有什么软件可以监视LAN？有什么软件可以监控LAN内各台电脑网络带宽使用情况？
现有几台电脑通过router上网，需要监控各台电脑使用总带宽的情况。
如：总带宽150K，可以看到电脑甲用了15K，电脑乙用了13K......

请说明软件的名称，哪里可以下载。
（最好是免费的，或者可以找到注册码的）

谢谢[CitiNomad (9-9 17:43, Long long ago)] [ 传统版 | sForum ][登录后回复]1楼

You can only get a reliable trace if you are the router!If not, any trace is just an estimate. If you are sharing the same LAN as the other machines only, most packet dumping software will do it fine (provided you are on shared media with the other machines, otherwise, your router will not allow you to see traffic by other machines.)[Flying (9-9 18:47, Long long ago)] [ 传统版 | sForum ][登录后回复]2楼

一点都不象Nomad.哪里的游牧民族这么斤斤计较？:P
平均计算费用就罢了。

只是研究研究网络罢了[CitiNomad (9-9 20:01, Long long ago)] [ 传统版 | sForum ][登录后回复]4楼

No such thing if you access from your hostand the network is well-designed network with security consideration, where if you are not priviledged, you are not able to see any other's traffic.

If you have the access to the distribution/core switch/router, you can use port mirror to "copy" the data to another port where you can have software/hardware network analyzer to calculate the thing.

If you have access, you also can use IP accounting to calculate the average bandwidth utilization in a certain period of time. [香陵居士 (9-9 23:35, Long long ago)] [ 传统版 | sForum ][登录后回复]6楼

(引用 Flying:Pls lah... don't think so chim 1st...A lot of real-life cases are simpler than your situations.)Hoho. It IS real lifeTry to dig out some other's traffic from NUS network? Can you make it?
(It's true in some cases, like some switches in some area are physically not well-protected, you can easily get access and do a port mirror and run away before get caught. :) But in most case I don't think you can.)[香陵居士 (9-10 12:14, Long long ago)] [ 传统版 | sForum ][登录后回复]8楼
