各位大虾们：

    下面是我在一台视频服务器上通过.tcpdum.p抓包得到的一些信息--- 印刷

其中有大量的如.红色字体的记录，同时我们也发现手机用户做点播视频.的同时也经常出现点播不了或者经常缓冲的情况。虚拟主机

这种问题我还是第一次见到哦（呵呵，其实.我刚出来工作久，只有几个月而已），百思不得甚解，百.度、GG都找遍了也找不到答案。.

我想问一下这里的大虾们，这一般是由于什么原因引起的？或者我还应该再做什么其他的测试获取.信息供大家参考.？健康

先就此谢过啦。。

烧钱的公司，视频有前途呀
你的tcpdump上看到的应该是ip的数据不完成，应该是网络的原因，具体要使用tcpdump -vv进行抓取查看的

这个是通过 tcpdump -v 抓来的，大家可以看出什么来吗？？
