4、杂项测试
1）流媒体信息，情况就是这样了。
2）国内测速，可以看到国内三网速度全部跑满，很赞！
3）国外测速，欧美测试结果看跑的也很不错。
4）磁盘FIO读写，读写速度很猛！！
5、路由测试
电信回程，直连，走cn2 gia线路

移动去程，走移动cmi
6、ping值
数据提供：ping.chinaz.com 这个ping值也能看出线路非常的赞。
7、路由掉包
掉包情况良好，国内国际线路访问都很优秀。结果非晚高峰测试，晚高峰继续补一张图。
8、UNIX Benchmarks
单核得分：1970.6，很强悍啊，单核堪比Intel的双核。
9、最后
1）线路总结，具体线路看第二条的备注
电信：双程cn2 gia
联通：回程cn2 gia ，去程cn2 gia+AS4837
移动：回程cn2，去程cmi
2）关于去程线路的说明
三网 JPN > CHN 方向将主要使用 CTGnet。
去程将视情况优化，CTGnet去程并非最优，丢包率和延迟均不是最优。特别是对于移动用户以及联通用户。
CMI去程将使我们与移动用户直接通过 SHA – TYO 直接连接。
DMIT与10099 通过10G端口连接，拥有更大的出口速率，并且CTGnet 与 4837 互联有限，时常拥堵。
注：
1. CTGnet ~= CN2. 不同的是 CTGnet 有 GT / GIA 和 中国流量百分比。
2. CTGnet 100% GIA 的 Layer 3 几乎完全等于 CN2。DMIT 在日本订购的本产品。
3. CTGnet 使用自己的海底光缆与中国境内CN2 的PoP 连接。CN2的光缆故障很多时候是手动调度，CTGnet 由 CTG 维护，拥有更快的错误响应。
4. CMI SHA-TYO 虽然是Layer 3 直接连接，但是Layer 1 层，CMI使用的 NCP 海底光缆仍然需要经过韩国。
5. CMI 与 10099 仍未开通，由于交付延期过长，DMIT不愿继续负担CTGnet空转导致的浪费，故先将Pro 提供OpenBeta 销售。
6. OpenBeta 期间会有很多调试，无法保障SLA，我们将尽可能降低各类维护的时长，以及避开东亚所有时区的高峰时段。
