9P network protocol

Target entity: 9P network protocol
Context triple: [Plan 9 from Bell Labs, keyConcept, 9P network protocol]

• A. IEEE 802.19
  IEEE 802.19 is an IEEE working group that develops standards and guidelines to ensure effective coexistence and interference management among wireless networks operating in shared or adjacent frequency bands.
• B. NPN (Next Protocol Negotiation)
  NPN (Next Protocol Negotiation) is a now-deprecated TLS extension that allowed a client and server to agree on which application-layer protocol (such as SPDY or HTTP/2) to use over a secure connection.
• C. PULSE network
  PULSE network is a major U.S. electronic funds transfer and debit payment network widely used for ATM and point-of-sale transactions.
• D. 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.
• E. IEEE 1901
  IEEE 1901 is an international standard that defines high-speed broadband communication over power lines, enabling data transmission for applications like home networking and smart grid systems.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: 9P network protocol
Target entity description: The 9P network protocol is a lightweight, file-oriented protocol from the Plan 9 operating system that unifies access to files, devices, and services across local and distributed environments.
