Performance of NAT64 versus NAT44 in the Context of IPv6 Migration

Tayga -- out-of-kernel stateless NAT64 implementation for Linux that uses the TUNnnel (TUN) driver. を使用して実験NAT64している。

stateless NAT64か。

RTTとCPU utilization,Throughputでを実際のネットワークと、実験ネットワークで比較。NAT64の方が良い結果と言えるほどの差ではないが、NAT44より悪くはなっていない（良い結果をだせてる）。

Measuring IPv4 – IPv6 translation techniques

2012

NAT-PT is a stateless IPv4 to IPv6 translator that maps IPv4 addresses to IPv6 addresses, while NAT64 is a stateful IPv6 to IPv4 translator that maps IPv6 addresses to IPv4 addresses. During the experiment, NAT64 was found to be more efficient than NAT-PT in managing a large amount of session state with many simultaneous connections. The median RTT of NAT-PT was greater than that of NAT64

The very common P2P and VoIP applications were not working at all with NAT64

Performance Evaluation of IPv4/IPv6 Transition Mechanisms

ISATAP, 6to4, and NAT64(TAYGA and Jool)　

今までNAT64ソフトウェアはJoolしか知らなかったが、TAYGAはパフォーマンスに問題があるしメンテされていないようなのでOSSのNAT64はJoolしかないのかな。

Jool is a stateful NAT64 implementation that works in the kernel space, while TAYGA is a stateless NAT64 implementation (used together with iptables to provide stateful NAT64) that works in the user space.

ISATAP stands for Intra-Site Automatic Tunnel Addressing Protocol. It is a mechanism that allows IPv6 packets to be transmitted over an IPv4 network by encapsulating the IPv6 packets within IPv4 packets.

6to4 is a system that allows IPv6 packets to be transmitted over an IPv4 network without configuring explicit tunnels. A 6to4 site can have up to 2^80 IPv6 addresses of the type 2002:<IPv4Address>:/48

RTT計測の結果

Native IPv4 has a better performance than native IPv6 in controlled testbeds. This is due to the length of the IP headers (20 bytes for IPv4, and 40 bytes for IPv6). Also, our experiments showed that generally, ISATAP and 6to4 have similar network performancesNAT64 where one IPv6 and one IPv4 packet serializations are needed.

MAT64に関しては、Jool の方が性能が良く、TAYGAはパフォーマンスに問題がある。

RFC8219: Benchmarking Methodology for IPv6 Transition Technologies

Before a Tester can be used for testing a DUT at rate r queries per second with t seconds timeout, it MUST perform a self-test in order to exclude the possibility that the poor performance of the Tester itself influences the results. To pass the self-test, the Tester SHOULD be able to answer AAAA record queries at rate of 2*(r+delta) within a 0.25*t timeout, where the value of delta is at least 0.1.
