Networking
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.
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
• 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

Telco Virtualization aka Cloud Computing
Today, equipment vendors are selling dedicated, specialized boxes to service providers.
Service providers build their networks from the ground up using dedicated equipment for services (e.g., LTE, IMS).
The hardware running these networks and services is dimensioned to meet the peak demand.
This model requires every service provider to build up the entire network stack and service infrastructure.
Resources need to planned very carefully according to the estimated future maximum demand.
Deployment of new capacity and services is a costly and slow process. Resources cannot be shared across services within a service provider and
across service providers creating inefficiencies.
The goal of Telco Virtualization is to overcome these limitations by enabling service providers to use commodity hardware to run own and hosted services.

Early days of the Web: Application providers owned and operated servers,
applications and managed customers.
Traditional service providers: Own and operate infrastructure,
applications, spectrum, ensure connectivity and manage customer relations.
High initial investment, limited opportunities for changes and expansion.

Classic Web Services: Buy server and network capacity from
Web-hoster. Develop applications and
manage customers. Web-hoster owns and
operates servers.
Development in service provider market: MVNO* provides phone service w/o
owning the infrastructure. Service providers outsource
operation and management of the network to vendors(e.g., Ericsson/Sprint).

Web Services today: Develop applications and deploy
them on a cloud. Add resources on the go. Cloud operator owns and
operates infrastructure.
Telco Virtualization: Minimize specialized hardware to what
is necessary (e.g., DSLAMs, routers, radio towers).
Most Telco services are preformed in software running in clouds on commodity computers.
New services can be hosted on the cloud.

Enabling Telco VirtualizationNew Technology Leads to Market Disruption
Key Disruptions- Telco hardware investment diversifies—buy more shared services and fewer dedicated resources, focused deployment of specialized hardware- Telco investment in software and services increases- New market landscape—new players enter market; holders of specialized and/or shared resources compete with traditional equipment vendors; telcos’ role divided/reduced

Summary and Conclusions
•Remarkable Set of Physical Layer Technologies are being Developed for Web 2.0/3.0 Networks
•However, the Networking Technologies are also Evolving with Fundamental New Concepts such as CCN and Telco Virtualization. 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
