Product Description
Product Overview
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.
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.
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.

flexible high capacity
The E320 BSR supports a 100 Gbps or a 320 Gbps
switch fabric (40 M-180 Mpps performance).
Reduces operating and capital expenses:
aggregates more subscribers and services.
Environmental efficiency
The E120 BSR has a small form factor and reduced Extends market reach: the E120 extends high
power budget for operation in smaller POPs/central BSR performance to smaller POPs/COs without
offices.

line rate forwarding using
Juniper’s custom aSics
Hardware-based forwarding, with separate
processors for routing and forwarding tasks.
Improves performance: ensures high performance
for multiplay services, at carrier scale.
Sophisticated QoS feature set
Features include hierarchical queuing and
scheduling, rate-limiting for individual queues and
logical/physical interfaces.
Assures quality of experience: supports quality
multiplay services to both residential and business
consumers.
High availability
All major hardware subsystems and common
equipment can be redundantly configured, while
JUNOSe is a carrier-grade OS.
Improves customer satisfaction: the combination of
dependable hardware and reliable software delivers
“always-on” services.
