TCP/IP 송수신에서의 Zero-copy 매커니즘 개선 연구

&nbsp;&nbsp;The advancement of the computer and data communication lead to the LAN and network with a wider area network to be developed and it finally reached to the Internet. From the reciprocal connection by this Internet network researchs about the efficiency improvement of the whole system is accomplished with the method which reduces delays in message transmission. From here, we will do a comparative study between the user data program protocol (UDP) and the zero copy which does not use the buffer cache to fine out the valid method to improve the efficiency.<BR>&nbsp;&nbsp;In this thesis, I will change the message copy from execution process of the buffer cache of the TCP/IP on Unix OS with process on Linux OS. The object of conversion is to show you that the zero copy which doesn&quot;t use the buffer cache from transfer control class improves the communication efficiency.
