Towards the scalability comparison of the Jool implementation of the 464XLAT and of the MAP‐T IPv4aaS technologies

Abstract

Summary 464XLAT and MAP‐T are both IPv4‐as‐a‐Service technologies aiming to provide IPv4 service to the customers, while ISPs use only IPv6 in their access and core networks. The ISPs need to consider several different aspects, like scalability, compatibility with the applications, and efficiency of public IPv4 address sharing, when selecting the most appropriate IPv4aaS technology for their specific application scenario. The aim of our current effort is to make an initial step towards the comparison of the scalability of the 464XLAT and of the MAP‐T IPv4aaS technologies. We point out the gap between the most desirable measurement method and the available testing tools. We measure the scale‐up of the performance of the Jool implementation of 464XLAT and MAP‐T as a function of the number of active CPU cores up to 16 cores using an available testing tool called dns64perf++. We fully disclose our detailed measurement setup and our results, as well as the analysis of our results pointing out the bottleneck during the measurements. We also outline the directions of our future research
