Juniper
E-Series is a series of Broadband
Services routers or edge routers manufactured by Juniper Networks
. The E series was originally developed by Unisphere Networks
, which Juniper acquired in 2002. These routers provide multiple services including broadband remote access server, broadband video services, dedicated access, 802.11 wireless
subscriber management, VOIP, internet access, security services, network address translation (NAT
) etc. on a single platform.The carrier-class architecture of E-series routers allows to combine Broadband Remote Access Server (B-RAS) and dedicated access capabilities (T1/E1 and above) on a single and integrated platform. The E-series routes runs on JUNOS

(QOS) and high availability that carriers want for IPTV, as well as a huge increase in density. Cisco Systems
has two boxes selling into this space: the 10000 series, considered Cisco's primary B-RAS entry, and the 7600
line of edge routers (of which the 7613 is the largest), which include some B-RAS capabilities. The B-RAS Backplane Switching Capacities of E320 supports up to 320 Gbit/s compared to 256 Gbit/s of Cisco 7613.
The E-series JUNOSe system software and applications supports stateful Switch Route Processor switchover capabilities. The high availability for subscriber management applications, including all Point-to-Point Protocol and Dynamic Host Configuration Protocol
access options, means that all subscriber sessions and services remain active during failure.
These routers maintain an entire routing table
per port, which removes the route processor from the forwarding path and provides wire speed performance IP traffic streams, a process aided by Juniper developed ASIC technology.
The E-series supports subscriber management features in order to effectively aggregate traffic from access multiplexers, terminate Point-to-Point Protocol
(PPP) sessions, and enforce QoS policies on a per flow and per subscriber basis. Features includes support for DHCP, PPPoE, PPPoA, PAP
, and CHAP
