Overview

JUNOS™ software is the trusted network operating system driving Juniper Networks leadership in high-performance networking. Juniper aggressively drives JUNOS software innovation through its disciplined development as a single-source network operating system that integrates routing, switching, security and other services. Our extensive portfolio connects enterprise branch and regional offices, central sites and data centers, along with the metro, edge and core sites of service provider networks.

What sets JUNOS software apart from other network operating systems is the way it is built—one operating system enhanced through one release and developed from one modular architecture. Service providers, businesses, and public sector organizations that deploy JUNOS software benefit from its three key advantages:

• Continuous Systems: Improve network availability and the delivery of applications and services through high-performance software design, high availability features, prevention of human errors, and proactive operations measures.
• Automated Operations: Drive efficiency to lower operational expenses by reducing complexity with consistent feature implementation, error-resilient configuration, automated scripts for operations tasks, and the upgrade ease of one software release train.
• Accelerated Innovation: Enhance flexibility to deliver new services and applications through the open, standards-based philosophy and graceful extensibility of JUNOS software, including tools that open development to partners and customers.

What sets JUNOS software apart from other network operating systems is the way it is built—one operating system enhanced through one release and developed from one modular architecture.

Features and Benefits

JUNOS software helps customers in specific, measurable ways to improve network availability and the delivery of applications and services, to reduce operations effort and errors, and to meet new business needs.

JUNOS Software Advantage	JUNOS Software Attributes
Continuous Systems Improve network availability and the performance and security of services	Fault-tolerant modularity - enhances software stability and uptime with independent operation and restart of modules. Dedicated resources for control and packet forwarding - provide predictable performance as new services are activated and with a command-line interface (CLI) that doesn't lock-up. High availability features - preserve forwarding and control operations during device events with non-stop forwarding, Graceful Routing Engine Switchover (GRES), non-stop active routing, chassis clustering, etc. Single release train - enables the development control and extensive regression testing that underlie the software stability. Secure Operating System - protects with secure administration and advanced security features, including Stateful firewall, VPNs, etc. that deliver high throughput with many activated policies. Automated operations (see row below) - prevent human errors and provide proactive measures to reduce the total number, severity and duration of events.
Automated Operations Reduce operations effort and errors	Single implementation of features - provides a common user experience for control plane features to simplify deployment and training. Error-resilient configuration - prevents incomplete or incorrect configurations from becoming active in the network. On-box, custom commit scripts - check that configurations are error-free and comply with organizational policies. On-box, custom operation scripts and event policies - automate finding and proactively resolving issues from the first, leading indicators. Single release train - removes significant risk and effort from network upgrades.
Accelerate Innovation Meet new business needs with customized, best-in-class solutions	Partner Solution Development Platform - enables customers and partners to build applications on JUNOS software. Session Resource and Control portfolio and Open IP Service Creation Program - extend policy and control to applications and other systems. NETCONF/XML interfaces - support flexible integration to management and operations systems. JUNOScope IP Service Manager413 KB and J-Web86 KB provide central and web-based management of JUNOS-based platforms. Systematic development process - predictably provides many new features each quarter.
