Session Smart Networking Datasheet
Download DatasheetProduct Overview
The Juniper Session Smart Router (SSR) powers Juniper’s AI-driven SD-WAN solution that is designed to provide users with exceptional experiences. Built on an application-aware and zero-trust secure network fabric, the SSR meets the most stringent enterprise performance, security, and availability requirements.
The SSR overcomes inherent inefficiencies of conventional solutions with a tunnel-free architecture that enables improved performance, fast deployments, and cost savings. The solution can run on customer premises equipment (CPE), data center network servers, and in the cloud for flexible deployments.
Product Description
Juniper Networks® SSR Series Routers power Juniper’s AI-driven SD-WAN solution. The software-based solution utilizes a unique, tunnel-free routing protocol called Secure Vector Routing. This innovative networking solution improves application performance, rapidly scales to thousands of sites, and secures users and data with inherent, zero trust access policies.
The Session Smart™ Router can be managed by either the Juniper Session Smart Conductor or the Juniper Mist™ Cloud. Together, these platforms create a single logical control plane that is highly distributed, and a data plane that is truly session aware. SSR supports a wide range of use cases, including SD-WAN, SD-Branch, Multi-cloud and IoT and can scale from a small branch office to a high-capacity edge router to a hyper-scale, software-defined data center (Figure 1).

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.
The Session Smart Router also provides native zero-trust security, leveraging hypersegmentation. It also 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.
- Firewall capabilities: The Session Smart Router provides Layer 3/ Layer 4 network firewall functionality.
- IDS/IPS and URL filtering: Intrusion Detection System/Intrusion Prevention System (IDS/IPS) and URL filtering capabilities are available through the Advanced Security Pack.
- 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. The 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 the Juniper Mist 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.
