Feature Description

This is an enhancement to optimize GTPC messages between SMF and cnSGW-C across IMS and data racks clusters.

When you perform GR-setup activities with SMF and cnSGW-C, the GTPC message handling can be optimized between these two racks, as in the following scenarios:

  • The set of IPC messages from cnSGW-C to SMF service pods flow over gtpc-ep pods twice leading to message encoding and decoding overheads.

  • Within a GR pair, these IPC messages can avoid one more processing step, if service pods such as cnSGW-C and SMF can route messages to the corresponding peer GTPC nodes directly.

Before applying the configuration for enabling GTPC IPC on cnSGW or SMF interfaces, you must apply inter-rack routing networks using cluster sync. More configuration required to add BGP routes for supporting new routable networks across rack servers.
