可编程数据平面(PDP)一方面支持网络应用的卸载与加速, 给网络应用带来了革命性的发展机遇; 另一方面支持新协议、新服务的快速实现和部署, 促进了网络创新和演进, 是近年来网络领域的研究热点. FPGA因其通用的计算架构、丰富的片内资源和扩展接口提供了多种可编程数据平面的具体实现, 支持更广范围的应用场景. 同时, FPGA还为探索更通用的可编程数据平面抽象提供了可能. 因此, 基于FPGA的可编程数据平面受到了学术界与产业界的广泛关注. 首先分类别阐述基于FPGA的可编程数据平面(F-PDP)抽象. 接着, 介绍基于F-PDP快速构建网络应用的关键技术的研究进展. 之后, 介绍基于F-PDP的新型可编程网络设备. 此外, 从提升网络性能、构建网络测量框架以及部署网络安全应用这3个方面, 详细梳理近年来基于F-PDP的应用研究成果. 最后, 探讨F-PDP未来可能的研究趋势.
The programmable data plane (PDP), allowing offloading and accelerating network applications, creates revolutionary development opportunities for such applications. Also, it promotes the innovation and evolution of the network by supporting the rapid implementation and deployment of new protocols and services. It has thus been a research hotspot in the field of the network in recent years. With its general computing architecture, rich on-chip resources and extended interfaces, field-programmable gate array (FPGA) provides a variety of implementations of PDP for a wider range of application scenarios. It also offers the possibility to explore more general PDP abstraction. Therefore, FPGA-based PDP (F-PDP) has been widely concerned by the academic and industrial communities. In this study, F-PDP abstraction is described by category. Then, the research progress of key technologies for building network applications with F-PDP is outlined, and programmable network devices based on F-PDP are presented. After that, the application research based on F-PDP in recent years is reviewed in detail from three aspects: improving network performance, building a network measurement framework, and deploying network security applications. Finally, the possible future research trends of F-PDP are discussed.
