Abstract
:
For convenience of network programming, in the
early 1990s, a new set of network programming interface
using under WINDOWS was established by some
companies united by Microsoft. It is known as Windows
Socket Norm. It isn't a kind of network protocol, but an
open network programming interface support multiple
protocols under WINDOWS. The main purpose of the thesis
is to introduce how to use Winsock2 program on network
adapter under the protocol of TCP/IP. This is for the
purpose of measure the network discharge. At the
beginning of the thesis, we introduce all important
protocols of TCP/IP, like IP, TCP, and UDP. We introduce IP
header, TCP header and UDP header for the most
important because we need acquire the information of
source address, destination address, and protocol type
from the IP header.
In the following section, we give the concept of Socket.
Sockets actually provide a communication port to allow all
the computers that have Socket port to communicate with
each other. In the thesis, we talk on the process of the
