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

Break through the layered architecture, creating infrastructure elements
that intertwine network knowledge and application knowledge
to tame the onslaught of content, devices, and service complexity.

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

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
