How it Works

This section describes how this feature works.

The GR Instance Split or UDP Proxy merge mode is a prerequisite for this feature.

This feature is disabled by default. While configuring this feature, provide separate internal and external VIP addresses for S11 and S5 GTPC endpoints, and deploy two GTPC-EP pods.

On configuring the feature, cnSGW-C sends the IPC call from SMF-service, SGW-service, and the Node Manager to the GTPC pod based on the GTPC interface and the GR instance ID.

The following are the recommendations for the GTPC interface split feature:

  • CPU Core:

    • S5 Interface: 6

    • S11 Interface: 18

    • UDP Proxy: 2

  • VIP Configuration: Separate internal and external VIP for S5 and S11 interfaces

  • The Dispatcher configuration must be the same configuration as existing before upgrade.

The following diagram indicates the GTPC Interface Split pod layout.
