Feature Description
The cnSGW-C supports the cache pod optimization to reduce the cache pod query at the GTPC endpoint.
The get affinity query is used to receive the affinity information in an outgoing request or response message toward the GTPC endpoint. With this optimization, the GTPC endpoint pod doesn't send the query to the cache pod for the upcoming request messages.
To receive this affinity information, an affinity query is used in an outgoing request or response message toward the GTPC endpoint. With this optimization, the GTPC endpoint pod doesn't send the query to the cache pod for the upcoming request messages.
In the previous releases, after the cnSGW-C sent out the DDN and received the MBR from the MME, the GTPC endpoint had to send the query to the cache pod to get affinity information. Later, the cnSGW-C used the affinity information so that an MBR can be forwarded to the correct service pod.
With this optimization, you can prevent the extra cache pod query.
