- Guarantee device performance and network quality
- Ensure consistent deployment that saves time and money


The Challenge

Device Life-cycle Management is a critical best practice that operators rely on to maintain their network equipment. The workflow for this process can include installation of device, performance testing, upgrades, configurations, and the eventual dismantling of the device at end of service. All network equipment requires these tasks from shipment arrival to End-of-Life (EOL) disposal.

A recent market guide for network automation tools from Gartner1 shows that 75% of networking activities are still manual today. Device life-cycle management is no exception. Typically, operators have taken either a tedious manual approach to device maintenance or a Do-It-Yourself (DIY) approach with homegrown tools that provide some automation. However, a recent study by Analysys Mason2 shows that 80% of DIY automation implementations fail. Clearly, there is lots of room for improving device life-cycle management with intelligent network automation solutions.

Take the critical task of onboarding, for example. A recent survey from Heavy Reading3 shows that only 16% of CSPs are able to onboard a device in less than one hour. When a typical IP service fabric could require onboarding thousands of access and aggregation devices, field technicians and network operation center engineers could face hundreds of days dedicated to device onboarding.

Not surprisingly, according to the same survey, CSP’s two primary drivers for automation are to reduce the time needed to deploy services and improve productivity. Deploying new equipment is time consuming and error prone due to the required number of manual interventions and the limited ways that operators and service providers validate quality and device integrity during onboarding. Moreover, employing field technicians with the necessary networking expertise and CLI knowledge increases costs.

In the age of artificial intelligence (AI), machine learning (ML), and autonomous networks, device life-cycle management can be easier and more streamlined. Juniper® Paragon Automation allows CSPs to reimagine the process from start of life to EOL. With automation, CSPs can realize these improved processes:

  • The onboarding process should not stop at zero-touch configuration and provisioning. Onboarding should be planned and automated to meet the operational intent, from the moment the device is unboxed to when it is ready for service.
  • Field technicians should be able to deploy services with intuitive processes, without extensive CLI manuals, user documentation, or systems red tape. They should have visual guides and easy, step-by-step instructions at their fingertips. The instructions should guide them to where to insert cables and warn them if a cable is inserted in the wrong port.
  • Device health checks and hardware and software integrity should not be afterthoughts or forgotten. They should be embedded into the onboarding process.
  • End-to-end connectivity tests should be performed automatically on the data plane to ensure performance objectives are met—before a device starts forwarding customer traffic.
  • Operations should not waste cycles reviewing a sea of basic alarms. Monitoring and troubleshooting should be simplified to focus on the KPIs that matter most. Highlighting the critical issues that violate SLAs further speeds problem resolution.
  • Root cause analysis should be established automatically, as problems happen. When insight is available about necessary urgent actions, operators can resolve problems faster.

Device Life-cycle Management with Juniper Paragon Automation

Paragon Automation provides automated, consistent, and secure Device Life-cycle Management that maintains the health of the device for its entire life cycle. It automates onboarding plans, guided device field installations, configuration (including templates and backups), updates, and compliance audits. At the same time, it provides AI-driven monitoring and problem troubleshooting.

Device Life-cycle Management makes it possible for intents to be specified for the field technician procedure during Paragon Automation’s secure, automated device onboarding. The intent model and orchestration design makes the device onboarding process elegantly simple and efficient. With a few steps and explicit guidance for field technicians, device onboarding becomes extremely easy.

Secure, automated device onboarding starts with the design of the intents and intent profiles for new devices. Field technicians initiate the process at the site. Using a mobile phone, the technician signs on to the Paragon Automation field technician application and scans the unique QR code on the network device, which triggers automation specifically for that device.

Juniper routers come pre-integrated with a secure Trusted Platform Module (TPM2.0) chip and unique Device identifier (DevID) that ensures the authenticity and tamper-proofness of the hardware. Once the Paragon Automation application determines authentic Juniper hardware, it provides a step-by- step visual installation guide to make sure that correct pluggables are used and the technician connects each cable correctly.

Field technicians continuously receive status updates and recommended actions when they make an error. After cabling is complete, the correct software image and device configuration are applied automatically. The automation ensures that each peering device’s configuration is also updated appropriately, such as configuring BGP or simply the other link endpoint.

Various validation steps are then performed in the background to ensure the correct hardware and software are installed, the right configurations are loaded successfully, the device meets trust and compliance checks, the device is healthy, and interfaces are up. Connectivity is also performance tested to ensure they meet SLAs. Technicians can then complete the onboarding workflow. In parallel, Paragon Automation updates inventory so devices are fully ready for service in minutes.

During onboarding, the workflow supports multiple steps that simplifies the process. When these steps are automated, devices are onboarded in minutes—much more quickly than a limited, semi-automatic, zero-touch provisioning (ZTP) process that can take hours or even days.

Meanwhile at the network operation center (NOC), Paragon Automation gives engineers full oversight on every onboarding activity happening across the network. Paragon Automation keeps engineering and operation teams in sync with the network state in real time. After the field technician completes the work order, the network is AIOps ready for Day 1 and 2 operations.

Through Paragon Automation’s device onboarding, operators can supervise the field technicians performing onboarding and decide which devices are ready for service. With intuitive, easy- to-use dashboard views, operators can see onboarding-related issues across the network and investigate when needed.

One key challenge in the NOC is making sense of the overwhelming number of events and amount of incoming data. Sifting through it all is tedious and time-consuming for operators. Paragon Automation, using AI and ML, aggregates events and data, focusing it on root causes and urgent actions. It filters the noise so that network operators can identify what is urgent and the actions needed to resolve the issue.

Dashboards provide a quick and simplified at-a-glance view that highlights all the key metrics to the top and identifies the most urgent issues prominently. The NOC engineer can quickly understand which issues to investigate and triage problems for troubleshooting and remediation. Once ready, the engineers can perform remote testing to validate performance objectives. Then, with the click of a button, the engineer can place the network device into service.
