a) Service Classification

Source: Alcatel-Lucent

b) Service Aware Aggregation and Transport

a) Classifying Services reduced the need for transport resources

b) Service aware transport increases Active users: more Revenue at no additional Cost

c) Leveraging the install base transforming the network packet avoiding double investment


What is driving the change? Conclusion : The game has changed

Explosive demand for new services and applications… – … the traffic mix is changing – … new 4G networking architectures – … existing model is not sustainable – … IP and Ethernet begin to dominate and Fiber in Access will reign

Compelling factors for backhauling network evolution

Technology: IP base stations

Fiber/Ethernet/IP transformation of transport network

Compelling events for

backhaul network

evolution

End-user experience: QoS

Business: total cost of ownership

Capacity: broadband access


… and their

Business

Impact

Transition to new

generation network needs

to overcome a number of

challenges to take full

advantage of packet

backhauling

OPEX Cost Reductions

Enhanced revenue

generation capabilities

Cost effective evolution

from current network

Solution to Operators Challenges

• Ability to go for a gradual transition (IP transformation can’t happen overnight!…)

• Secure end-users QoS satisfaction

• Avoid existing mobile services’ disruption

• Get CAPEX and OPEX advantages from day one

• Simplify operations

Adopt Fiber as backhaul technology

• Secure full interoperability of new network elements with existing architecture and other providers’ networks, including not cellular

• Acquire new technology knowledge

Addressing Operator challenges with Ethernet/IP/Fiber transformation

• Need simple “migration factory” to move existing circuits to the renovated network


Leverage Residential

Infrastructure to Deliver

Mobile Backhaul with

Flexible Last Mile

Access Options

• Benefits: • Opportunity to leverage Fiber for

Mobile backhaul • High capacity backhaul at lower cost

than traditional services • Superior QoS to ensure delay and jitter

requirements exceeded • Solution to provide the clock reference

to base stations for its synchronisation

FTTH improves the Business Case

All backhauled voice and data services over converged IP/Ethernet network.

• Optical fiber is the ultimate backhaul medium from a bandwidth and reliability perspective

• Of the fiber-based solutions, PON is the most cost-effective, having already hit the cost points for residential broadband

• Passive network • Networks are not homogeneous

• Technology and business models are changing

• Incremental cost per home

• CO consolidation

• Don’t lock into technology or deployment type

•To reach everybody you will need flexibility

• Design your network so that you can change it easily
