Abstract
Programmable network data planes have extended the capabilities of packet processing in network devices by allowing custom processing pipelines and agnostic packet processing. While a variety of applications can be implemented on current programmable data planes, there are significant constraints due to hardware limitations. One way to meet these constraints is by optimizing data plane programs. Program optimization can be achieved by specializing code that leverages architectural specificity or by compilation passes. In the case of programmable data planes, to respond to the varying requirements of a large set of applications, data plane programs can target different architectures. This leads to difficulties when developers want to reuse the code. One solution to that is to use compiler optimization techniques. We propose performing data plane program specialization to reduce the generated program size. To this end, we propose to specialize in programs written in P4, a Domain Specific Language (DSL) designed for specifying network data planes. The proposed method takes advantage of key aspects of the P4 language to perform a symbolic analysis on a P4 program and then partially evaluate the program to specialize it. The approach we propose is independent of the target architecture. We evaluate the specialization technique by implementing a packet deparser on an FPGA. The results demonstrate that program specialization can reduce the resource usage by a factor of 2 for various packet deparsers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
