Juniper Networks is looking to simplify the control of enterprise networks by expanding the AI-driven conversational interface of its cloud-based Mist management system and adding a new security access control service.\nJuniper is integrating the ChatGPT AI-based large language model (LLM) with Mist\u2019s virtual network assistant, Marvis. Marvis can detect and describe myriad network problems, including persistently failing wired or wireless clients, bad cables, access-point coverage holes, problematic WAN links, and insufficient radio-frequency capacity.\u00a0\nBy adding ChatGPT capabilities, Juniper is expanding the role of Marvis and augmenting its documentation and support options to help IT administrators quickly get the necessary assistance with problems or challenges, said Jeff Aaron, vice president of enterprise marketing at Juniper.\n\u201cAs part of Marvis\u2019s core functionality, we have always offered a natural language-based conversational interface (CI), whereby you can get\u00a0real-time\u00a0answers from Marvis to a variety of questions, like \u2018list any unhappy users right now\u2019 or \u2018troubleshoot Bob\u2019s team call,\u2019\u201d Aaron said. \u201cChatGPT augments the CI capabilities within our Marvis VNA by making it easier to query\u00a0documentation and historical knowledge-base data.\u00a0Questions like \u2018how do I configure a virtual chassis for my [Juniper] EX4400s?\u2019 or \u2018What do the LED patterns mean on my AP45?\u2019 are sample queries that benefit from this LLM integration,\u201d Aaron said.\n\u201cWith ChatGPT integration, we are able to understand the nature of the request and provide natural language replies, with easy pointers to where to go for additional information,\u201d Aaron said.\nJuniper also expanded Marvis\u2019s capabilities to help with video problems by adding support for Zoom calls. Marvis can now pull data from Zoom clients and the Zoom cloud and correlate it with network-specific insights to determine the root cause of a bad video experience, Aaron said.\u00a0\nIn addition, Marvis learns what causes poor Zoom experiences over time, allowing it to understand trends and identify anomalies for proactive and predictive root-cause identification and correction. This gives IT teams an edge in reducing the mean time to repair Zoom issues, and, in many instances, it can reduce Zoom support tickets entirely, according to a blog from Juniper\u2019s senior director of product marketing Christian Gilby.\nChatGPT and Zoom integration support is available now with a standard Marvis VNA cloud subscription.\nIn addition to expanding Marvis, Juniper added a network access control (NAC) security service to Mist called Access Assurance.\u00a0Juniper Mist Access Assurance includes network admission controls using the secure 802.1X standard and looks at user\/device identity, role and location context to allow for identity-based micro-segmentation and policy assignment.\nWith Access Assurance, customers can enforce secure network authentication and authorization without the challenges associated with the typical on-premises NAC that can require hardware and lots of administration, said\u00a0Sudheer Matta, group vice president of products at Juniper.\n\u201cNetwork administrators often fear their own legacy NAC solutions because they are built using on-premises overlay hardware, which makes them brittle, complex to deploy and operate, and inherently lacking in both scale and resiliency,\u201d Matta said.\nJuniper Mist Access Assurance solution solves this issue by natively integrating NAC into the network infrastructure, and by leveraging AIOps and a cloud-native architecture to set up and operate access management, policy creation and enforcement from anywhere via a familiar interface, Matta said.\u00a0\nAccess Assurance will let customers automatically add features, security patches and updates without interruptions or service downtime, just like the rest of Juniper\u2019s Mist cloud services, the vendor stated.\u00a0Juniper has also deployed cloud instances of Access Assurance in multiple regional locations to direct authentication traffic to the nearest instance for optimal response time and low latency.\nAccess Assurance works with Juniper\u2019s other cloud-based Assurance 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 WAN gear.\nMist Access Assurance stems from Juniper\u2019s acquisition of WiteSand\u2019s cloud-based NAC security technology in 2022. Juniper has integrated WiteSand technology in the Mist cloud service to provide users a full suite of access control features, including a simple authorization policy framework for onboarding guest, IoT, BYOD and corporate devices.\nPricing for Mist Access Assurance will be based on the number of active clients, and it will be available in the first half of 2023.
