The author discusses their efforts to reduce packet loss in DPDK, which they describe as a persistent issue despite the abundance of related articles. They share their experiences and insights gained during the optimization process, which included increasing ring buffer sizes, optimizing thread tasks, and managing mbuf (memory buffer) releases. The author emphasizes the importance of understanding the underlying causes of packet loss and the role of hardware in the process. They also mention the challenges they faced on the ARM platform and the importance of optimizing for specific hardware architectures. The post concludes with a reflection on the importance of persistence and determination in optimizing complex systems. The text is written in a conversational style and includes code snippets and diagrams to illustrate key concepts. The author's goal is to provide insights and solutions for developers facing similar challenges in their own projects.本文是一篇博客文章，介绍了作者在 x86 和 ARM 平台上优化 DPDK（数据平面开发工具包）性能的经验。作者讨论了他们为减少 DPDK 中的数据包丢失所做的努力，尽管相关文章很多，但他们将其描述为一个持续存在的问题。他们分享了在优化过程中获得的经验和见解，包括增加环形缓冲区大小、优化线程任务和管理 mbuf（内存缓冲区）发布。作者强调了了解数据包丢失的根本原因以及硬件在此过程中的作用的重要性。他们还提到了他们在 ARM 平台上面临的挑战以及针对特定硬件架构进行优化的重要性。本文最后反思了持久性和决心在优化复杂系统中的重要性。文本以对话风格编写，包括代码片段和图表以说明关键概念。作者的目标是为开发人员在自己的项目中面临类似挑战提供见解和解决方案。 | |

It provides fast path processing for UDP, TCP, and ICMP, as well as support for various protocols and tunneling methods. The architecture includes an OFP library, user application code, Linux host system, and network interfaces. The OFP system consists of a main thread, dispatcher, and OFP multicore system view. Main features include fast path protocols processing, IPv4 and IPv6 forwarding and routing, and integration with the Linux slow path IP stack. OFP contains a command line interface for configuration and debugging, and offers optimized zero-copy APIs for single thread run-to-completion environments. Limitations include functional but not performance-optimized TCP implementation. For further reading, check out the project documentation on GitHub.OpenFastPath （OFP） 项目是适用于 IPv4 和 IPv6 的开源加速路由和转发解决方案，专为在数据中心环境中使用而设计。它为 UDP、TCP 和 ICMP 提供快速路径处理，并支持各种协议和隧道方法。该架构包括 OFP 库、用户应用程序代码、Linux 主机系统和网络接口。OFP 系统由主线程、分派器和 OFP 多核系统视图组成。主要功能包括快速路径协议处理、IPv4 和 IPv6 转发和路由，以及与 Linux 慢速路径 IP 堆栈的集成。OFP 包含用于配置和调试的命令行界面，并为单线程运行到完成环境提供优化的零拷贝 API。限制包括功能上未优化性能的 TCP 实现。如需进一步阅读，请查看 GitHub 上的项目文档。 | |
