Figure 1: Disaggregated Junos OS software

• Open Data Models: Since its inception, Junos OS has been

modeling the configuration and operational state internally

using what was effectively the precursor of YANG.What Junos

OS pioneered has effectively become the industry standard,

where Network Configuration Protocol (NETCONF) is used as

a transport mechanism, while YANG is used as a data-modeling

language. In addition to supporting YANG to model

configuration objects, Junos OS also supports the standardized

YANG models and OpenConfig.

• Junos Continuity: A major cause of downtime is the need to

upgrade the network OS whenever new hardware, such as a

line card, is installed in a device. These upgrades and the

subsequent reboot always impact existing services. Junos

Continuity provides a plug-and-play approach that ensures

high network availability, preventing required device reboots

by making the insertion of new line cards a non-service

impacting event.

• Junos Node Slicing: Junos Node Slicing supports the

convergence of multiple concurrent network functions on the

same physical infrastructure. This gives service providers the

ability to optimize their infrastructure, while offering

differentiated services with enhanced operational and

administrative isolation with a single chassis. By decoupling the

network software from underlying infrastructure, Junos Node

Slicing accelerates service deployment, reduces capital outlay,

and improves operational efficiency.

Features and Benefits

Revenue Growth

The programmability and automation capabilities of Junos OS give

service providers and enterprises the ability to automate business-

critical services. This frees up valuable resources for innovation and

optimal user experiences, which ultimately leads to greater

customer satisfaction and brand loyalty. Junos Node Slicing

optimizes the network infrastructure, enabling the convergence of

multiple concurrent network functions on a single chassis,

dramatically improving operational efficiency and top-line growth

opportunities.

Cost Efficiencies

Junos OS improves the overall cost efficiency of network

deployments. Junos Node Slicing enables the convergence of

multiple concurrent network functions with a single chassis,

maximizing the utilization of network nodes and improving CapEx

efficiency. OpEx efficiency is achieved through automation, which

replaces the extensive manual processes required by traditional

network configuration, management, and operation, drastically

simplifying network operations and virtually eliminating human

errors.

Agility

Business requirements are always evolving, reflecting constantly

changing market dynamics. The programmability and open-source

automation frameworks supported by Junos OS give service

providers and enterprises the ability to rapidly implement

customized network services and deploy business-critical

applications.
