# 基金会来信

欢迎阅读 FreeBSD 期刊 2018 年秋季网络专刊。我们的第一篇网络文章由 Jonathan Looney 撰写，涵盖了我一直非常感兴趣的测试主题。软件测试已经很难，测试网络代码——实际上就是测试分布式系统——难度更大。Netflix 在其缓存服务器中使用 FreeBSD，他们对在 FreeBSD TCP 栈中所做变更的性能和正确性都很关注，因此良好的测试系统的严谨性对他们和整个 FreeBSD 来说都非常受欢迎。

Ayaka Koshibe 贡献了一篇关于软件定义网络（SDN）和 Mininet 的文章，Mininet 是知名的 SDN 协议模拟器。过去几年她一直在会议上展示围绕这个主题的工作，我很高兴我们说服她为期刊撰写一篇关于这个主题的文章。

第三篇文章《FreeBSD 中的网络互联》由本主编亲笔撰写，所以我在这里就不剧透了。

为了完善这个专题，我们还有一篇 Matt Macy 撰写的文章，讲述如何在现代服务器硬件上扩展 FreeBSD 的性能。虽然 FreeBSD 部署在多种类型的硬件和环境中，但在配备多 CPU 核心和大容量内存的高端服务器上，其性能仍是 FreeBSD 整体成功的关键。

请查看我们所有的专栏，特别是新的读者来信专栏，Michael Lucas 以委婉而诙谐的笔触回答你的来信。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://freebsd-journal-cn.bsdcn.org/20180910-wang-luo/foundation-letter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
