Re: MPLS and Carrier Ethernet, Oh My!

*nods* for PtP, I agree. As a buyer (and a seller) waves, waves, waves. As a seller, it's less stuff for me to manage. 
As a buyer, I don't have to trust you on oversubscribing a wave because you can't. You can oversubscribe the hell out 
of an Ethernet circuit, though. 


Waves are much harder in a PtMP environment, especially with cross connect costs.

These days, it's a LOT easier to get dedicated ethernet wave service between A and Z than it used to be. The pseudowire 
options were developed to fill that gap that customers wanted. 


Still certainly use cases for it, but generally the dedicated waves are much easier to get and probably cheaper. The 
providers would certainly prefer NOT to sell you that service either in most cases, because they don't want the 
overhead of running their parts either, and would like to see it die on the vine.

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.
