Ethernet over ADSL: Difference between revisions
(IPv4 pool conservation) |

*Features - want per MAC address accounting, uptime graphs, sophisticated firewalling? These could be offerable as a managed service and can be kept up to date.
*Reliability - by making CPE simpler, crashes could be less likely. The ISP manages their datacentre equipment and can restart it as needed without visiting any customers. The ISP might ask the CPE to reflash eeprom remotely if this needed as well. Also possibly good for subscribers connecting ethernet kiosks or ledboards back to their hq.
*IPv4 conservation - the virtual routers can collaborate on address space so that addresses are issued as needed from a single pool or allocated statically as agreed between ISP and customer. Want to borrow a few hundred public IPv4 addresses but only for a day or so? The ISP can even update DNS as IPv4 addresses are allocated, by looking for the device MAC address from stateless IPv6 addresses in the DNS.
*Multicast - easy to support without a featureless router in the way
*Support - the user need not log in to their CPE so the ISP helpdesk can disregard talking a user through troubleshooting it.
