Named Data NetworkingIntroduction and hands on tutorial

by Alex Afanasyev UCLA

Steve DiBenedetto CSU

GEC21

Goals for today

bull Introduce Named Data Networking (NDN)

bull Describe the project and its goals

bull Illustrate NDN concepts

bull Show how to write simple applications and now to experiment with NFD forwarder

Core Idea

Use names directly at the networking level

Focus on data not host-to-host connections

Closed-loop communication

Named Data Networking

bull Leverages the strengths of the Internet addresses weaknesseso Layers efficiently atop Ethernet UDP TCP hellip

bull Naturally accommodateso Mobile deviceso Wireless and other broadcast-based link typeso Data authentication and security privacy anonymityo Policy-based forwarding routing with loops

bull With NDN we aim to show thato Communication is more secureo Infrastructure is more efficiently utilizedo Applications are simpler

Questions

bull Can NDN efficiently support host-to-host patterns

bull Can NDN efficiently support user-specific data and services

bull Can you count clicks and ad impressions in NDN

bull Can you efficiently route all those names

bull Can you scale the forwarding plane

bull Can you prove security and privacy properties

Yes Yes mostly23

Conclusion (12)
