Análise de escalabilidade e desempenho de aplicações de rede em DPDK

Abstract

Communication networks play a fundamental role in our society, supporting a wide range of services and applications. However, as these networks grow in complexity and service demands evolve, there is a need to make them more flexible and adaptable. Network programmability, driven by technologies like P4, eBPF, and DPDK, offers the ability to customize network behavior, allowing real-time innovations and optimizations. P4 allows programming the network forwarding layer, while eBPF extends programmability to the kernel of the operating system, and DPDK accelerates I/O operations for high performance. Network programmability is essential for several reasons, including the dynamism of applications, the need for scalability and efficiency, the importance of security and monitoring, the adoption of new technologies, and the customization of services. The ability to program the network according to specific requirements is a competitive advantage and contributes to smarter and more adaptable network infrastructures. This work focuses on evaluating the scalability and performance of applications developed in P4 when transferred for execution at the user level through DPDK. The goal is to identify incompatibilities and assess the performance of these applications in a data plane programmability environment in DPDK. This information can serve as a guide for future implementations and contribute to the advancement of network programmability technologies. Keywords: DPDK, network programmability, P4.
