Data plane programming enables the programmability of network devices with domain-specific programming languages, like P4. One commonly used P4-programmable hardware target is the Intel Tofino switching ASIC. The runtime behavior of an implemented P4 program on Tofino can be configured with shell scripts or a Python library from Barefoot provided with the Tofino. Both are limited in their capabilities and usability. This paper introduces the Rust Barefoot Runtime (RBFRT), a Rust-based control plane library. The RBFRT provides a fast and memory-safe interface to configure the Intel Tofino. We showed that the RBFRT achieves a higher insertion rate for MAT entries and has a shorter response time compared to the Python library.
