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.
