IntroductionProblem and Literature Survey :

In the today's networking world, the number of network configurations and layouts are unlimited. Yet, understanding the monitoring principles and concepts provides the user with the ability to find a solution that can ensure traffic visibility in virtually any situation.

Naturally, the network visibility is not the final purpose. Rather, it's a base required for the correct usage of network monitoring and analysis software.

As a technical student, it’s our duty to view the trends of the current technologies and try to work with it. So when the idea of final project had come to my mind , I tried to correlate my project with needs of our system.

Existing system

In the existing driver, one buffer is used to achieve the data transmission .

since four transmit registers are there in the controller, we are exploiting all the four registers in the developing the device driver.

Proposed systemThe rtl8139 has got a set of configuration

registers. using this configuration registers,we can configure device.

Since this controller has got four transmit register and one reception register,all the four transmit registers are to be used.

So the transmission becomes faster in the source machine.
