content centric networking for secu.pptx
- 1. Central University of Kashmir Department of Information and Technology Content Centric Networking Presented by :- Asif Ahmad Najar Enroll: 2102-CUKmr-10
- 2. Table of Contents Motivation Content Centric Networking Model Framework Evaluation Summary and Future work
- 3. Content Oriented Communications Content generated has increased over time Most communications relate to retrieving information Majority use is moving content Solution – use of Information Centric Networks (ICN)
- 4. Necessity of CNN Model Framework Importance of information C entric Networks(ICN) Many architectures IETF involvement (ICNRG) Many standards, proposed standards Accepted architecture – Content Centric Networking(CCN) Named Data Networking(NDN) is a derivative CCN Why a Model framework? 2019 IETF standardized CCN 2 Experimental RFCs –RFc8569, RFC8609
- 5. Architecture Focus of CCN Named hosts to named content (clean slate solution) Focused on caching and forwarding secure content
- 6. Operations • Basic information – Data pull type architecture – request and response – Interest & Content Object • Forwarding – Pending Interest Table(PIT) keeps pending requests – Forwarding information Base (FIB) lists where to forward requests – Content Store (CS) stores received content – Faces are interfaces (link technologies or applications) • Link – Can overlay any transport technology or link technology
- 7. Node Architecture and Layer Models Applications ContentDownloadApp- application to download content ContentServerApp-application to serve hosted content PreficAdvertiser-content prefix dissemination protocol
- 8. Node Architecture and Layer Models -Forwarding RFC8569Forwarder- Implements forwarding as in RFC8569 -Transports Wired Transport-handles wired connections(faces) Wireless Trasport-handles wireless connections(faces) -Mobility INET based mobility models Numen Global information of a node
- 9. Summary and Future work Content orientation of communications -Internet is used to move content -CCN for named content, instead of named hosts Importance of CCN IETF standardization-recent RFCs Future work Immediate- caching policies, prefix dissemination Long-term-operate in intermittently connected network, sensor networks, vehicular networks.
