Outline High Leverage Network-What is It? Application Innovations Enabling a Web 3.0 World: • Network-Aware Application Enablement • Content Centric Networking • Energy Use in Networks • Energy Efficient Routing
Invent, analyze, and build disruptive technologies – related to distributed communications and computing infrastructures – that provide a superior foundation for advanced networking products and services. What is Service Infrastructure? • Areas traditionally considered to defineService 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. ServiceInfrastructure Applications Infrastructure Networking *Session Initiation Protocol Realtime Streaming Protocol Next Gen Network Hypertext Transfer Protocol Realtime Transport Protocol Simple Object Access Protocol IP Multimedia Subsystem Advanced IMS Extensible Markup Language

Space Airborne Maneuver UnattendedGround 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 Connection failure Jamming attack Battle Group Command Center (BGCC) Battln B’s pos?Try: 1.3.2.2 1.3.2.2 End-to-end connectivity Battln B’s pos?Try: 1.3.2.2 1.2.3.4 Sensor reading: Try: 1.2.3.4 Battalion A Battalion B Situation-awarenessdata gathering Sensors
Space Airborne Battle Group Command Center (BGCC) Maneuver Battalion B UnattendedGround Sensors 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 Jamming attack Battln-B/pos Battln-A/sensor Content-centric networking Battln-B/pos Battln-A/sensor Battalion A Situation-awarenessdata gathering
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
Total Backbone Internet Video Wireless Data P2P Wireless Voice Traffic (North America) Energy Efficient Networking
Energy Use: Baseline Trends • State-of-the-art technology evolution • Mix of legacy equipment makes picture worse • Fixed access benefit from ‘old’ optical technology • Wireless data is rapidly growing problem today • Historical energy distribution from edge to core may change over next decade
Lower Higher Degree of Difficulty: Concepts to be Developed Mobile Access: Ultra-efficient power amplifiers Active antennas Small cells Self organizing networks Network MIMO Fixed Access: Cost-reduced FTTH/N Green PON (from ~16W/user to ~5W/user) Metro/Core: Mesh protection / fast restoration Dynamic Optical Bypass Other: Passive cooling everywhere Dynamic energy usage (proportional to load) Network Virtualization and Energy Eff Routing

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
