Networking
What is Service Infrastructure?
Areas traditionally considered to define
Service Infrastructure:
Application-level protocols (e.g. SIP*,HTTP, SOAP/XML, RTP, RTSP),
Communication Architectures andMiddleware (e.g. IMS, A-IMS, NGN),
Network Overlays,
Cross-Domain Service Blending,
Cloud Computing,
Content Distribution & Delivery,
Messaging.
Invent, analyze, and build disruptive technologies – related to distributed communications and computing infrastructures – that
provide a superior foundation for advanced networking products and services.

Information Access in Today’s Network
Today’s network: host-oriented data access
Always assume end-to-end connectivity: content source requester
Only knows finding/authenticating data according to the content source

Content Centric Networking
Simple, unified, flexible communication architecture
Data is requested by name using any means available
Any node that hears the request with a valid copy of the data can respond
The returned data is signed, and optionally secured

Content Centric Networking
Key design philosophy
Data has a name, not a location
Improved data availability using data replication
Robust to node mobility/failure, network failure, attacks
Integrity and trust are derived from the data, not the channel it arrives on
Anything that moves bits in time or space can and will be used to communicate
Data access is not limited by network topology (or end-to-end connectivity)
CCN removes many layers of management infrastructure

Efficient/robust data access
Energy efficient content delivery in wireless networks:
TODAY: one has to go through long-range wireless comms (3G, LTE)
Even if one can get the same data from one’s neighbors using Bluetooth
CCN: given named content, chooses an energy efficient interface

Summary and Conclusions
The High Leverage Network is the basic strategic direction that ALU has chosen for its future.
Networking technologies in support of the HLN are evolving with fundamental new concepts such as CCN. At the end of the day, these may be more important than the physical layer technologies in terms of their impact on the web and how we will communicate using it.
Together They are Enabling a World of Ubiquitous Communications
Anywhere, Anytime
Realize the Dream of Broadband Access to Everyone in an Energy Efficient Way
