Abstract
In this paper we evaluate the UDP performance of IPv6 in a peer-to-peer Gigabit Ethernet network using the latest four different MS Windows and Linux-based client and server operating systems (OS). The throughput and end-to-end delays are measured empirically to determine which OSs provide the best bandwidth performance over IPv6 networks. The impact of packet length on system performance is also reported. Results show that for IPv6 Linux network using Ubuntu 10.04 performs significantly better than Windows 7.
