Hi Fred, I read the draft but still need to see the interest/solution in disaster_scenarios, which your assumption was not clear to me, as we using 5G network/cells or only MANETs, I think your use case is using the internet of wireless_terrestrial_network/5G_network, so I don't think we can say MANET of MANETs, because the 5G network already is using its management protocols and routing protocols that are different to MANET. Or please explain from where some of the cell phones/router are getting the internet service? I think the draft needs to identify the terrestrial network as use cases, IMHO to make it general will never help.

The internet provider's net should not be considered as MANET, usually that internet is the wireless infrastructure_terrestrial_network, and not MANET of MANETs. Usually our MANET is at the layer 3 or 4. > The MANET Internetworking > service should then support interconnection of MANETs using the Internet as > transit based on virtual circuits established on-demand as an adaptation > layer function. > ok so do you mean that is at layer 4 ? we need to be clear to determine the service access point. > So, the Internet would serve as a massive transit network for connecting > small-to-modest sized MANETs on demand.
