Since IPv6 was born in 1995, IPv6 has never been a major issue until the IPv4 was exhausted in 2011. Now the internet protocol is migrating from IPv4 to IPv6. The issues about IPv6 transmision performance are great concerned by many people during this migration period. In this study, we evaluate the performance of IPv4 and IPv6 through file transfer. The evaluation includes two testing scenario: BPEL file transfer testing scenario and FTP testing scenario. Besides file transfer, we also analyze the performance differences of IPv4 and IPv6 through RTT and hop count. We use “ping” and “tracert”as the tools to evaluate IPv6 transmision performance in terns of RTT and hop count. In FTP testing scenario, we send various sizes of files like 1MB, 5MB, 10MB, 50MB and 100 MB to FTP remote server. The evaluation shows that IPv6 can provide better performance than IPv4. In BPEL file transfer testing scenario, we use OpenESB as the testing platform. OpenESB is an open source project, which provides programming interface containing BPEL engine. Since the FTPBC module in OpenESB does not support IPv6, we develop IPv6 version FTPBC module and contribute this module to the open source project. Based on our IPv6 version FTPBC module, we perform the similar file transfer test scenario. The evaluation also shows that IPv6 can provide better performance than IPv4. Both evaluation results all indicate that IPv6 is better than IPv4 in terms of performance. It shows that IPv6 is ten percent to forty percent faster than IPv4 both in FTP and BPEL. We also found that IPv6 is faster than IPv4 when it is used to perform file transfer in day time. Our analysis indicates that IPv6 has advantage in fixed packet header while packet header in IPv4 is not fixed. In addition, Routers perform fragmentation in IPv4, whereas in IPv6, routers do not fragment, fragmentation is performed in the host. Therefore, IPv6 has better performance in terms of file transfer. We can expect that IPv6 is going to be accepted by general users, and will replace IPv4 in the near future.
