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.
address the diverse requirements of
The E320 and E120 share a sophisticated system architecture that distributes packet
the broadband network edge with
processing and quality of service (QoS) policy enforcement functions to ASIC-based line
unprecedented capacity, reliability and
modules. This high performance design provides a ‘fast path’ for all traffic streams by
performance.
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.
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 JunosE OS to support many tens of
millions of broadband subscribers every day.
