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 newgeneration 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-on- demand (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-per- subscriber 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.

•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.
