I have a linux box configured as linux bridging and running
ntop. I have this box positioned between a WAN router and a
LAN switch, like follows:
SW: Ethernet switch
FR: Frame relay router
Link1: 64 kbps
Link2: 512 kbps
* There are ten 64kbps links connected to FR2, due to its
My doubt is regarding the "Peak" data available in the
Network load page. Im considering all traffic
I got a peak value of 264 kbps from an address (pc) that is
behind of Link 1 (64kbps).
The explanation about the peak values, at the end of the
page, is that this value is obtained each ten seconds.
I cant realize how is possible this 264 kbps peak value,
considering the physical limitation of link1. As Im
looking for the all traffic (send+receive) and considering
the link1 as full-duplex and synchronous, I understand that
is possible, when the pc is sending and receiving (same
time) bursts, to see values near from 128 kbps, but not
1. Is my understanding of this ntop value (throughput peak)
2. Has someone experimented something like that ?
In advance, thank you!
