The 3rd. Place. Neutron 网络的计算资源隔离与通过 TRex 测试网络性能. 对于 OpenStack 原生的 Neutron 网络，往往诟病良多，核心问题就在性能无法满足生产环境的要求。 Neutron 的网络构成非常复杂，以一个典型的 OpenStack 网络节点为例，所使用的核心组件包括但不限于下面的模块/软件. Linux Kernel 协议栈，包括系统软中断到完整的 TCP/IP 协议栈，用以收发报文、路由和策略路由等. Iptables，作为内核模块，与 conntrack 共同完成带状态的 DNAT 与 SNAT，如果有安全策略，例如 FWaaS 或者 LBaaS 的安全组，则也需要 iptables 过滤报文. Tc，用于收发报文的限速，例如浮动 IP 的限速，社区版代码并没有这部分，但如果厂商需要实现浮动 IP 限速，比较常见的方法是在这里做，此外如果有厂商希望提高 1:1 NAT 的性能，也可以通过 tc 实现，但比较少见. 此时如果通过 Open vSwitch 控制带宽，效果会比 tc 好一些，如果使用 Flow director，效果可能会更好。

The 3rd. Place. Pro Git 阅读笔记四 内部原理. 说实话，第四章之后我只比较仔细地看了第五章 分布式Git ，不过里边的内容很多在比如 Got Github 和其他一些小文章 比如关于Gitflow的文章 也看过了，所以第四章到第八章都没怎么留下笔记，至于第九章完全是对Git的实现还是有一点兴趣所以也粗略地看了下，并没有深入的进行实验，毕竟时间还是很紧，有许多事情要做，以后对Git的学习还是留在开发过程中吧，其实用好前三章的第五章介绍的内容对我已经在平时够用了.
