4. Devices/Machines
A bridge between the tangible and virtual worlds
 The vision: 50 Billion connected devices in 2020
 Any tangible device (refrigerator, washing machine, car, etc.)
 Sensors/Actuators: installed, implanted (animals), wearable (humans)
 The mobile phone as a hub for sensors
 RFID

5. Big Data
Devices + Data = Applications
 Everything we do generates data
 2.5 quintillion (2.5*10^18) bytes of data are created daily
 The amount of data in the world doubles every 18 months
 Example data generators: social networks, internet search indexes, call
detail records, astronomy, atmosphere, genomics, military
surveillance, medical records, photography archives, e-commerce
 BIG DATA challenges
 Volume, Velocity, Variety, and Veracity
 Types of data
 Usage data
 Volunteered data
 Data processing
 Mining, analytics – find patterns in data
 Semantics – decode ‘meaning’ of data

6. Cloud
The Cloud makes applications global
 The Cloud enables allocation of compute and storage resources on-demand
 Follow-me cloud: global access, multi access, multi device
 The Cloud runs
 Applications
 Data mining/analytics/semantics
 Network functionality
 Compute/storage offloaded from end-devices
Centralization
Centralized Cloud: Distributed Cloud / Fog
Computing:
- Global Service
- Low-latency
- Large capacity, elasticity applications/content
Distribution
- Ultimate utilization of - Saves networking resources
resources
- Opportunistic
computing, based on available
capabilities of devices/CPEs
flexible apportioning

7. Network
Content Centric Networking
 Move the focus from network nodes to:
 Delivery of content objects
 Delivery of messages to/from devices (Publish-Subscribe)
 The changing relationship between network and services
The network establishes network resources
connectivity, applications Service-aware traffic as building blocks
running steering that can be used to
Over The Top ‘program’ new services

8. The Internet of Things (IoT),
the Internet of Everything (IoE)
Building a networked society
 ‘Things’ will be seamlessly integrated into the information network
 ‘Things’ are expected to become active participants in
business, information and social processes
 Things’ reacting autonomously to ‘real/physical world’ events and
influencing it by triggering actions with or without human intervention
Logical entities:
Persona, Community,
Things
 Streamline everyday tasks, processes Context:
 Automate decision making Ownership, Authorization
, Location
 Tackling life inefficiencies
 Access to covert information
 Better recommendation engines Physical entities:
Human, Machine/Device
/Object

9. Network evolution towards
the ‘New Telecom’
Major directions in Telecom Networks
 Intelligence is moving to the cloud
 Complexity is moving to the edge
 Networks are flattening – from hierarchy to mesh
architecture
 Network architecture convergence
 Networks automation, flexibility

10. Wireless takes it all
Wireless in the frontend, wireline in the backend
 In 2016 wired devices will account for 39% of IP traffic, while Wi-Fi for 51% of IP
traffic and mobile devices for 10% of IP traffic (source: Cisco VNI, May 2012)
 LTE (Long Term Evolution) (3.9G)
 As of Nov 2012, LTE is deployed in 117 networks in 54 countries, with 323
operator commitments (source: 4G Americas, Nov 2012)
 More than 40M subscribers today, projection for 1B LTE subscribers by 2017
(source: Informa Telecoms, June 2012)
 LTE-A (4G) : expected to be commercially available in 2013, with wider
deployments by 2015
 WiFi WiFi WiFi (self deployed, operator deployed, managed WiFi)
 TV White Space – for rural broadband
 Beyond LTE-A (LTE-B, 5G) – Standardization (3GPP release 12 is underway)
 Personal Area Networks
 ZigBee, Bluetooth
 The LTE packet core architecture (EPC) is designed to support both fixed and
mobile access networks and become a common converged core

11. Heterogeneous Networks (Hetnets)
Macro Cell for coverage, Small Cell for capacity
 Higher data rates and increased capacity require denser
infrastructure
 User distribution and traffic density are often non-uniform 
deploy an heterogeneous network (hetnet): hotspot cells in
traffic hotspots
 Hetnet complexities:
 cell density
 interference management
 user-deployed cells
 handled through automation: Self Organizing Networks (SON)

12. Content is pushed to the Edge
 The popularity of content-rich applications and availability of
smart compute-extensive devices, drive content and
applications to the edge
 Storage/caching pushed into network nodes, as close as
possible to end-users; network steering to retrieve content
 In the future – smart terminals will become part of an
opportunistic cloud
 trade-offs between storage/computing/communication
 Currently for optimization of overloaded networks,
performance and QoE guarantee
 In the future – optimization of energy consumption

13. Networks are flattening
Hierarchy is breaking down
 Network flattening is achieved through removal of aggregation
points
 The network is simplified to include two types of connections
 Access to cloud centers (centralized or distributed)
 Inter-connectivity between cloud centers
 Ultimately the network will become a symmetric mesh
 Each entity connected to the network (device/machine/cloud)
can be a content client or a content server

14. Mesh Architectures
Breaking down network’s hierarchical architecture
 Cloud Federation
 Connect between distributed cloud centers to enable access to
content
 Mesh connectivity between base stations
 LTE/LTE-A introduces new spectrum efficiency mechanisms
(e.g., COMP) that involve coordination between base stations.
This calls for mesh connectivity (over x2 interface) between e-
NodeBs
 Device to device (D2D) Communication
 Beyond-LTE standards will probably enable device-to-device
communications
 Useful in scenarios like content sharing with friends in the close
proximity, cognitive cars exchanging road information

15. Network Virtualization:
the network wanders to the cloud
IT-Telecom Convergence
 Network Function Virtualization (NFV) – virtualization of network functions and services
 Motivation: run network functionality over off-the-shelf standard IT infrastructure
 leveraging standard IT virtualization technology to consolidate many network
equipment types onto industry standard high volume servers, switches and
storage
 applicable to any data plane packet processing and control plane function in fixed
and mobile network infrastructures
 Software Defined Networking (SDN) – separation of Network node Control and Data
planes, with an open interface (e.g., OpenFlow) between them
 Motivation: network programmability - turn network resources into building blocks
that can be used to ‘program’ new services
 Intelligence is moved to the cloud, network is simplified and can handle capacity
growth and scale
 Control plane is implemented in software and running in the cloud
 Network nodes specialize in efficient ‘forwarding’ (data plane), will be
commoditized and become cheaper

16. Content/application aware networking
The network receives new roles
 A ‘connectivity’ network will always be there
 The ‘delivery’ network
 Optimized content delivery per user/application
requests
 Message Clearing house (Publish Subscribe)
 Service Orchestration – mashup applications and
data originated in various verticals

17. Telco Operator role
Telcos will be reinventing themselves
 Choose your role!
 Up the value chain or down the value chain
• Bit carrier
Connectivity • Connectivity brokerage services
• Content delivery, message delivery
Delivery • Service Enablement
• Linking content and information into
Service something meaningful
• Localizing a global service
