</div>With DHCP for subscriber management, there are two typical<br>
options:<br>
<br>
1. Run DHCP as a local service on the BRAS.<br>
<br>
2. Run DHCP Relay from the BRAS toward a DHCP server<br>
located somewhere in your core network.<br>
<br>
Unless you're providing walled-garden services (like VoIP,<br>
IPTv, VoD, e.t.c.), MPLS is not necessary for subscriber<br>
management.<br>

</div>If by "per service" you mean per customer, then the quickest<br>
win will be to break each customer down to a VLAN, and offer<br>
IP services to them on individual VLAN's at the nearest IP<br>
router sitting on the back of the trunk to the site.<br>
<br>
If you can afford 30x routers, one for each site, your life<br>
will be simple. If you can't, you can deploy a handful of<br>
routers as far as your budget permits, and aggregate the<br>
sites across those routers accordingly.<br>
<br>
All that said, you'd still do well to look at features on<br>
the WiMAX network that can help control broadcasts and<br>
broadcast storms, as well as implementing storm control<br>
where possible.<br>
