Packet Level TCP Performance of NAT44, NAT64 and IPv6 Using Iperf in the Context of IPv6 Migration

Current allocation rates suggest IPv4 exhaustion by approximately 2011. Hence, this paper will lead the way for the acceptance of Internet Protocol version 6 (IPv6) migration in the Philippines using a similar Network Address Translation (NAT) that there is an apparent means to be taken into consideration and NAT IPv6 to IPv4 (NAT64) can be a good choice for computer networks like the Philippines which is behind NAT44. This paper is a continuation of the previous paper to be published wherein it focused on the packet level UDP performance of NAT44, NAT64 and IPv6 while this paper is focused on the packet level TCP performance of NAT44, NAT64 and IPv6 using iperf. Therefore this paper concluded based on the packet level TCP results wherein overall performance revealed that IPv6 network and NAT64 network offered better performance against the NAT44 network in almost all of instances on the iperf generic TCP mode test. For time transfer, IPv6 had 26% less and NAT64 had 27% less where both executed the transfer in a lesser time compared to NAT44 networks having 45% which is longer than the results of the aforementioned networks. In the bandwidth utilization, it is presented that IPv6 network had 50% and NAT64 network had 33% offered better bandwidth utilization as compared to NAT44 network having 15%. IPv6 network had 43% which showed faster transfer rate along with NAT64 network which had 41% compared to the NAT44 network with only 15% transfer.
