Re: [DMM] User Plane Protocol Study in 3GPP
Uma, I’m happy to hear that from you. I was just afraid that some vendors are trying to sell NAPT traversal cellular boxes with additional license fee. As you all know, 5G radio requires us to deploy APs much dense that we expect several or many IPv4 10/8 and even 100.64/10 should be required to cover the footprint of operators. What I imagined was if a business person in a vendor finds that hidden bottleneck, I expected that the guy proposes NAPT traversal products to his company and easily convinced to get the go sign. I have to admit that he/she must be a smart business person. If a operator who fully depends on IPv4 as backhaul/core transport, I expect that the operator couldn't resist to that attractive proposal. I hope you don’t do that even after you know my imagination.

Re: [DMM] User Plane Protocol Study in 3GPP
Hello Uma, let me clarify something. Are you proposing that we need to work on mobile user plane protocol with IPv4 NAPT? Or, does your employer plan to develop NAPT traversal cellular equipments and application gateway for the user plane protocol? It seems reinvent of PPTP.
