For the operational performance evaluation, we use the 50 million UE dataset to emulate large-scale policy provisioning.
We measure end-to-end latency, covering the entire process from the initial UDR query to the generation of a fully encoded URSP.
The testbed consists of PCF and UDR modules communicating over the standard N36 interface, with the UDR implemented using Redis and connected via a 20-gigabit network.
Within the PCF, templates and pre-encoded rules are cached in memory with varying cache coverage.
All experiments are conducted under a sustained load of 1,000 transactions per second, and we report the 99th-percentile latency as the key performance metric. |
