Performance Comparison of IPv6 in 802.11ac WLAN in Windows and Linux Environment

In this paper, the performance of IEEE 802.11ac wireless LAN is analysed and compared for two operating systems, Windows, and Linux Ubuntu. Parameters measured are throughput, latency, and CPU utilization for TCP, UDP, IPv4, and IPv6. For both wireless 802.11ac network implementations studied, client-server and peer-to-peer, our results shows that the throughput for both Windows and Ubuntu is much higher in IPv4 than IPv6. IPv6 also has higher RTT and higher CPU utilization than IPv4. TCP has lower bandwidth than UDP, and Windows had lower throughput than Linux. The highest throughout achieved in systems considered is for client server with IPv4 and UDP at throughput of 757Mbps for Windows and 798Mbps for Ubuntu. For channel size of 80MHz we could not reach theoretical limit of 1.3Gbps for wireless LAN 802.11ac.
