How this entity was disambiguated

This entity first appeared as the object of triple T5768071 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: RFC 5389
Context triple: [RFC 5766, updates, RFC 5389]

A. RFC 3551
RFC 3551 is an IETF standard that specifies the audio and video profile for the Real-time Transport Protocol (RTP), including default payload formats and parameter assignments for real-time multimedia communication.
B. RFC 2570
RFC 2570 is an Internet standards document that updates and replaces earlier SNMP-related specifications, refining the framework for network management using the Simple Network Management Protocol.
C. RFC 4251
RFC 4251 is the core specification that defines the architecture and protocol framework of the Secure Shell (SSH) protocol used for secure remote communication.
D. RFC 5766
RFC 5766 is an IETF specification that defines the Traversal Using Relays around NAT (TURN) protocol for relaying network traffic to help clients communicate across NATs and firewalls.
E. RFC 5905
RFC 5905 is the Internet standard specification that defines version 4 of the Network Time Protocol (NTP) for synchronizing clocks over packet-switched, variable-latency data networks.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
