E-Series Routers

Five models of E-series routers are available:

•ERX-1440 router

•ERX-1410 router

•ERX-710 router

•ERX-705 router

•ERX-310 router

All models use the same software. For information about the differences between the models, see Chapter 1, E-Series Overview.

In the E-series documentation, the term ERX-14xx models refers to both the ERX-1440 router and the ERX-1410 router. Similarly, the term ERX-7xx models refers to both the ERX-710 router and the ERX-705 router. The terms ERX-1440 router, ERX-1410 router, ERX-710 router, ERX-705 router, and ERX-310 router refer to the speciﬁc models.

ERX-710, ERX-310 specifications

Juniper Networks has long been a significant name in the networking sphere, and the ERX series, particularly the ERX-310 and ERX-710, highlights the company's commitment to providing robust, high-performance edge routing solutions. These routers are designed for service providers needing to support a wide array of services, including broadband, voice, and video over IP.

The Juniper ERX-310 is a compact and versatile access router suitable for small to medium-sized service providers. It features scalable architecture that can grow with the operator's needs. With its support for integrated T1/E1 interfaces, the ERX-310 allows seamless deployment of broadband services while providing QoS mechanisms to prioritize traffic effectively. Its modular design includes slots for additional interfaces, ensuring flexibility in deployment scenarios. The device is capable of processing millions of packets per second, thanks to its advanced forwarding architecture.

On the other hand, the ERX-710 is a more powerful option, targeting larger enterprises and service providers. This router also comes with modular capabilities, supporting various interface options and enabling efficient traffic management across multiple services. The ERX-710 supports advanced routing protocols, including BGP, OSPF, and IS-IS, ensuring reliable and efficient routing of IP packets across complex networks. With its ability to support a higher capacity of subscribers and concurrent sessions, the ERX-710 is designed to meet the increasing demands of modern broadband services.

Both routers come with robust security features, including access control lists (ACLs), firewalls, and the option for IPsec VPNs, ensuring that data integrity and confidentiality are maintained. Multicast support is another critical feature that enhances the ERX series' ability to deliver rich content services efficiently.

Furthermore, both models utilize Juniper's Chassis-based architecture, which allows operators to start small and scale up as needed without complete equipment overhauls. This architecture is complemented by Juniper's JUNOS operating system, renowned for its reliability and powerful network management capabilities, providing users with enhanced visibility into network operations.

In summary, Juniper Networks' ERX-310 and ERX-710 routers exemplify the company's innovation in network router technology, catering to different operational scales while ensuring efficiency, flexibility, and robust performance across diverse service environments. Their rich feature sets and adherence to industry standards make them suitable choices for service providers striving to deliver high-quality service in an increasingly data-driven world.
