How packets are reassembled?

IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size. The fragments are reassembled by the receiving host.

How are TCP packets reassembled?

TCP is a stream protocol. You can assemble the stream to its intended order by following the sequence numbers of both sides. Every TCP Packet goes to the IP level and can be fragmented there. You can assemble each packet by collecting all of the fragments and following the fragment offset from the header.
