Evaluation of IPv6 with IPSec in IEEE 802.11n Wireless LAN using Fedora 15 Operating System

IPSec (IP Security) is a robust technique for securing communications over the Internet. Due to security algorithms used, transferring data using IPSec is known to be significantly slow. In this paper using a test bed environment for a site to site IPSec, we present new results on performance of IPSec for both IPv4 and IPv6 using Fedora 15 operating system and wireless network. Compared to open system, enabling IPSec results in approximately 50% and 40% less throughput for IPv4 and IPv6 networks respectively
