End-to-End Assurance with an AI-Native Campus and Branch Solution Brief

Today’s enterprise networks must support multiple data centers and a myriad of campus, branch, and edge locations with an array of hybrid, private, and public cloud solutions. Network reliability, security, and scalability have become strategically critical. Yet complexity contributes to significant management challenges, and network complexity only continues to grow. Just consider that 73% of respondents to an Enterprise Strategy Group survey said their network had grown more complex over the past two years.

AI-Native Campus and Branch Solutions transform distributed networking in support of exceptional experiences for users and IT alike.

By leveraging the cloud and AIOps, AI-Native Campus and Branch Solutions provide state-of-the-art automation, with continuous insights and recommended actions across all network domains (Figure 1).

The capabilities not only support in-house implementations, they can also deliver significant value to Managed Service Provider (MSP) implementations. AI-Native capabilities identify problems that operators—whether in-house or third-party—may not even know exist, leading to faster issue identification and resolution—and lower costs. And they are available as a fully-managed service, an in-house approach, or a hybrid approach.

Juniper is the only vendor with a fully integrated AI-Native Networking Platform and portfolio of AI-Native Campus and Branch solutions. The unique combination of wireless access, wired access, SD-WAN, indoor location services, NAC, and firewalling under a common Mist AI engine and microservices cloud infrastructure underpins rapid deployments and streamlined management. The integrated approach not only helps significantly reduce TCO and OPEX, it enables measurable end-to-end assurance. (Figure 2).

AI-Native Campus and Branch solutions measure user experience by reporting on characteristics such as application response time to and from the cloud. When users and devices connect to a wireless network, the Juniper Mist Cloud correlates events in the wireless, wired, and WAN domains to ensure Service Level Expectation (SLE) are being met. This comprehensive approach provides assurance that all individuals and devices accessing the network have exceptional experiences.

Historically, network troubleshooting and optimization has been a reactive exercise. With Juniper, however, operators can proactively identify and address issues before users even know they exist. It’s all thanks to the cloud-based Mist AI engine, which uses a combination of artificial intelligence, machine learning, and data science techniques to optimize user experiences and simplify operations.

To deliver the best agility and scale—and fastest deployment times—Juniper relies on a microservices cloud underpinned by a 100% open API architecture. Microservices make it possible to rapidly process and analyze the rich telemetry data essential to AI-driven automation, as well as support seamless feature rollouts with zero downtime. The cloud continually feeds user, device, network element, and application states to Mist.

To understand what AI-Native Campus and Branch solutions can do, consider a user’s dropped video call that that could be related to events in multiple domains. (Figure 3). Possible culprits include:

• Difficulty connecting to the Wi-Fi Access Point
• A bad Ethernet cable on the router further upstream
• Low performance on a virtual machine from the video application server that is housed in a cloud data center
• A problem with the user’s PC, or internet connection, or a node in the enterprise WAN

With end-to-end event correlation, anomaly detection, and self-driving capabilities tied to service levels, administrators can easily isolate the domain and the failing component. In many cases, a virtual network assistant can either direct the administrator to the problem or perform the repair itself, saving the IT team significant time.

Juniper further assures video experiences by incorporating Zoom experience information into Marvis, the first AI-Native virtual network assistant, and providing insights into performance and potential issues via a natural language user interface.

For a real-world example of optimized user experience and cross-domain problem resolution, see the Dartmouth case study.

The Juniper Mist AI platform enables predictable, reliable, and measurable networking with industry-leading AIOps—that rely on more than nine years of reinforced learnings—and unprecedented visibility into user and device experiences. It starts with analyzing large amounts of rich metadata collected from Juniper high-performance Access Points, Juniper EX Series Switches, and Juniper Session Smart Routers and SRX branch firewalls to provide actionable insights from across wireless, wired, and WAN domains.

To assure the best user experiences, the Juniper Mist AI Cloud offers customizable service levels for clients, applications, and networks, and makes proactive recommendations that enable IT teams to move quickly and decisively on any issues that arise.

Here’s a high-level look at key attributes, features, and components of the AI-Native Campus and Branch Solutions portfolio.

The Juniper Mist microservices architecture is built on a distributed set of independently deployable and manageable modules that run various application services. The approach allows for the elastic scaling of services up or down as needed across the extended enterprise and eliminates the need for costly and complex monolithic hardware. It seamlessly delivers enhancements and bug fixes without the need for downtime or impact on users. And the platform is inherently resilient: A failure in one service does not impact others.

The Marvis Virtual Network Assistant (VNA) is a groundbreaking support tool with a conversational AI interface (with ChatGPT support). Users can rely on Marvis to understand and quickly remediate issues impacting devices and users anywhere in the network. Marvis Minis, the industry’s first AI-Native Digital Experience Twin, works with Mist AI to proactively simulate user activity to instantly validate network configurations and detect problems before they happen. Marvis can also identify and resolve the root cause of many network issues across WLAN, LAN, WAN, and security domains through proactive actions.

In the wireless domain, Mist Wireless (Wi-Fi) Assurance uses machine learning to make Wi-Fi predictable, reliable, and measurable and ensure optimal user experiences. It starts with collecting data through Juniper Access Points. Mist AI then employs machine learning to correlate events with root causes and solutions and provide in-depth service-level visibility and actionable insights.

Juniper Mist Premium Analytics is a cloud-based subscription service that provides end-to-end network observability and business intelligence to IT networking and line-of-business users. It offers long-term data storage for full-stack network and location insights. Easy-to-use dashboards give networking teams client-to-cloud visibility, enabling them to quickly identify and address issues, plan their IT infrastructure, and manage resources.

Juniper’s Mist Access Assurance combines full network access control (NAC) and policy enforcement to simplify network operations. For IoT and BYOD, Juniper Mist IoT Assurance provides a full suite of access control functionality using multiple and private pre-shared keys (MPSK and PPSK).

For more information, see the Wi-Fi Assurance page and the Wi-Fi Assurance Overview.

Juniper Mist Wired Assurance is a cloud service that brings automated operations to campus fabrics, delivering unparalleled user and IT experiences for campus switching through simpler operations, shorter mean time to repair (MTTR), and better visibility into connected devices.

Juniper EX and Juniper QFX Series Ethernet Switches provide rich telemetry through the Junos^® operating system, which enables insights into what the switch is experiencing and how it is doing. In addition to providing metrics about switch health and performance of connected devices (Figure 6), Wired Assurance:

• Enables single-click activation and auto provisioning of EX switches
• Brings cloud management and Mist AI to the campus fabric
• Supports wired service-level expectations (SLES) and third-party integrations

For more information, see the Wired Assurance page and the Wired Assurance data sheet.

Juniper Mist WAN Assurance is a cloud service that can add AI-Native automation and insights, along with SLEs, to Juniper AI-Driven SD-WAN deployments.

Powered by Mist AI and the Marvis Virtual Network Assistant, WAN Assurance supports zero-touch provisioning (ZTP) for plug-and-play installation at remote sites with minimal or no IT expertise required. It also provides AIOps capabilities to help understand and optimize user experiences across the SD-WAN (Figure 7).

The analytics in WAN Assurance are provided by the tunnel-free SD-WAN, which offers a flexible, application-aware network fabric that meets stringent enterprise performance, security, and availability requirements.

Juniper SD-WAN relies on Session Smart Routers to securely connect all branch offices to data centers, local clouds, public clouds, or cloud services (Figure 8).

Juniper SD-WAN not only uses a deny-by-default approach to session access to enable Zero Trust security, it also uses a host of security features to provide industry-leading protections (Figure 9).

The Session Smart Routers in Juniper SD-WAN provide a tunnel-free, low overhead architecture that collects session and application data. Based on customer results, the combined features and capabilities in Juniper SD-WAN can reduce bandwidth consumption by up to 50% compared to alternative networking platforms.

The largest scale deployment of SSR routers is 10,000+ sites in an SD-WAN installation.
