Named Data Networking
- 1. Named Data Networking Mustafa Cantürk Murat Can Sayılgan
- 2. Named Data Networking Content Centric Networking By Van Jacobson At PARC www.ccnx.org
- 3. A trending topic: one idea, many names Content Centric Networking Named Data Networking Information Centric Networking Data Oriented architecture
- 4. Named Data Networking Funded by NSF (National Science Foundation) At first, forked CCN code Then… They rewrite code from scratch
- 5. NDN Testbed
- 6. NDN Testbed
- 7. Main Ideas
- 8. Main Idea Naming data/content instead of hosts Data will be addressed like URL (name) itu.edu.tr/computer_comm/ndn.pptx Routers will operate on names, not IP’s No client-server model It is a client-cloud model Model is based on data itself
- 9. Request-Response Mechanism Client’s doesn’t connect to a host Client send interest packet to router Router finds the data And replies to client
- 10. IP Networking (Host based model) NDN Networking (Cloud model) Network Model
- 11. Main Idea
- 13. Node Model
- 14. Node Model
- 27. NDN Routers Work to verify data More state in its routing entries, stateful More complex entries (names vs IP addresses) Associated storage devices Increased cost
- 28. NDN Applications and Implementation No TCP or UDP No ports Applications have to change their own network stack There are some PoC applications NDN can work on UDP/IP overlay IP can work on NDN overlay IP and NDN both work hybrid on transition phase IP protocol started working over telephone network
- 29. Security HMAC for data integrity SDSI for authenticity and data privacy Distributed key management mechanism Keys are mapped to identities via namespaces
- 30. Advantages No DNS - IP conversion Wipes unnecessary network stacks Not connection based Multiple interfaces can work together for a single request Efficient bandwidth usage Mobility friendly No connection loss when moving Data/Object oriented architecture (Not programming paradigm) Works with «named objects»
- 31. Advantages (cont.) Easy administration No spanning tree DoS and DDoS are hard to implement
