请问ifconfig中的carrier是啥意思?代表什么呢?这个值很高是不是不正常啊?
来源: 互联网 发布时间:2017-05-22
本文导语: 最近在改网络驱动,改完之后发现ifconfig查看网卡统计信息中的carrier值随着数据量走一直在增加,我记得以前的值一直是0,但是却查不到是啥意思?而且感觉改完之后的网络驱动,网络不是很好。。。 请问各位大牛...

请问各位大牛们,这个是啥意思啊?如果不为0是什么导致的呢?求指点啊!!!!!

TX carriers
The number received packets that experienced loss of carriers.

The carrier is a wave that is used for modulation of signal. The modulated signal consists pure sine wave "carrier" signal which is modified to convey information. Modulation is the conversion of a digital signal represented by binary binary into an analog signal something like a sine wave. A pure carrier sine wave, unchanging in frequency and voltage, provides no flow of information at all. There are 3 basic types of modulation: frequency, amplitude, and phase.

看了些网上的文章,没找到什么明确的结论,大致如下:
这个carrier就是CSMA的C,也就是载波。它的值很高表示出错很多,导致网络性能下降。通常是物理层的错误造成的,比如电缆问题、强电干扰、等等。但看你的情况又不太像...

这个值应该是越低越好

网络驱动能ping通局域网么?看下中断是否都能收到,有没有丢包。
