Explanation

This layer of the DoD Model is also sometimes called Transport in some books but the proper name is Host-to-Host as per the RFC document. The host-to-host layer provides for reliable end-to-end communications, ensures the data's error- free delivery, handles the data's packet sequencing, and maintains the data's integrity. It is comparable to the transport layer of the OSI model.
