MPLS
E171412
MPLS (Multiprotocol Label Switching) is a high-performance routing technique that directs data through a network using short path labels instead of long network addresses, enabling efficient traffic engineering and VPN services.

How this entity was disambiguated
This entity first appeared as the object of triple T1503371 — 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.

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: MPLS Description of subject: MPLS (Multiprotocol Label Switching) is a high-performance routing technique that directs data through a network using short path labels instead of long network addresses, enabling efficient traffic engineering and VPN services.
