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 JunosE ? 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. JunosE OS also supports an extensive set of high availability features, such as Unified In Service Software Upgrade and Stateful Control Plane (SRP) switchover. T ogether 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 JunosE OS to support many tens of millions of broadband subscribers every day.
Product Overview
Service Providers face many challenges as they offer increasingly complex multiplay service bundles over their broadband networks. Juniper Networks E320 and E120 Broadband Services Routers provide advanced subscriber management, high-performance routing, efficient Ethernet aggregation, and superior quality of service that address the diverse requirements of the broadband network edge with unprecedented capacity, reliability and performance.
E320 AND E120 BROADBAND
SERVICES ROUTERS
Architecture and Key Components
The E320 is a high-performance routing platform optimized
for multiplay service delivery in large point of presence (POP) environments. Service providers can optionally equip the E320 with either a 100 Gbps or a 320 Gbps switch fabric, based on their specific bandwidth requirements.
The E120, with its 120 Gbps switch fabric, is a high-performance routing platform optimized for multiplay service delivery in smaller POPs and even central offices.
The E320 and the E120 share many common components, and both support:
? Switch route processors (SRPs) that perform system management, routing table calculations maintenance,
forwarding table computations, and other control plane
functions.? Switch fabric modules (SFMs) that create a distributed shared memory switching fabric.
? Line modules (LMs) that provide frame processing and forwarding for IOA modules.
? Power modules that distribute redundant power feeds to all components installed in the router through the system to all components.
? I/O Adapter (IOA) modules that flexibly provide the physical network connection via 10-Gigabit Ethernet, Gigabit Ethernet, Asynchronous Transfer Mode (ATM), and Packet over SONET (POS) interfaces.
The use of common components across both systems improves the operational environment by providing complete feature consistency and enabling a common sparing and management schema that helps lower total cost of ownership (TCO). The placement of these system components are as shown.
