" optimized for the massively varied use cases of the next mobile generation, for cloud services, and for virtualization and software-defined networking (SDN)."
Only wireless is different from point of view of TCP/IP stack and protocol compared to the others.
"Cloud Services" = Remotely connected servers, nothing new here.
"Virtualization" is irrelevant.
" software-defined networking (SDN)" isn't really about TCP/IP at all. It's infrastructure management.
Radio unlike cable*, fibre and in house networking suffers from variable packet loss (other fixed cable/optical links have almost none to zero) which can be high. Wireless has unpredictable variable latency and speed too. The other technologies at the link level are pretty much fixed latency and speed. So TCP/IP is really poor for wireless, especially outdoor wireless like mobile. The ultimate "wireless" is satellite. It doesn't bother with TCP/IP at all. Best to imagine each end of two way link is a pair of proxy servers with a special protocol between them. That's why a VPN is garbage performance on Satellite unless the satellite ISP has your VPN endpoint in your modem and recreating the VPN at their Groundstation.
This is why 4G stuck with TCP/IP, though really a poor solution for mobile, as without being more clever than the Satellite modem folks, lots would be broken.
So this is really ONLY about mobile and how to have not TCP/IP over the wireless transparently to all existing traffic. Look at IP V6. Is the end user or average business going to change to an alternative to TCP/IP?
Anyone today can do their own design of TCP/IP implementation on their OS (virtualised, cloudy or not) as long as to the external network port that it meets the spec!
[* DSL, VDSL etc and other schemes over Cat 3 (phone wires) is more like Radio than cable or fibre. Unlike actual outdoor Mobile, the latency and link speed is constant for a given pair of wires, but the packet loss / interference issues can be like WiFi or Mobile. A powerline Ethernet adaptor or electric fence can disrupt DSL]
