Introduction:
Most network application can be divided into two programs: client and server with the 
communication link between them as shown:
Clinet Server
Examples are : A web browser communicating with a web server. A FTP client fetching a file form an 
FTP server etc. A client normally communicates with a server at a time. However, a server is likely to 
communicate with multiple client. The client and server communication with in the same Ethernet and 
the communication when LAN connected through WAN is shown below.NPM/U-1/2
As seen in above figure , TCP and IP protocols are normally part of the protocol stack within the 
kernal. In addition to TCP and IP, other protocol like UDP is also used. IP that was in use since early 
1980 is called as IP version 4 (Ipv4). A new version IP version 6 (Ipv6) is being used since mid 1990.
OSI model for the Internet protocol suite: The following figure provides the comparison of OSI 
reference model with that of Internet protocol suite.
The upper three layers of OSI model are combined into a single layer called the application. 
This is the Web Client (Browser), Telnet client, the Web Server, FTP server or whatever application 
we are using. The transport layer that are chosen are TCP and UDP. As shown in the figure, it is 
possible to bypass both TCP and UDP and the application layer may directly use Ipv4 or Ipv6. This is 
called raw socket.
The two program interface the we will be studying are sockets and XTI(X/Open Transport
Interface) . It is intended to study : how to write applications using either Sockets or XTI that use
either TCP or UDP. We need this because, upper three layers handle all the details of the application 
(FTP, Telnet or HTTP etc) and know little about the communication details. Whereas the lower four 
layers know little about the application but handle all communication details: sending data, waiting for 
an acknowledgement sequencing data that arrives out of order , calculating and verifying the 
checksums and so on. Upper three layers are normally provided as part of the operating system kernal.
