What is done so far
Problems with current internet
- security
- control, mgmt and data planes are intermixed
- control msgs are piggybacked with data packets
- mobility
- identity and location in one (IP address) makes mobility complex
- energy
- assumes live and awake end systems
- communication can happen only when both ends are awake
- no explicit support for client-server traffic and distributed services

Architectural Principles of NDN
- differences between IP and NDN
- security is inbuilt in NDN
- IP is host centric, everything is around host (IP), IP is in center
- to access a service, u use URL which is a user defined name for IP address
- in NDN, there is no IP, everything is centered to contents only
- my requirement is I need some content
- in place of IP, I will have name of content
- there is no need to give address, identification to a device
- rest things are same
- multiple applications
- multiple types of connectivity
- NDN Project
- current client server model facing challenges in supporting secure content oriented functionality
- n/w is transparent and just f/wing the data
- moving from end to end packet delivery from Content Centric Model
- focusing on WHAT instead of WHERE (content vs address)
- allows content caching on n/w side to optimize the traffic
- content distribution is inherent in architecture
