Junos Evolves for the Cloud Era
Jul 30, 2019

Juniper Networks has a distinguished record as a disruptor and a change leader in the networking industry. 

 

Juniper technologies helped fuel the rapid growth of the internet in the early 2000s by decoupling the data-plane of an IP router from its control plane and creating routers that moved IP traffic many times faster and more economically than before. Junos OS, the software brain of Juniper routers, switches and security appliances, integrated market-leading innovation into an open-source Unix OS, namely FreeBSD. Among other things, Junos introduced innovative ways of managing network devices, leading to standardized modeling languages and protocols, such as YANG and NETCONF, laying the foundation for programmability and automation that the industry has broadly adopted today. More recent innovations include virtualization, node slicing and the ability to support 3rd-party white box hardware, to name a few. Furthermore, Juniper consistently maintains a strong presence in standards bodies evangelizing open programmability to ensure freedom of choice for the entire networking industry.

 

Junos-Evolved-Blog.pngThe networking industry is in transition again with cloud, 5G and SDN creating new challenges, as well as opportunities. These, in turn, require new network architecture approaches. Juniper’s engineering team has been busy designing software infrastructure to enable new paradigms such as scale-out architectures, disaggregated and cloud-native functions, lean and open-source compliant OS stacks, as well as the ability to offer much greater availability, programmability, visibility, feature development and deployment agility for operational efficiencies in traditional deployment models. This effort has produced a new generation of infrastructure evolution within Junos, sometimes referred to as “Junos OS Evolved,” that imbues powerful capabilities to the overall Junos operating system while maintaining One Junos experience. 

 

New Capabilities

The latest Junos release incorporates the following capabilities:

  • Linux OS and Linux native application components enable the user to leverage the integrated tooling and operational mechanisms of the rich Linux open-source community
  • Logically centralized state database and a publish/subscribe state distribution system for advanced observability, troubleshooting and remediation
  • Model representation of the entire config and state, enabling machine-driven automation
  • Full software modularity with strong fault isolation boundaries for higher availability
  • Containerized OS components with patching and upgrade capability for availability and run-time upgrades of on-device software, as well as the ability to run software decoupled from hardware in cloud-native environments
  • Native support for 3rd-party software agents enabling easy customization
  • Next generation data-plane software sub-system with a programmable and open API
  • Powerful and intrinsic distributed system facility for enabling new paradigms such as distributed chassis and cloud-hosted control planes

As software evolves, especially when it is deployed on hundreds of thousands of devices around the globe, an ecosystem of operational experiences, best practices, management tools and trust also evolves around it. At Juniper, we realize the importance of preserving the One Junos experience by keeping the following aspects consistent across our releases:

  • System and application data models and interfaces via SNMP, CLI, NETCONF, Streaming Telemetry, etc.
  • Programmability via our Juniper Extension Toolkit (JET) Control Plane APIs
  • Forwarding plane API via Openflow, P4, Advanced Forwarding Toolkit (AFT)
  • Key control and management plane applications

 

Junos OS Evolved brings powerful and innovative new infrastructure capabilities. It enables the next generation of network architecture deployments with the goal of meeting and exceeding the needs and expectations of our customers well into the future.
