-
A.
PDCP
PDCP (Packet Data Convergence Protocol) is a key LTE/E-UTRAN layer responsible for header compression, security (ciphering and integrity), and in-sequence delivery of user and control plane data between the radio network and the core.
-
B.
MPLS
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.
-
C.
ARP (Allocation and Retention Priority)
ARP (Allocation and Retention Priority) is a mobile network quality-of-service parameter that determines the priority for allocating and retaining radio and core network resources, especially under congestion conditions.
-
D.
Link Control Protocol for PPP
Link Control Protocol for PPP is a core component of the Point-to-Point Protocol that negotiates and configures data-link connection parameters between two network nodes.
-
E.
LSP PDU
LSP PDU (Link State PDU) is a type of routing protocol message used in link-state routing, particularly in IS-IS, to distribute information about network topology among routers.
- 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: MPA (Marker PDU Aligned framing) Description of subject: MPA (Marker PDU Aligned framing) is a protocol that enables reliable, in-order transport of RDMA traffic over TCP by framing and aligning protocol data units for iWARP.
