Transport Layer
In Transport layer either in TCP header or UDP header in checksum field we calculate checksum for Pseudo header of IP + header of TCP/UDP + data of TCP/UDP. Transport layer should fill checksum field in header before the Segment pass to Network layer. Here my doubt is how TL knows the IP header which is going to create in next step NL ?

Consider a network having a host P connected to another host Q via two routers Rl and R2. P is connected to R1 through a link that can support a maximum frame length of 1024 bytes including header of size 12 bytes. R1 is connected to R2 through a ... number of bytes that are sent from host P to Q (including all the headers). https://gateoverflow.in/?qa=blob&qa_blobid=626145120644117638
