The primary duties of the transport layer, Layer 4 of the OSI model, are to transport and regulate the flow of information from the source to the destination, reliably and accurately. End-to-end control and reliability are provided by sliding windows, sequencing numbers, and acknowledgments To understand reliability and flow control, think of someone who studies a foreign language for one year and then they visit the country where that language is used. In conversation, words must be repeated for reliability and to speak slowly so that the meaning of the conversation is not lost, this is flow control.
