Solution Reference Architecture Overview: Broadband Edge

Residential broadband providers are experiencing explosive bandwidth demand driven by an ever-expanding array of home and mobile applications, especially online video. Increasing bandwidth demand and subscriber expectation for high-quality user experience is challenging service provider business models, as the network investment has outpaced revenue growth. Now, service providers are struggling to decrease operational and capital expenditures while providing the same level of service, and to identify innovative service offerings that will drive new revenue streams. The existing broadband edge architecture is distributed among a variety of routers, switches, and appliances, making management and service creation difficult.

The broadband edge demands a new architecture that can enable a high-quality user experience for subscribers and empower the provider to reduce expenses and drive new, innovative services that can increase average revenue per user (ARPU). The Juniper Networks Broadband Edge Reference Architecture is designed and verified to meet this challenge and improve the economics of the network edge.


The Juniper Networks Broadband Edge solution enables providers to maintain traditional multiplay services with a simpler, collapsed service model that consolidates management and service activation points. The benefits of this approach include faster rollouts of differentiated service offerings and greater operational efficiency, which contribute to higher margins.
