Huawei Technologies Canada Huawei Technologies Canada This Internet-Draft provides a gap analysis and applicability statement that maps existing Discovery Mechanisms and protocols to the DAWN problem statement and discovery requirements. The analysis evaluates security, privacy, applicability, flexibility, and suitability of existing standardized, non-standardized, and proposed discovery solutions and protocols to the DAWN problem statement and REQ-DISC corpus. It identifies high priority gaps, proposes mitigations and hybrid patterns, and serves as reference for future prototyping and development. The intention is for this draft to evolve as new solutions come to existence.
