Product Overview
Broadband operators face many challenges as they offer increasingly complex bundles of multiplay services. The Juniper Networks Broadband Services Router (BSR) portfolio provides the advanced subscriber management, high- performance routing, efficient Ethernet aggregation, and superior quality of service that address diverse broadband network edge requirements with unprecedented capacity, reliability and performance.
Product Description
Our BSR portfolio consists of the Juniper Networks® E320 and E120 Broadband Services Routers. Introduced in 2005, the award-winning E320 BSR provides the high system capacity as well as the high subscriber and interface density required for large broadband deployments. The E120 BSR, introduced in 2007, provides the same comprehensive feature set as the E320 in a platform designed for smaller configurations. Both platforms uniquely combine advanced hardware and software that support service provider efforts to reduce operations costs and drive new revenue opportunities via advanced services that include bundled voice and Internet access, virtual private networks (VPNs), IPTV, gaming, and streaming music applications.
The E320 and E120 share a common system architecture that distributes packet processing and quality of service (QoS) policy enforcement functions to ASIC-based line modules. This design provides a fast path for IP traffic streams by removing the route processor from the forwarding path, and ensures performance at scale by incrementally adding processing power as new subscribers and services are provisioned.
The E320 and E120 also share a modular, carrier-class design with optional redundancy on all major hardware subsystems and common equipment—including switch fabric, route processing, and packet processing redundancy—as well as interface card and interface-level protection schemes. Furthermore, both platforms are powered by the Juniper Networks JUNOSe™ software. The modular, object-oriented, and component- based architecture of the production-hardened JUNOSe increases overall system reliability, simplifies upgrades, and accelerates new feature development.
Together with JUNOSe, the E320 and E120 incorporate the vast experience Juniper has gained over many years of supporting service providers worldwide, and provide a comprehensive solution for the profitable deployment of services to residential and business customers alike.
Architecture and Key Components
The E320 BSR is a high-performance routing platform optimized for large point of presence (POP) environments and multiplay service delivery. Service providers can optionally equip their E320 with either a 100 Gbps or a 320 Gbps switch fabric.
The E120 BSR, with its 120 Gbps switch fabric, is a high-performance routing platform optimized for smaller POPs and central offices and multiplay service delivery.
