Dave, GbE, or more likely 10GbE is needed for its rudimentary transport attributes only, such as framing, timing, etc. It could also be a scaled down, skinny form of SONET where Packet of Sonet (POS) is used.
Note: the article I'm citing here from Arnaud is a year old to the day. Therefore it is not surprising that he didn't use the 10GbE model in his work at the time of the writing, as I have in our fictitious network. Speaking of which, we may as well give our network a name. Any suggestions? How's SIFNet sound? For SI Fictitious Network?
On top of 10GbE the rest of the networking challenge would be handled at the IP layer and above, for the most part.
I just did a scan of the CANet article you provided, and it overflows of GbE, both implicitly and explicitly. Do a search on "Ethernet" in the body of the paper. Here are a couple of examples, below.
"The GITH network would connect directly into the high speed Ethernet
port of the computer or similar device which would then route the traffic
within the house. There would be no need for telephone interface devices
or expensive digital set top boxes to segregate and deliver multiple
services."
"4. The use of a simple low cost framing protocol such as Gigabit Ethernet
to transport the data;"
"A 64 channel metro DWDM fiber ring can provide up to 150 pair wise
connections depending on how many wavelengths can be re-used. Each
one of these channels can support a dedicated Gigabit Ethernet or an
OC-48 connection."
======
I know where your biggest areas of concern would be.
What may seem like a real problem here is NOT the implementation of 10GbE,
per se, rather, how to invoke the broad range of administrative and service
feature capabilities which are now supported by head ends and voice
telephony exchanges. In the IP space these solutions exist in their own
individual spaces. The need here is to have some body orchestrate how
they are to take place over a single network.
Okay, I've gotten us this far by bringing packet-over-10GbE-over-DWDM to the fore. The rest of the network is up to you. Or, those poor souls over in the Internet Engineering Task Force (IETF). -g-
