SLA for ISP

Hello all,

We are offering a wireless broadband service. We have a residential offer at different speeds (128,256,512,1024). All users are using the same dhcp server to get an IP and we have different ip addresses pools (we cannot use static IP assignements through DHCP). We also have a bandwidth manager to limit the traffic based on IP addresses range. Actually, we have all that users in the same “pipe” sharing a certain bandwidth. It’s working fine but the problem is that during peak hours, all users have the same level, for example a user at 128 and a user at 512 will get individually a maximum of 40 Kbps.

We are looking for a way where we’ll be able to separate the pipes, meaning we’ll have one pipe for all our clients at 128 Kbps, one pipe for all Clients at 256 Kbps, etc…. and so during peak hours, users at 128 will have 30, users at 256 will have 70, etc…. The values used are just for examples.

Thanks for any advise you can provide me.

Regards

I did something like this before in a wireless ISP

I used a freebsd machine with dummynet, i had 2 different variants - day & night .. businesses got more bandwidth during the day, residential got more at night.. simple, what hardware are you using to manage your bandwidth?

We are using Allot Netenforcer.

We actually have different pipes by IP addresses and day and night rule, but we need a "deeper" bandwidth control.

We'll take a look at the different articles posted here and let you know.

thanks

We have found a solution based on vlan control, we are in the process to test it in the next couple of days
