This paper is mainly a summary of the detailed solution of tcp/ip protocol after reading.

Summary: the encapsulation formats of Ethernet and ieee802.2/802.3, as well as point-to-point encapsulation formats (slip and ppp) are compared. Since slip and ppp are often used on vulgar links, both provide a way to compress public fields that do not change often, which improves interaction performance

Most implementations provide a loopback interface, generally 127.0.0.1. It can also be given to any IP address owned by the host through ip packets. When the loopback data returns to the upper protocol stack, it has gone through the complete processing of the transport layer and the IP layer.

3 describes an important feature of many links, mtu, and a related concept is path mtu

One of the reasons for 4tcp/ip 's success is that it can run on almost any data link technology.
