Re: MPLS and Carrier Ethernet, Oh My!

They’re out there.  I’ve helped stand up carriers recently that sell them and have also bought such service from other 
carriers.  At least for 100G.

I haven’t seen 400G Ethernet point to point services but also have not been asked to engineer to sell them either so I 
suspect that demand is either soft or the majority that want 400G point to point today are as Aaron says electing to 
serve that need via alternate solutions .

Since 2023, we’ve (GVTC) been migrating our CBH MTSO handoffs and partner ENNI’s from 1g/10g to 100g.  …moving off 
older ME3600’s, ASR9k’s and ACX5048’s, to newer MX series (204,304,240,480,960)

A few years back, every Tom, Dick, and Harry was touting MPLS or Carrier Ethernet NNIs with 10G ports everywhere. They 
still are. However, I rarely have seen that graduate to 100G ports and I don't think I've seen anyone talk about 400G 
ports.

Is the hardware not there, or is it more a case of the technology hasn't been deployed widely, so it'll only be seen at 
a limited number of locations? I'm assuming it's more of the latter as the bigger hardware I've been looking at touts 
those features and port sizes, but maybe there's some other unadvertised limitation.
