Junos OS Product Description

The Junos OS from Juniper Networks includes IP routing protocol software, as well as software for management of interfaces, networks, and chassis. The Junos OS runs on the following Juniper Networks devices:

• EX Series Ethernet Switches
• J Series Services Routers
• M Series Multiservice Edge Routers
• MX Series Ethernet Services Routers
• SRX Series Services Gateways
• T Series Core Routers

Juniper Networks routers use two types of processing engine:

• Routing Engine—Maintains routing tables and controls routing protocols.
• Packet Forwarding Engine—Forwards network traffic, which is processed by application-specific integrated circuits (ASICs) and other components.

Juniper Networks offers three versions of the Junos OS:

• Canada and United States version, which incorporates cryptographic functionality and is therefore subject to export controls. When used in combination with an ES PIC, the strong cryptographic functionality in the Canada and U.S. version of the Junos OS substantially supports IP Security (IPsec). The software also supports secure remote network management sessions (using SSH and Secure Sockets Layer [SSL]), and secure transmission of control traffic between Routing Engines (using SSH).
• Worldwide version, which omits most cryptographic functionality, including support for IPsec with the ES PIC.
• Junos-FIPS version, which meets the requirements of Federal Information Processing Standard (FIPS) PUB 140-2.
