When datagrams containing TCP data arrive at a machine, they are given to the TCP entity, which reconstructs the original byte streams.

The IP layer gives no guarantee that datagrams will be delivered properly, so it is up to TCP to time out and（）them as need be. Datagmms do arrive may well do so in the wrong order, it is also up to TCP to（）them into messages in the proper sequence.
