Introduction

Juniper BNG CUPS disaggregates the broadband network gateway (BNG) function running in Junos OS into separate control plane and user plane components. The control plane is a cloud-native application that runs in a Kubernetes environment. The user plane component continues to run on Junos OS on a dedicated hardware platform.

In Juniper BNG CUPS, the BNG functions are split into the BNG CUPS Controller (control plane) functions and the BNG User Plane (user plane) functions. The management, state and control packet interfaces operate between the BNG CUPS Controller and the BNG User Planes.

The benefits of Juniper BNG CUPS are the following:

• A centralized BNG CUPS Controller provides for more efficient use of network resources. Following are some examples:
  • Address allocation
  • Load balancing
  • Management and control
• Increased scale—The cloud environment that Juniper BNG CUPS utilizes, enables you to increase the number of subscribers supported.
• Locational independence and separate life-cycle management and maintenance.
• Throughput and latency optimization—Because the BNG User Planes are closer to the subscribers, throughput and latency is optimized.

These release notes accompany the following Juniper BNG CUPS releases:

• Juniper BNG CUPS Release 23.4R1

• Juniper BNG CUPS Release 23.4R2

They describe new features and known problems.
