How this entity was disambiguated
This entity first appeared as the object of triple T1773970 — 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: Datagram Delivery Protocol Context triple: [AppleTalk, networkLayerProtocol, Datagram Delivery Protocol]
-
A.
UDP
UDP (User Datagram Protocol) is a lightweight, connectionless transport-layer protocol used on the Internet for fast, low-overhead data transmission without guaranteed delivery or ordering.
-
B.
Host-to-Host Protocol
Host-to-Host Protocol was an early ARPANET communication protocol that provided reliable end-to-end data transfer between computers, serving as a precursor to modern transport protocols like TCP.
-
C.
RFC 791
RFC 791 is the foundational Internet standard that specifies the design, structure, and operation of the Internet Protocol version 4 (IPv4).
-
D.
ICMP
ICMP (Internet Control Message Protocol) is a core network-layer protocol used primarily for sending error messages and operational information, such as in tools like ping and traceroute, within IP networks.
-
E.
RFC 768
RFC 768 is the Internet standard that defines the User Datagram Protocol (UDP), a core transport-layer protocol used for low-latency, connectionless data transmission.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Datagram Delivery Protocol Description of subject: Datagram Delivery Protocol is the connectionless network-layer protocol of the AppleTalk suite, responsible for routing and delivering datagram packets between AppleTalk nodes.
