Unless it's specifically configured otherwise, yes.
It's a basic part of the tcp/ip protocol. You might start reading here http://en.wikipedia.org/wiki/Transmission_Control_Protocol,
continuing on to the links at the end of the "Data Transfer"
section.

[mailto:[EMAIL PROTECTED] On Behalf Of
Burton Strauss OK, so what is
surprising about a peak of 6something on a 100 Mbps
link??? Unless the upstream
router is specifically configured to throttle the flow, any flow control to the
2 Mbps CIR is going to happen at the 2 Mbps interface, based on congestion, not
at the upstream router. Even if the upstream router IS configured for flow
control, you need to figure out what the CIR and BIR rates
are. ----- From: [EMAIL PROTECTED]

Matthew Moore Hi, Basically it looks like
this – ------- (100MB)
Upstream Router ---------- (45MB) ----------- Router ------- (2MB) --------
Customer Router The Upstream router is
running Netflow and sending the information to NTOP which is on part of our core
network. Cheers Matt From: [EMAIL PROTECTED]
[mailto:[EMAIL PROTECTED] On Behalf Of
Burton Strauss Well, limits are often
quoted as CIR (Committed Information Rate), but allow bursting to higher
rates. But without understanding the network layout and where the sensors
are, I can't begin to guess. ----- From: [EMAIL PROTECTED]

Matthew Moore Hi, I have installed NTOP 3.1 and I am
using the Netflow Plugin with it. It is collecting data fine but for example a
customer of ours is on a 2MBs fixed speed leased line and the NTOP stats are
saying that the peak data throughput is 6.7MBs. How can this be
possible? Many
thanks Matthew |
