Juniper Networks E-series Broadband Service Routing Platform
The E-series portfolio of IP edge and broadband services routing platforms is a critical element in the control, delivery and accounting of services at the network edge. The E-series includes six different models that are designed to efficiently address the widest variety of service provider requirements. The specific models include the high-capacity E320 BSR and E120 BSR platforms; the mid-range ERX-1440 and ERX-1410 platforms; and the compact ERX-710, ERX-705 and ERX-310. All E-series platforms utilize a single version of the proven JUNOSe operating system, which ensures both feature and operational consistency.
Powered by the mature and broadly deployed JUNOSe, the E-series portfolio helps service providers migrate from basic "best effort" IP services to exciting new, high value multiplay services that bundle a broad set of IP voice, video and data applications. JUNOSe, with its carrier-grade architecture, underpins the reliable and efficient delivery of advanced services to both business and residential broadband customers. In addition, JUNOSe is fully integrated with Juniper's Session and Resource Control portfolio for automated service creation and policy-driven control of network resources.
With an unsurpassed combination of powerful hardware packet processing and software flexibility, the E-series portfolio and JUNOSe provides the performance, scale and "always on" availability required at the network edge. Deployed in hundreds of production networks worldwide, the E-Series portfolio is relied on by service providers for its predictable high performance and service flexibility. These routers cost-effectively address subscriber management, edge routing and service aggregation requirements at carrier scale.

Cross-platform Feature Consistency via JUNOSe
The E-series platforms 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.
QoS policy enforcement is also distributed to the Line Modules, which examine, classify and queue packets at full wire speed. Because QoS handling is distributed, overall system performance and service quality are maintained under all network conditions.
Comprehensive Subscriber Management Features
Advanced QoS: JUNOSe incorporates application-aware intelligence to respond to real-time changes in the application mix, to ensure the quality delivery of voice and video services even as subscribers concurrently consume multiple services over the same physical connection. Furthermore, the E-Series platforms support fine-grained IP QoS capabilities at line rate for all subscriber flows, ensuring that QoS policies are enforced and that high priority traffic–whether low-latency Voice over IP, mission-critical business applications, or loss-sensitive video services–receives the appropriate level of preferential treatment to ensure subscriber satisfaction.
Capital Efficiency: Service providers can select the E-series platforms that best address their business and technical needs based on system capacity, subscriber density, redundancy options, cost and many other important criteria, without compromising on reliability or features.
Operational Efficiency: Consistent JUNOSe implementation across the entire E-Series portfolio ensures a common operations environment, which helps contain OpEx, speed new service creation and improve new service roll out. Broad capabilities, including zero-touch provisioning, subscriber management support for DHCP and PPP clients and extensive OAM&P features, further enhance the operational benefits.
Increased Service Revenue Opportunities: The sophisticated QoS capabilities of the E-series portfolio and the feature-rich JUNOSe operating system work together to deliver the widest range of high-value services to both business and residential customers with performance and reliability. With features that support throughput guarantees and preferred traffic treatment on a granular basis, the E-series portfolio helps service providers in their efforts to increase competitive differentiation and increase revenues.
