Because the customers are permanently On-Line du to the VoIP-Telephone, we count with the full number of clients... The distance between the FTTH DSLAM and the customers can be up to 10km. The idea is now, that we do not simply connect the FTTH DSLAM's to the CISCO switches but building a redunant Ethernet Carrier Network. This mean, we can install in each village there own FTTH DSLAM even if there are 2500 hausholds and we install 26 FTTH DSLAM's there. This mean in theorie 250 GBit Customer Downstream, 26 Gbit Upstream but we count with a 10 GE which is maybe used to 30-50%. OK, if we switch to an "Ethernet Carrier Network" I could install one or two PPPoE Servers in each village. But if one goes down, the second has to handel 2500 client connections. Note: This is ONLY the base installation between Kehl, Rheinau, Renchen and Oberkirch (arround 35.000 hausholds) and the whole region has 150.000 hausholds. > Don't understand what you mean round-robin and loadbalancing? > Read below. > FreeBSD has a RADIUS library in base.

It depends on how many customers you have and with an Internet access of 100 Mbit plus services like IPTV and VOD you can fill up a 10 GE pipe. > I *think* having more low fidelity BRASs, will serve your > needs better that a few high fidelity ones.
