Domain-Specific Programming Router Model

Router architecture continues to innovate, performance continues to upgrade and functionality continues to expand, but it still can't support operators to customize network services. On the other hand, the performance and functions of "white box" switches such as Server-Switch based on software defined architecture are better to meet the service requirements of operators. Using DSA (Domain Specific Architecture) as reference, the self-developed programmable switching chip is used as the core of router data plane for innovation. A new programmable data processing unit (dpDPU) based on Reconfigurable Match Tables (RMT) pipeline is designed and implemented to optimize protocol processing and break through heterogeneous accelerated programmable data forwarding plane, software/hardware cooperative protocol control plane, and advanced programming method based on domain language. DPRouter has the advantages of simple structure implementation, high performance switching chip, data processor domain language programming, software defined control and so on. It can simplify the development of network services by operators and lay the foundation for the integration of traditional router and switch devices.
