Re: PPP over Ethernet?

  • From: Alan Hannan

   PPP/Ethernet protocol work is proceeding in some standards group
   or another; sorry I cannot name which, I can't seem to find any
   drafts in ietf world (http://www.ietf.org/html.charters/pppext-charter.html)

   Most of the general gist of PPP / Ethernet is to provide a 
   cogent method of aggregating ethernet devices over DSL.

   For example, you may want to have a DSL router that gateways a
   common LAN to a DSL line.

   This DSL line goes into an L2 cloud; ie atm.

   This atm cloud has routers which aggregate DSL subscribers.

   So, you end up w/ something like this:

   (------------ip-------------------)
   (-------------ppp-----------------)
   many users <--dsl--><--atm-->router

   This allows you a unicast pipe between one ethernet mac-address
   and a management point on the router, like a PVC or subinterface.

   This is deemed useful for ADSL customer aggregation over many
   heterogeneous environments, ie, bridged ethernet, etc.

   Among other vendors, Redback Networks is doing some keen work in
   this ara.
