Internet Protocol Suite
TCP/IP is a protocols family (Internet Protocol Suite)
widely used for the dates change
on the internet (and also intranet); this includes the known TCP protocols (4th level)
and IP (3rd level) that are the represent as well as the first to be ideates, and another
(UDP, ICMP, ARP, RARP, etc.).
These protocols occupy the 3 and 4 levels of the OSI model, so basically occupy by the transport, more or less reliable, of the Applications generates dates.
In the next page we will speak about the protocol:
- ARP : already mentioned, permeates the conversion of an IP address with a MAC address corespondent.
- IP : is a protocol of 3rd level and the base of all the Network; is indispensable for the correct forward of the packets, through the recipient IP address.
- ICMP : stays at the 3rd level, but is above IP; makes the useful functions for the forward and for the diagnostic (see ping).
- TCP : is a transport protocol very reliable (and also complex).
- UDP : is another protocol transport, but less reliable of the TCP; has the advantage to have an easy implementation and generally gives good performances.
