Statement
Delay-tolerant networking is operational in bounded space deployments, including ISS payload services and PACE; that evidence does not establish outcomes in terrestrial challenged-network settings.
Evidence dimensions
- Basis
- observed
- Readiness
- operational
- Confidence
- strong
Assessment rationale
NASA documents bounded operational Bundle Protocol use for ISS payload services and PACE. RFC 9171 standardizes the base protocol but leaves routing selection outside its scope and moves custody outside the base protocol. These facts do not establish beneficial outcomes for disaster response, remote science, rural networks, or disrupted terrestrial infrastructure.

Store-and-forward bundles, disrupted connectivity, mission adoption, testing, and described cross-domain utility. · direct demonstration - RFC 9172: Bundle Protocol Security (opens external site in a new tab)
Security services and processing needed when bundles cross untrusted or intermittently connected nodes. · context only
Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
Comparative field studies measuring useful delivery, energy, storage wear, recovery time, security incidents, accessibility, and cost across the four terrestrial contexts would strengthen or narrow this broad benefit claim.
