随着网络设备和通道吞吐能力的急速发展，网络规模在不断变大的同时网络架构也变得更加复杂。而当下信息社会中的各种生产、经济和文化活动业务都高度依赖于网络，这就要求网络运维工作人员在处理网络故障时，第一时间找出故障原因，及时排除网络故障，7x24小时365天保障网络的稳定运行。说起来轻松，但做起来并非易事。一旦发生网络问题，找到故障位置是首要任务。网络管理员打开Wireshark或者是Tcpdump工具，猜想着可疑的故障原因，开始抓取数据包，一一排查。对于“老司机”来说，或许他拥有足够的经验能够以极高的概率抓住故障点;但对于普通网络管理员来说，大海捞针般的排查着实难以忍受。抓包不是目的，将数据包解析...
With the rapid development of network equipment and the channel capacity, network scale is larger and the network architecture is also becoming more complicated. Right now, the information society in various production business, economic and cultural activities are highly dependent on the network, which requires the network operations staff in dealing with network failure, find out the cause of the problem, the first time in a timely manner to eliminate network fault, 7 x24 hours 365 days to ensure the stable operation of the network. Make it sound so easy, but is not easy to do. In case of network problems, find the fault location is the primary task. The network administrator to open the Wireshark or Tcpdump tool, guess the suspected the cause of the problem, started to grab packets, one by one. For "old driver", maybe he has enough experience to be able to seize the point of failure with extremely high probability; But for ordinary network administrators, the screen like a needle in a haystack is really unbearable. Caught is not the goal, to parse the packet...
