Product Description
Juniper Networks E Series Broadband Services Routers include the Juniper Networks E320 Broadband Services Router and E120 Broadband Services Router. The E320 provides the high system capacity, high subscriber density and high interface density that is ideal for large broadband edge service aggregation sites. The E120 provides the same comprehensive feature set as the E320 in a form factor that is designed for locations with lower service aggregation requirements. Both the E320 and the E120 share advanced hardware and Juniper Networks JunosETM operating system that helps service providers reduce operational costs and develop new revenue opportunities via advanced broadband services such as bundled multiplay offerings, voice and high-speed Internet access, IPTV and video conferencing, gaming, and many other multimedia applications.
The E320 and E120 share a sophisticated system architecture that distributes packet processing and quality of service (QoS) policy enforcement functions to ASIC-based line modules. This high performance design provides a ‘fast path’ for all traffic streams by removing route processing functions from the forwarding path, and ensures cost effective performance at scale by enabling the incremental addition of processing power to the system 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-this includes power and cooling. switch fabric, route processing, and packet processing redundancy-as well as a variety of interface card and interface-level protection schemes. Furthermore, both platforms are powered by JunosE OS, a modular, object-oriented, and component-based operating system that increases system reliability, simplifies operations, and accelerates new feature development. Junos OS also supports an extensive set of high availability features, such as Unified In Service Software Upgrade and Stateful Control Plane (SRP) switchover. Together with JunosE OS, the E320 and E120 incorporate the vast operational experience Juniper has gained over many years of supporting cutting edge broadband service deployments for both residential and business services; in fact, more than 200 service providers worldwide depend on the E Series and Junos OS to support many tens of millions of broadband subscribers every day.
