A short-term solution for the depletion of Internet Protocol (IP) addresses and scaling problems in network routing is the reuse of IP address by placing Network Address Translators (NAT) at the borders of stub domains. In this article, we propose an implementation of NAT using Programming ProtocolIndependent Packet Processors (P4) language, taking advantage of its features such as target-agnostic dataplane programmability. Through the MACSAD framework, we generate a software switch that achieves high performance with the support of different hardware (H/W) and Software (S/W) platforms. The main contributions of this paper relate to the performance evaluation results of the NAT implementation using P4 language with MACSAD compiler.
