4 OCNADD Benchmarking Testing

This section describes the performance testing scenarios and results for the Message Feed functionality provided by Oracle Communications Network Analytics Data Director. The message feed feature is tested with SCP and NRF as the source of the message feed and the benchmarking results are provided in the subsequent sections of this chapter.

Benchmark Test Environment

The deployment specifications for all the NFs are as follows:
  • OCNADD Release 22.0.0 deployed over TANZU platform
  • OCNADD Replication Factor (RF): 1
  • OCNADD Data Feed: HTTP2 (secured and unsecured)
  • OCNADD Kafka PVC: 200GB

    For more information about PVC requirements, see Kafka PVC Storage Requirements.

  • 3rd Party Application: 1 Perfgo Server with 2 End-points
  • cnDBTier Release 22.3.0
  • NRF Release 22.4.0

    Note:

    The Ingress Gateway and Egress Gateway message copy feature must be enabled and the gzip functionality must be disabled in NRF.

  • SCP Release 22.4.0
  • Environment: VMWare TANZU Platform

Benchmark Testcase Specifications

The testcase parameters are as follows:

Note:

1.
  • OCNADD
    • A feed is configured using the OCNADD Console with aggregation rule set to both SCP and NRF2.
    • Ingress Message ingestion rate was 29K MPS, where 20K MPS was coming from SCP and 9K MPS was coming from NRF3.
    • The latency, resource utilization, and MPS is observed for the period of 12 hrs or more.
    • Message Ingestion Rate: 29K MPS
