Content-centric Networking for Edge-based Internet Services: a Systematic Literature Review of Scalability, Security, and Quality of Service (2020–2026)
Content-Centric Networking (CCN), together with the wider family of Information-Centric Networking (ICN) and Named Data Networking (NDN), reorganizes communication around named content rather than host addresses, an approach that aligns naturally with the distributed, latency-sensitive character of edge computing. This paper reports the protocol and instrumentation of a systematic literature review examining how CCN supports edge-based Internet services along three intertwined dimensions, scalability, security, and quality of service, across peer-reviewed work published between 2020 and 2026. Guided by the PRISMA 2020 statement, the review specifies a reproducible search across six databases, transparent inclusion and exclusion criteria, a structured data-extraction form, a methodological quality-appraisal rubric, and a thematic coding scheme aligned to four research questions. The Introduction and Methodology are presented in IMRaD form, and the complete research instrument is supplied. The design privileges analytical transparency, replicability, and interpretive depth over aggregate effect estimation
