Toward Resource-Efficient and High-Performance Program Deployment in Programmable Networks

Programmable switches allow administrators to customize packet processing behaviors in data plane programs. However, existing solutions for program deployment fail to achieve resource efficiency and high packet processing performance. In this paper, we propose, a system that provides resource-efficient and high-performance deployment for data plane programs. For resource efficiency, merges input data plane programs by reducing program redundancy. Then it abstracts the substrate network into an one big switch (OBS), and deploys the merged program on the OBS while minimizing resource usage. For high performance, searches for the performance-optimal mapping between the OBS and the substrate network with respect to network-wide constraints. It also maintains program logic among different switches via inter-device packet scheduling. We have implemented on a Barefoot Tofino switch. The evaluation indicates that achieves resource-efficient and high-performance deployment for real data plane programs.
