DATASHEET

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.

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.
