RE: [squid-users] Delay pools explained ??

Would I then be correct in assuming that class 1 is more for
when one wants to apply separate limits to separate machines,
for instance if you have a parent cache and you would like to
specify how much bandwidth each child gets based on the link speed
it has to parent i.e. I have 5 children with line speed 64, 128, 196
256 etc I would use a 5 class one pools?

Is there a limit on the amount of pools one can create, and I suppose
the more pools you have the bigger the overhead (mostly memory)?

Thanks for all the help so far, I now have a working setup with delay
pools.

Regards
Rabie

If you have more than one class B networks where the last 16 bits may
overlap significantly then you should create multiple class 3 pools. If
the same last 16 bits are very unlikely to be used concurrently in more
than one network then you may get by with only one pool.

For the multiple 24bit networks it is up to you if you create multiple
class 2 pools or one large class 3 pool.

Creating multiple pools is needed if you want to apply different
settings to different networks.

class 2 uses the last 8 bits of the client IP address as "user
identity".

class 3 uses the last 16 bits of the client IP address as "user
identity".

And in addition to the aggregate and per user limits class 3 pools also
have network pool limits which works like the aggregate pool limits but
apply to the 24 bit networks. A class 3 pool has 256 networks of 256
client IP addresses, based on the last 16 bits of the client IP address.
