Re: Mobile edge?
Actually operators all over the world are implementing IP RAN (end-to-end IP) solutions aiming exactly on the possibility to fast deploy new services and share the unused capacity with other networks. A new IP/MPLS RAN can be used to transport 2G, 3G and 4G/LTE traffic and also carry the packets from UBB and other FTTx access services, all simultaneously. An IP/MPLS network can have many of its functions virtualized and centralized based on the SDN and NFV principles, so we're likey to see a good part of the mobile edge and RAN running on virtual servers in the near future, I mean 3 to 5 years ahead.

Re: Mobile edge?
Virtualization of the mobile base station has already been identified as an early use case for NFV – specifically by members of the carrier community. In all fairness, the NFV work, here, is just an extension of the cloud/centralized RAN (C-RAN) research project initiated by the China Mobile Research Institute. This initiative serves to reduce the general underutilization of RAN that must be architected for peak hours with capacity that cannot be shared.


As you mention, there are baseband processing functions that may not be efficiently realized in software. Remember, however, that in many cases, NFV is finally forcing the issue of control and media plane separation. In this instance, there could be a base band unit (BBU) resource pool serving virtualized eNodeB's, Home eNodeB's, Femto and Pico cells. Obviously, there's work to do, here, in terms of northbound interfaces to the virtualization orchestrator, etc...

Re: Mobile edge?
Agree. I think putting a dollar estimate on the NFV market would be pretty tricky because not all network functions are going to get virtualized at the same time.

Please Show Us the Data!!
I second Carol. It would be wonderful to have a simple, self-explanatory chart documenting the main areas included in the estimate -- servers, software, etc. and some explanation of any special concerns with coming up with the answer.

Re: Mobile edge?
All elements of the telecom network including wireline, wireless, and cable are POTENTIALLY in scope.  I do not include enterprise (business) networks as party of this NFV analysis.

Re: Mobile edge?
So Lee, what do you include in the NFV market? As you say above, it's not all that well defined and could include almost any part of the network.

Re: Mobile edge?
Cloud RAN is an interesting area for NFV.  I think operators will experiement with moving some of the RAN intelligence into the cloud, but the RAN itself is likely to remain specialized integrated hardware.

Mobile edge?
So how much of the mobile edge of the network can actually be virtualized, given the custom chips and other non-standard elements there?
