Product Overview

Juniper Session Smart Routing, which powers the AI-Driven SD-WAN, takes distributed, software-defined routing to a new level. This innovative networking solution provides a service-centric control plane and service-aware data plane that offers IP routing, feature-rich policy management, improved visibility, and proactive analytics. This next-generation SD-WAN solution supports the evolving needs of cloud-enabled enterprise networks.


Product Description

Juniper® Session Smart Routing fuels an advanced, service-centric networking solution that is rewriting the rules for software-defined routing and SD-WAN. Ideal for today’s digital businesses, the solution enables agile, secure, and resilient WAN connectivity with breakthrough economics and simplicity.

The unique combination of Juniper Session Smart Router, Juniper Session Smart Conductor, and Juniper Mist™ WAN Assurance cloud service transcends inherent inefficiencies and cost constraints of conventional networking products and legacy SD-WAN solutions. The Session Smart Router delivers a flexible, application-aware network fabric that meets stringent enterprise performance, security, and availability requirements. The Session Smart Router is software-based and deployable on white-box CPE, data center network servers, and the cloud. It’s also available with the purpose-built Juniper SSR Series Smart Router. It can be fully managed and orchestrated with Juniper’s Session Smart Conductor or through the Juniper Mist WAN Assurance cloud service.

Product Components

The Session Smart Router is a base component that can be paired with either the Juniper Session Smart Conductor or the Juniper Mist cloud. Together, they form a single logical control plane that is highly distributed and a data plane that is truly session aware. They support a range of use cases, including SD-WAN, which can scale from a small branch office to a high-capacity edge router to a hyper-scale, software-defined data center. 

Session Smart Router

The Session Smart Router combines a service-centric control plane and a session-aware data plane to offer IP routing, feature-rich policy management, improved visibility, and proactive analytics. Session Smart Router also provides native zero trust security, leveraging hyper-segmentation. It includes several security features.

  • Service-centric, tenant-based security architecture: The unique design enables the Session Smart Router to understand sessions and perform vital business operations. 
  • Zero trust security: The Session Smart Router follows the principle of “deny-by-default,” which uses a series of checkpoints to validate legitimate network traffic. 
  • Next-generation firewall capabilities: The Session Smart Router provides network firewall functionality and can be service-function chained with Juniper Networks® SRX Series Services Gateways for next-generation firewall capabilities. Additionally, the following capabilities are available as add-on options for the SSR Series routers: 
    • Intrusion Detection System/Intrusion Prevention System (IDS/IDP)
    • URL filter
  • Security at its core: The advanced design of the Session Smart Router replaces the traditional routing plane with one built for security from the ground up.

Session Smart Conductor

The Session Smart Conductor is a centralized management and policy engine that provides orchestration, administration, zero-touch provisioning (ZTP), monitoring, and analytics for distributed Session Smart Routers—while maintaining a network-wide, multi-tenant service, and policy data model. Session Smart Conductor features multiple, flexible deployment models, from on-premises to private or public cloud.

Juniper Mist™ WAN Assurance and AI-Driven Operations

Alternatively, Session Smart Routers can be operated and orchestrated through the Juniper Mist cloud. Mist AI delivers unprecedented automation using a combination of artificial intelligence, machine learning algorithms, and data sciences techniques to save time, maximize IT productivity, and deliver the best experience to digital users. 

Juniper Mist WAN Assurance is built on the Mist AI cloud and delivers full life cycle management and operations, including AI-driven insights, anomaly detection, and root cause identification that focuses on end users’ experience. For day-0 and day-1 operations, WAN Assurance also provides orchestration, administration, and ZTP for Session Smart Routers. See the WAN Assurance datasheet for more information.
