What is Content centric networking
- 1. CONTENT CENTRIC NETWORKING Simple Definition
- 2. CCN Introduction A trending topic : one idea, many names Content Centric Networking Named Data Networking Information Centric Networking Data Oriented architecture
- 3. Content Centric Networking (CCN): Goals Creating a simple, universal, flexible communication architecture that: Matches today’s communication problems Matches today’s application design patterns Is much more secure Requires far less configuration
- 4. Mathematical concept used: The basic tree structure is used in developing the Content Centric Network
- 5. CCN Node Model There are two CCN packet types: interest and data. Both are encoded in an efficient binary XML. CCN Interest and Data packets - http://named- data.net/project/archoverview/
- 6. Basic description Data is requested by name get ‘/parc.com/van/presentation.pdf’ Any node that hears the request and has a valid copy of the data can respond The returned data is signed, and secured, so its integrity & association with name can be validated (data centric security) Here Is ‘/parc.com/van/presentation.pdf/p1’ <data>
- 11. Content goes only where there’s interest. Total bandwidth is minimized. There’s no routing or control traffic associated with the replicas.http://www.slideshare.net/sokphearin/conte nt-centric-networking
- 12. TCP/IP and CCN Protocol Stacks Replace packets with Data Objects or Interests Replace Addresses with Names of Objects

Related works Data-Oriented Network Architecture (DONA) Almost like CCN, introduces a new network identity called Resource Handler (RH) Uses regular IP Internet Indirection Infrastructure (i3) Based on Distributed Hash Tables Publish-Subscribe Internet Routing Paradigm (PSIRP) Network of Information (NetInf) Uses DHT for name resolution system
- 21. Conclusion Content Centric Network – uses “named content” as its central abstraction rather than host identifiers – retains the simplicity and scalability of IP – offers better security, delivery efficiency – designed to replace IP, but can be incrementally deployed as an overlay
