Juniper Networks


Juniper Networks is a multinational publicly-listed IT company headquartered in California, with offices in nearly 50 countries. It specialises in Internet Protocol (IP) network products and services. Juniper Networks is a leader in high-performance networking, and its products are widely used in large networks around the world.

The company was founded in 1996 by Pradeep Sindhu, and was built around the concept of creating reliable, high-performance routers to support the quickly-emerging Internet. By 2000 Juniper took 30 percent of the core router market.

Core Competencies

Juniper Networks' core competencies lie in architecture, silicon design, and its JUNOS network operating system. Its product portfolio spans routing, switching, security, application acceleration, identity policy and control, and management.


Juniper's products include the T-series, M-series, E-series, MX-series, and J-series families of routers; EX-series Ethernet switches; WX-series WAN optimisation devices; and SRC Session and Resource Control appliances.

Juniper's network operating system JUNOS is marketed by Juniper as the industry's only carrier-class, purpose-built "pure IP" modular network operating system, and runs on most Juniper products. JUNOS is a single network operating system spanning routing, switching and security platforms.
