Alcatel-Lucent 7750
Service Router
The Alcatel-Lucent 7750 Service Router (SR) is the industry’s first service router designed
and optimized for the delivery of high-performance carrier data, voice and video services.
The Alcatel-Lucent 7750 Service Router was designed with system characteristics, routing
and service capabilities that have made it the platform of choice in more than 50 new-
generation service infrastructure rollouts.

The Changing Service Landscape —
Rethinking the Service Delivery Architecture
The Alcatel-Lucent 7750 SR functions as
both a powerful router and a flexible service
delivery platform, and integrates with the
Alcatel-Lucent 5620 Service Aware Manager
(SAM) to deliver efficient and streamlined
provisioning, management and billing for
Internet protocol (IP)/multiprotocol label
switching (MPLS) networks.
Global service providers are preparing for the
next wave of residential and business service
deployments. They understand that in order
to be successful they need a service delivery
infrastructure that offers more bandwidth,
delivered flexibly and reliably to more
customers simultaneously, with increased
service level guarantees.
Service providers are increasingly called upon
to offer personalized voice video and data
services that recognize the unique needs of
individual users; that are, in other words, more
“user-centric.” While the past few years have
seen a focus on network and service convergence with an emphasis on killer applications
delivered over a single infrastructure, the
paradigm has shifted to a user-centric focus
that embraces the demand for a customized
and media-rich user experience across multiple
access methods and across applications.
• For the residential market, the need to
deliver broadcast TV and video-ondemand (VoD) services that meet high
service level agreement (SLA) standards
has introduced an inflection point that
has pushed network service providers to
profoundly rethink their service delivery
architectures. High-speed Internet (HSI)
infrastructures were built around inefficient
business models that focused on cost-persubscriber considerations and allowed for
significant oversubscription and service
level leniency. New high-SLA voice and
video applications have very stringent
availability, system characteristics, quality
of service (QoS), multicast and service
requirements. Those requirements can only
be cost-effectively addressed by rethinking
the overall service delivery infrastructure.

Converged IP/MPLS Infrastructure
• In the enterprise space, new managed data
services — such as virtual private LAN
service (VPLS), IP virtual private networks
(IP-VPNs) and multiservice transit applications using pseudowires (PWs) over a
variety of access methods (frame relay
[FR], asynchronous transfer mode [ATM],
Ethernet, high-level data link control
[HDLC]/point-to-point protocol [PPP],
etc.) — allow service providers to attract
and retain a wider customer base at a lower
cost through converged and more reliable
IP/MPLS service infrastructures. In turn,

end-user customers benefit from a wider
variety of service offerings, increased
service flexibility and accelerated service
activation.
With the Alcatel-Lucent 7750 SR, service
providers are able to build a new type of
cost-optimized highly-available and featurerich service delivery infrastructure that can
seamlessly scale to address both residential
and managed data service market needs,
while delivering significant economies of
scale, skill and scope.

A New Class of Platform
The Alcatel-Lucent 7750 SR platform
provides purpose-built, highly available
software and hardware architectures that
allow network operators to “right-size” their
service infrastructure buildout. The 7750 SR
provides the necessary built-in services
capabilities and packet processing headroom
to allow service providers to scale service
instances, subscriber count and bandwidth
without incurring exponential capital or
operating expenditures (CAPEX or OPEX).
The critical features and functions that
differentiate the Alcatel-Lucent 7750 SR
from a typical Internet-era edge router are
the system characteristics (delay/jitter) and
service-related capabilities that were tightly
integrated into the product architecture at
inception.
The change from traditional best-effort Internet
routing and enterprise switching to true service
routing is not an incremental step — it is a
radical advancement that has required a complete
rethinking of the product architecture and design
at inception. This inflection point is where the
Alcatel-Lucent 7750 SR has established a
leadership position.
An Industry First
The challenges that service providers are
facing have evolved from addressing rampant
bandwidth growth for Internet traffic to
enabling cost-optimized and highly resilient
service delivery infrastructures that can scale
and ensure profitability while minimizing
the overall deployment risk in the long run.
Existing Internet-era routers and enterprise
switches were designed five to eight years ago
to handle bandwidth growth for best-effort
traffic. These platforms were not optimized
for new-generation service infrastructure
rollouts, as they are limited by their system
characteristics (delay/jitter, packet re-ordering
and loss) and their inability to scale services
across all dimensions (number of interfaces,
bandwidth, service instances and policies,
performance level, etc.).
Similarly, so-called IP service platforms
have appeared on the market, but they were
designed and optimized for low-speed, besteffort consumer services (mass-market digital
subscriber line [DSL] for residential service).
They do not have the high-availability,
scalability or service capabilities that will
allow them to cost-effectively enable largescale (tens of millions of customers), highspeed data, voice and video service rollouts.
