a few extra things such as ports and the like. * UDP : User Datagram Protocol : [2][3] Transmission Control Protocol (TCP) describes how to break a stream into packets and send them over IP, to reassemble them at the other end, and send back acknowledgements to guarantee deliver. It also has mechanisms to help prevent congestion. * TCP : Transmission Control Protocol : [4][5][6] If you read, or at least skim those, then you will be able to ask a proper, well-formulated question. However, the short version: Q: Ask HN: How do TCP/IP packets work? A: Very well, thank you. ---- [0] https://en.wikipedia.org/wiki/Internet_Protocol https://en.wikipedia.org/wiki/Internet_Protocol [1] https://tools.ietf.org/html/rfc791 https://tools.ietf.org/html/rfc791 [2] https://en.wikipedia.org/wiki/User_Datagram_Protocol https://en.wikipedia.org/wiki/User_Datagram_Protocol [3] https://tools.ietf.org/html/rfc768 https://tools.ietf.org/html/rfc768 [4] https://en.wikipedia.org/wiki/Transmission_Control_Protocol https://en.wikipedia.org/wiki/Transmission_Control_Protocol [5] https://tools.ietf.org/html/rfc675 https://tools.ietf.org/html/rfc675 [6] https://tools.ietf.org/html/rfc793 https://tools.ietf.org/html/rfc793
