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 conver- gence 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.
