Abstract

Programmable networks, driven by SDN and P4, offer flexibility but lack solid standards and methodologies. The absence of standardized interfaces and tests in SDN, along with low-level programming in P4, leads to challenges such as code conflicts, vulnerabilities, and low reusability. To address these limitations, ProgNet leverages GNU Radio’s modularity to organize SDN and P4 networks more intuitively. By adopting a top-down approach, it aligns software development with network objectives, preventing performance issues. A case study demonstrates component reuse and optimization of latency and throughput, validating the feasibility of modularity and standardized interfaces.

Keywords: Programmable networks, SDN, P4, ProgNet, modularity, GNU Radio, component reuse
