What I have in mind is actually to combine line-rate ODUs with a static mapping and pipe the uncommitted capacity to a packet-switch.
Statically commited services will be muxponded in fastpath, hence no jitter and less latency, while the fractionnal ports use the remaining ports, mostly for low-priority IP traffic.
Now I was assuming ODUFlex in CBR mode would allow fractionnal services without packet switching, but mapping an ethernet service to it would require some equivalent glue logic I guess, specifically for this case :
I see what you're getting at. It sounds like you want to light up a 100Gb wave, put some committed "dedicated wavelength" services on it, then take whatever's left and hand it off on 100GbE for best-effort/general Internet traffic. Not a bad idea. I guess the idea would be to dynamically provision a FlexODU or something for the remaining bandwidth and switch the Ethernet traffic onto it encapsulated in GFP-F. I see no reason why this isn't possible, but I know of nothing that would do it. So someone needs to make a box with a couple QSFP+ (breakout capable), a couple SFP+, a QSFP28 UNI for the 40/100GbE with subrate commit, and a QSFP28 NNI to speak OTU4 into the network that supports all that. Let me know if you find it! :) -- Brandon
