Juniper Networks continues to integrate and expand its portfolio of cloud-based, AI-driven services that are aimed at helping customers manage and control enterprise networks. 

At the core of those services is technology Juniper gained in its acquisition of wireless and AI software maker Mist in 2019 for $405 million. Mist's technology includes an AI-based engine called Marvis that uses machine learning to automatically identify, adapt to, and fix network issues. 

The natural language-based Marvis engine is at the core of multiple Juniper services, including its Wi-Fi Assurance offering, which measures performance and service-level metrics for wireless networks; Wired Assurance, which taps into Juniper's network routers and switches to gather telemetry data that measures network performance; and WAN Assurance, a cloud-based service that will gather telemetry data from Juniper SRX, Contrail and other WAN gear and pass that information to Marvis.

Marvis can understand what's normal activity on the network, look for anomalies, and offer suggestions to fix problems and ensure WAN service levels. In many cases, Marvis can respond without human intervention, Juniper says.

On top of those existing services, Juniper has now brought in the SD-WAN technology it acquired from 128 Technology in December for $450 million. 128's key technology is its Session Smart software that promises to reduce the costs of running SD-WAN and WANs by making intelligent routing decisions based on sessions and application needs over individual traditional tunnels.
