The P4 language is a language suitable for the description of packet processing inside a network device. The typical P4 device consists of three main building blocks: Parser, Match+Action Tables and Deparser. The deparsing is the most challenging block because the main task of this block is to assemble the output packet based on changes in Match+Action Tables. This operation can be quite complicated in the case of high-speed networks. In this work, we present the scalable architecture (in term of the throughput) of a deparsing circuit which is suitable for implementation in FPGAs.
