Hello,
We are a small isp using cisco router for internetworking and
now want to switch to linux. We know it works fine as a router
and an access router, but wonder if it can use "fair queue" similar
to that of cisco. Now we use custom queue in our cisco router, so that
if only one of our leased line customer is active, she can use the whole,
say 256K, bandwidth of our link to Internet. If two customers are active, they can
share the 256K bandwidth. However, if all customers are active, each of them will
at least has, say 64K bandwidth. Please let me know if linux is capable to do that ?

Thanks and Regards
Wong

Wong,
I do think you can do fair queue type of functions with Linux.
These type of functions are handled at the O/S level. So unless
some builds support in the Linux kernel it will not be possible.
This is done at the IOS (Cisco's operating system) level in a
cisco router.

Linux routing appicalition do support BGP and OSPF; therefore
you can get similar results in non-access routing configurations.
So, I guess it depends if you and your customers are using these
routing protocols.
