Re: [gaia] draft-irtf-gaia-alternative-network-deployments. Stephen Farrel's comment #1. DTN

Hi,

Thanks a lot for the information.

The questions are:

- Where could DTNs fit in the draft? "Technologies employed" section? https://tools.ietf.org/html/draft-irtf-gaia-alternative-network-deployments-04#section-6

- Are these efforts only experimental or are being used in operational environments?

Thanks,

Jose
