1 ABSTRACTDriven by the latest innovations in internet-based services and multi-media enabled
TVs, PDAs and smartphones, consumers are once again fueling change in the network
services industry. Whether its mobile subscribers consuming more applications and
video content while on the road, residential customers demanding more personalized,
on-demand video services, or enterprises looking to fully leverage the efficiencies of
cloud computing, service providers (SPs) are faced with both the challenge - and the
opportunity of evolving their services to meet the changing needs of their customers.
The opportunity is substantial. The market for public cloud-based services is expected
to reach $176.8 billion by 2015*. PayTV services have already reached $200 billion
annually and are experiencing healthy growth despite the recent economic downturn.
The extent to which SPs can transform these opportunities into new revenue streams will
often hinge on their ability to overcome the challenges at the IP edge of the networks
that stand in the way of service evolution. Maximum return mandates an IP edge with
the flexibility, scale and operational efficiency to capitalize on new service opportunities
while keeping rising bandwidth costs under control.
Many SPs have embarked on their service evolution journey and are driving new revenuein a profitable manner with the Alcatel-Lucent 7750 Service Router (SR) at the edge of
their IP network. The 7750 SR allows SPs to:
Diversify their network services portfolio with new or extended services
Deliver more bandwidth more efciently to meet growing demand
Distinguish their services from the competition
Drive operational efciency and OPEX reduction
Targeted to SP product marketing, network architecture and network operations execu-
tives, this document provides an overview of changing enterprise and consumer needs,
the new opportunities now open to SPs and the transformation challenges they face,and how these challenges and opportunities are best addressed with an IP services edge
based on the 7750 SR.

2 SERVICE EVOLUTION DRIVERS &OPPORTUNITIES2.1 External innovation driving service evolution
When the first network services were introduced decades ago, the innovation cycle was
driven by the service providers themselves they defined connectivity services, brought
them to market and added incremental enhancements along the way. In the past decade,
technology innovations outside the domain of the service provider - in internet-basedservices and in personal computing devices have turned this model upside-down and
changed how subscribers view and consume connectivity services. To re-establish their
central role in the new network-based service value chain, SPs must evolve their services
to meet the changing needs of their customers as they embrace the best of what technol-
ogy innovation has to offer.
2.2 Residential service trends & opportunities
In the residential broadband services domain, the catalyst for service evolution is video,
which is set to permeate every aspect of a subscribers online experience. Driven by the
freedom and exibility of video on demand (VoD) services delivered over-the-top (OTT),
the high quality viewing experience delivered by managed IPTV services, and an explo-sion in consumer electronics devices (ie, tablets, internet-enabled TVs) that consume
content, subscribers are demanding a more flexible and personalized broadband experi-
ence, one in which they can consume any content on any device, anytime, anywhere.
While at rate usage caps can be effective in minimizing the impact of surging OTT VoD
bandwidth on the network, SPs can thrive in the video-dominated era of high bandwidth
services by enriching their current lineup of voice, High-speed Internet (HSI) and linear
IPTV services with (see Figure 1):
VoD services with guaranteed QoS levels
Enhanced linear TV services with high video quality and fast channel change capability
HSI plans with application-aware metering capability to personalize the service
experience, Application-aware zero rating and usage based billing to monetize OTT trafc and
ensure fair share use
Wi-Fi access that seamlessly extends the home connectivity experience out into the
community and beyond

2.3 BUSINESS SERVICE TRENDS &OPPORTUNITIESIn business services, the catalyst is cloud computing, storage and applications. Enterprise
demands for increased flexibility and operational efficiency have spawned whole
new industries around areas including application hosting and software-as-a-service.
However, issues such as loss of visibility and control, and lingering concerns over the
security and performance of cloud-based applications are dampening enterprise adoptionof these services. At the same time, margins in traditional connectivity services such as
VPNs and business internet are shrinking as universal availability transforms them into
a commodity.
SPs can thrive in this new cloud-dominated era of business services by leveraging their
strengths in building highly reliable networks to become the go-to-choice for enterprises
headed to the cloud. They can evolve their business service portfolios to include (see
figure 2):
Cloud Access VPNs and Business Internet services that restore application visibility
and control to enterprise IT managers
Network-based Distributed Denial of Service (DDoS) mitigation services that eliminatepotential threats before they can impact enterprise customers and the cloud data
centers they rely on
End to-end SLAs that guarantee performance for applications hosted in the SP data
center and delivered by the SP network
Rapid service provisioning for cloud VPN access
Figure 2: Business service opportunities
2.4 Mobile service trends & opportunities
In mobile, a new generation of smartphones and portable computing devices is rapidly
changing the previously predictable networks of mobile providers. As bandwidth utiliza-
tion and related signalization surges, wider spectral bands used in LTE are bringing
bandwidth efficiencies, but they do not replace lost voice and SMS revenues, or provide

a way to monetize the ever increasing flow of traffic. SPs can increase ARPU and service
profitability through (see figure 3):
Personalized, application-aware service plans that allow subscribers to make the best
of available bandwidth while monetizing OTT trafc
Value-added video distribution capabilities such as adaptive, high-quality streaming
enabled by integrated service intelligence
Higher capacity mobile packet core that can accommodate more subscribers and
bandwidth more efficiently Wi-Fi access networks that move trafc off the radio network to provide a seamless
higher-bandwidth connectivity experience
Figure 3: Mobile service opportunities
3 SERVICE EVOLUTION CHALLENGESMany of the challenges SPs must overcome to ensure successful service evolution are
centered at the point in the network where service policies are implemented at the IP
edge. Chief among these are scale and performance, enabling differentiation and servicerichness, and reducing high operational complexity
and cost.
3.1 Scale & performance
The surging tide of bandwidth has surpassed the performance capabilities of legacy edge
routers. Centralized packet processing architectures are buckling under the load, and
technology limitations in commercial or off-the-shelf routing silicon are forcing provid-
ers to trade off raw capacity for feature processing. Surging bandwidth is also creating
bottlenecks at centralized IP edge routers, limiting service availability and scale.
In residential, video transport costs are escalating with the proliferation of per-subscribervideo on demand sessions. Each session must traverse the entire network to reach the
initiating subscriber, consuming bandwidth along the way, and creating congestion at
performance-limited IP edge routers. Centralized content injection and edge routers
designed for yesterdays internet speeds no longer make economic sense.
Business networks have similar issues as enterprise adoption of video communications
and cloud-based client/server applications are taxing PE routers and limiting the cycles
available for new services.

techniques are resulting in higher bandwidth utilization, and a much higher traffic
burden at the mobile packet core (MPC). Performance is also an issue: as more
internet-capable devices, from tables to smart-phones, tap into the mobile network, the
performance burden on the MPC which is responsible for processing their mobile IP
connections also increases.
3.2 Differentiation & service richness
The most effective way for SPs to achieve sustainable differentiation for their services whether its enhancing VPNs to resolve cloud migration issues, or providing a higher
quality video experience is to add high touch packet processing capability in the data
path. Traditional edge routers often lack this capability outright, or they lack the perfor-
mance and scale to support large-scale or high bandwidth deployments. To compensate,
some SPs have deployed specialized appliances at the edge of their network and in CPE
locations. While this approach allows for some differentiation, it requires SPs to deploy
and maintain multiple platforms and hundreds of additional nodes and linkages. This
greatly increases operational complexity while reducing service scale and reliability.
Feature consistency across a diverse set of platforms is difficult to achieve, limiting an
SPs ability to differentiate where it matters most in providing a consistent quality of
experience to customers that consume multiple services.
3.3 Operational complexity
Traditional IP edge routers were single-purpose devices targeted for specific mobile,
residential or business services. This fragmented approach to product development has
resulted in a similarly fragmented IP edge infrastructure. It is not uncommon to have
separate edge routers for IPTV services, HSI services, Ethernet VPNs, IP VPNs and busi-
ness internet services - all configured as overlays over the same aggregation and access
networks. Mobile networks are also commonly fragmented, with a separate mobile
packet cores to aggregate 2G, 3G, LTE and Wi-Fi access networks and to offer IP-based
services.
The operational impact of this siloed approach to service deployment is massive. SPs
must deal with the operational complexity of maintaining multiple service networks,
certifying and maintaining multiple router operating systems, and providing their custom-
ers with a consistent experience across all their disparate service offerings. Delivery of
new services and enhancements to existing services, is a slow, complex affair. Service
integration and blending such as providing IPTV content through an HSI service is
difficult to achieve as, as is network capacity planning across services based on sub-
scriber requirements.
The rapid growth of internet-ready personal computing and M2M devices has trans-
formed IPv6 migration from a future consideration to a pressing reality for both business
and consumer networks. SPs must grapple with the operational complexity of how togrow the network when there are no new public IPv4 addresses available, and how
to transition to IPv6 while maintaining IPv4 continuity for applications, networks and
services that may not be ready to make the change. IPv6 migration is also compounding
scale and performance issues by adding yet another processing hurdle for legacy edge
routers already straining under the load.

4.3 Integrated intelligence
Service providers looking for a future-proof approach to differentiate their services can
leverage the 7705 SRs multi-service integrated service adapter (MS-ISA) to introduce
high touch processing to the common edge platform (see figure 5). MS-ISA application
and subscriber aware monitoring and control capabilities allow residential and mobile
providers to create personalized service plans that are optimized for individual consumer
needs. IPTV services can be revitalized to stand apart from the competition via fast chan-
nel change, or higher quality video delivery. Mobile video sessions can be intercepted tosupport automatic transcoding via specialized appliances, or to provide upgraded quality
of service. For differentiated business services, MS-ISA allows enterprise customers to
monitor and control their cloud and enterprise applications, without the expense of a
large-scale appliance rollout. New revenue streams in secure network and cloud services
are enabled by adding DDoS protection capability to any service, at any point in the IP
network.
Figure 5: Service differentiation with the MS-ISA
4.4 Greater operational efficiency
The ability to drive operational savings is built into all aspects of the 7750 SR network.A common management platform for services, network elements and applications
allows SPs to reduce service provisioning times by up to 97% and virtually eliminates
provisioning errors during reconguration. Integration of new services into IT and OSS/
BSS systems is greatly simplied, accelerating time-to-market for new services. Integrated
service intelligence enables additional operational savings by allowing SPs to optimize
their networks through application-level trend analysis, or by extending IPv4 address
continuity through carrier-grade NAT translation. A recent study by Bell Labs identied
multiple operational benefits obtainable via the convergence capabilities of 7750 SR,
including streamlined sparing, training, repairs, and OSS integration. Integration of
business and residential services on a common IP services edge resulted in 60% OPEX
savings (see figure 6).

Figure 6: OPEX savings via residential and business service convergence on the 7750 SR
(Source: Alcatel-Lucent)
The ability to distribute service intelligence - such as application monitoring, policy
enforcement, and caching right to the edge of the network provides the highest quality
of service for customers, and the greatest operational savings for carriers. In a distrib-
uted architecture, subscriber management, content caches and high touch processing
capabilities move to the edge of the network, closer to the customer. By distributing
service intelligence to the edge, SPs can provision more bandwidth and fewer subscribers
per GE port to accommodate the growth of video and other high bandwidth services.
Video on demand sessions are initiated closer to the subscriber and no longer traverse
the entire IP network (see figure 7). This has the dual benefit of enabling long term scale
and lower cost per bit for video transport. Since VoD content delivered by the SP has a
much shorter distance to travel vs content from internet-based OTT vendors, SPs can alsooffer signicantly higher service quality and performance vs OTT offerings.

A large global tier 1 provider selected the 7750 SR to provide the flexibility, scale and
operational efficiency they required to remain at the cutting edge of service innovation as
they converged multiple networks into one (see gure 8). The 7750 SR supports Ethernet
VPN, IP VPN and residential services on a common platform to maximize operational
savings and enable a consistent customer experience across services. Distribution of thesubscriber management and business VPN functions closer to their customers allows the
provider to increase operational savings while enabling even greater flexibility and scale.

5.2 National Tier 1 Provider (EMEA)
A national tier 1 provider selected the 7750 SR to drive the strategic transformation of
their network to support concurrent delivery of multiple IP-based services, including
new HD video services, to mobile and residential customers (see figure 9). Key require-
ments included line rate IPV6 support to 100Gb/s, and high availability service deliveryplatform that would allow them to offer always-on services. The ability to integrate
mobile backhaul of cell site routers de-risked the service transformation process as
mobile backhaul became just another IP service on a common IP service platform.
