E SERIES
BROADBAND
SERVICES ROUTERS
Product Overview
Broadband edge networks must
provide reliable and scalable high
performance to meet stringent
service-level agreements and elevated
customer expectations associated
with Internet access, IPTV, video on
demand, voice over IP (VoIP) and
interactive applications. E Series
Broadband Services Routers flexibly
address these diverse and demanding
business and technical requirements
while helping to control operational
costs. Hundreds of service providers
worldwide continue to rely on the E
Series platforms as they migrate to the
cutting-edge MX Series 3D Universal
Edge Routers with Broadband Network
Gateway (BNG) capabilities.
Product Description
Service providers depend on Juniper Networks® E Series Broadband Services Routers to
support high-speed Internet access, IPTV, video on demand, voice over IP (VoIP), online
gaming, and a host of interactive applications. The E Series consists of broadbandoptimized platforms that offer the carrier-class reliability, availability, scale, and
performance needed for business and residential services alike.
All E Series platforms are designed with a multiprocessor hardware-assisted packet
forwarding architecture that efficiently provides incremental processing power as
subscriber density increases. This distributed design ensures that service quality is
maintained for both traditional services and emerging multiplay applications, even at
peak traffic loads and with multiple services concurrently enabled.
In addition to this high-performance architecture, the entire E Series family provides a
comprehensive set of subscriber management capabilities that are complemented with
the robust, world-class routing features that customers expect from Juniper, including
comprehensive implementations of MPLS, BGP4, IS-IS, OSPF, and RIP.
The E Series also provides advanced native IPv6 support for fast-path forwarding and
routing, packet classification, policy, hierarchical quality of service (QoS), subscriber
management, tunneling, and denial-of-service (DoS) attack prevention. Importantly, the
E Series concurrently supports a sophisticated IPv4 and IPv6 “dual stack” implementation,
permitting concurrent IPv4 and IPv6 operation.
In summary, many service providers worldwide rely on the E Series to meet their
broadband edge requirements as they evolve to the MX Series 3D Universal Edge Router
with BNG capabilities.
Architecture and Key Components
The E120 and E320 are advanced broadband services routing (BSR) platforms designed
for demanding multiplay applications and complex service bundles. Both platforms
support redundant route processing and switch fabric modules, and all common
components are hot-swappable without service interruption. The E120 and E320 share
many components, including line modules and interface modules (Input-Output Adapters
or IOAs), making sparing easier in mixed platform networks.
The E320 can be flexibly configured with either a 100 Gbps or a 320 Gbps switch fabric
and hosts up to 12 line modules, while the E120 has a 120 Gbps switch fabric and hosts
up to six line modules. Both the E320 and E120 support OC3/STM1, OC12-STM4, OC48c/
STM16, GbE, and 10GbE technologies, as well as both full-height and half-height IOAs that
permit flexible and efficient physical network connectivity.
