NetLatency 介绍
NetLatency 是个微秒级别的网络延迟检测工具。
需要在配置文件中简单描述需要测试的网络连接：
[s1] SRC_HOST = sample1.com DST_HOST = sample2.com DST_HOST_INTERNAL = sample2.internal.com [s2] SRC_HOST = sample1.com DST_HOST = sample3.com DST_HOST_INTERNAL = sample3.internal.com
运行后可以输出下面的结果：
| source | target | Ethernet | IP | Latency (micro-second) | |-------------+-------------+----------+-------------+------------------------| | sample1.com | sample2.com | en1 | 192.168.0.2 | 23 | | sample1.com | sample3.com | en6 | 192.168.0.3 | 27 |
