Juniper Networks J Series Routers

The J-series Services Router delivers the advanced JUNOS modular operating system in a hardware platform that is ideal for smaller sites, including remote, branch, and regional offices.

The JUNOS software runs many functions independently, to deliver high levels of security, uptime, and performance, with reduced operations effort. The J-series routers provide enterprises, government organizations, and research and education groups with a forward-looking platform to build converged IP and IP/MPLS infrastructures.

The modular and coherent design of the JUNOS operating system is fundamentally different from legacy routing systems. By running multiple functions in parallel on assigned processing resources, JUNOS software delivers high stability with the flexibility to enable advanced routing, QoS, security, and management policies with predictable performance. The J-Series line includes the J2300, J4300, and J6300 Services Routers.

Features

Key features and benefits of the J-series routers include the following:

• Comprehensive range of interfaces supporting Serial, T1/E1, FE, DS3/E3, ISDN, ADSL /2/2 and G.SHDSL
• A full, rich set of IPv4/IPv6 features and routing protocols combined with the richest set of MPLS features available
• Wide array of Layer 2 access protocols including Frame Relay, Ethernet, and PPP/HDLC
• Rich and granular QoS and instrumentation for prioritizing mission-critical traffic such as voice
• Network Address Translation (NAT), Stateful firewall, IPSec, and J-Flow accounting
• Single JUNOS image, regardless of features activated, for reduced operational cost and complexity

Benefits

With the JUNOS operating system, the Juniper Networks J-series routers deliver the following benefits to the enterprise:

• Security - Juniper Networks delivers the most advanced set of mechanisms for fully protecting routers from outside threats. The J-series routers give network staff complete control, even while under attack, with the console port always available to add new filters and policies with just a few fast and simple steps.
• High uptime - The modular and fault-protected software design of the JUNOS operating system delivers high levels of resiliency and stability in the J-series routers. Unlike traditional routers, which any small bug can quickly spread into a larger problem, each software module in the JUNOS operating system runs independently and cannot impact other areas. Other resiliency features include next-generation CLI for accurate configuration, and a rescue button for fast system recovery.
• Predictable performance - The J-series routers maintain high levels of QoS control and throughput when needed for the most demanding periods of network congestion. Modular software architectures are essential for the sorting and scheduling of traffic to ensure that the most important applications have first priority with networking resources.
• Reduced operation - JUNOS software, JUNOS CLI, and Juniper Networks management platforms reduce the operation complexities that occur in networks to ease remote support and management. Advances in remote operations include a rescue button that any on-site personnel can activate; commit check, commit confirm, and configuration rollback to ensure the validity of configuration changes; and auto-record features that support rapid diagnostics. Additionally, JUNOS software has one code train, and the operating system is standard across the routing product line, to greatly reduce the effort required for software patches and upgrades.
