Solution for tracking, monitoring, and managing various devices and services in a distributed environment

 

Keysight Distributed Infrastructure (KDI) is a comprehensive solution that ensures seamless and secure communication within a dedicated network environment called the KDI Fabric. It allows for effectively tracking, monitoring, and managing devices and applications in distributed environments. By leveraging KDI, organizations can optimize performance, enhance visibility, and streamline operations across their distributed infrastructure. 

In a KDI Fabric, KDI Root is a node equipped with KDI Root software that takes charge of secure communication, connecting, and overseeing all other KDI Leaf nodes. It serves as the central control point for managing the fabric through a user-friendly tool, KDI Management UI. On the other hand, a KDI Leaf node represents any device, be it an instrument, a test station, or a PC equipped with the KDI Leaf software enabling them to communicate with KDI Root and facilitating discoverability.

 

Unlock the Power of KDI Fabric:

  1. KDI serves as a control plane, enabling secure connections within the KDI Fabric.
  2. Effortlessly discover and securely connect to KDI Fabric members using the KDI interface.
  3. Create separate communication channels between clients and KDI Fabric members with ease.
  4. Access comprehensive node insights for every device in the KDI Fabric.
  5. Remotely manage KDI-enabled applications on devices within the KDI Fabric.
  6. Ensure the integrity and security of firmware updates, easily pushing them to KDI Fabric members.
  7. Simplify management with the user-friendly KDI Management UI, effortlessly handling local credentials, federated identities, and a comprehensive view of KDI Fabric members and their applications.

Keysight Distributed Infrastructure (KDI) 2024 Update 1

 

New Features:

  • Added functionality for generating and validating tokens from the local node. A KDI node, whether connected to a KDI Root or not can now issue an authentication token for a pin and validate it.
  • Upgraded KDIG to pass tokens to the fabric. The fabric KDIS can now use fine-grained authentication to control access from KDIG.

Enhancements:

  • Added node and fabric information to the KDI management UI when viewing the fabric.

Defect fixes:

  • Fixed incorrect status shown in KDI management UI when viewing KDIG connections.
  • Fixed the lack of feedback in the management UI when the wrong credentials are used or the service is disconnected.
  • Fixed an issue where the KDIS installer could generate an invalid database key.
  • Fixed an issue where failure to re-key the database for upgrades would cause KDIS to become non-functional.

  • Note: During the upgrade process, adminui-realm credentials lacking a corresponding kdim-realm pair will be transitioned to kdim-realm.
  • Additionally, these credentials will be granted the "isAdmin" permission, ensuring a seamless integration of administrative privileges within the unified realm structure.

Enhanced KDI Management UI:

  • New buttons added in the Remote Users screen:
    • Promote - to provide admin access to the federated identities/ remote users
    • Demote - to revoke admin privileges from the federated identities/ remote users
