1. someone from my office said me that Squid delay pool will some time loose the bandwidth restriction and will allow the users to use the full bandwidth.
There is a couple of bugs/misfeatures causing this, most notably if you run "squid -k reconfigure".
It should not happen in normal usage however.
2. If I resctict the bandwidth for some, 5 users, to 128Kbps on a 256Kbps link, will all the other users, who are not in the restriction(Delay Pool) list, have the full 256Kbps bandwidth, when those 5 users are not using their 128Kbps bandwidth.
No, Squid does not have any hierarchical delay pools allowing for bandwidth lending.
3. I want to confirm the 1st point, because I have one
requirement in my client place like, they are having a
256Kbps link in which the ISP will give the 64Kbps as
dedicated and the rest 192Kbps will be on the charging
basis. So if my client crosses 64Kbps, they will be
charged on how much Kb they have used. So, Only if
they require 192Kbps, they can switch to the full B/W
I will set the bandwidth restriction to 64Kbps
using Squid Delay Pool, and when required full B/W I
will make the limit to 256Kbps. Will this work
perfectly?
In general yes but it depends a little on how this "dynamic bandwidth charge" works as there will be short bursts of higher traffic while the TCP receive window is filled.
