How this entity was disambiguated

This entity first appeared as the object of triple T8918702 — 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: Routing Policy Specification Language
Context triple: [Internet Routing Registry, usesLanguage, Routing Policy Specification Language]

A. RSVP-TE
RSVP-TE is a signaling protocol used in MPLS networks to establish and manage traffic-engineered label-switched paths with specific resource and QoS constraints.
B. RFC 4271
RFC 4271 is the core Internet standards document that specifies the Border Gateway Protocol version 4 (BGP-4), which governs inter-domain routing between autonomous systems.
C. BGP
BGP (Border Gateway Protocol) is the primary inter-domain routing protocol used to exchange routing information and determine paths between autonomous systems on the global Internet.
D. BGP-4+
BGP-4+ is an enhanced version of the Border Gateway Protocol designed to support routing for IPv6 networks.
E. Routing Table Maintenance Protocol
Routing Table Maintenance Protocol is a network protocol used in AppleTalk to exchange and update routing information between routers.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
