2 Architecture

This chapter covers the Oracle's 5G SBI Application-Level Traffic Feed solution that demonstrates SBI traffic feed going from Oracle 5G NFs to Oracle Data Director (acting as a traffic feed aggregator).

Following is a high-level block diagram showing the traffic feed from Oracle NFs:

Traffic feed from SCP

The message mirroring takes place through four endpoints covering RxRequest, TxRequest, RxResponse, and TxResponse with respect to SCP and through two endpoints. namely, Ingress and Egress Gateways with respect to Oracle NFs. All transactions are mirrored for both SCP and Oracle NFs.

Solution Overview

Data Director is a solution within the Network Analytics suite, which addresses the 5G traffic feed aggregation and data enrichment. It assimilates the data required to statistical prediction.

Data Director provides the following key features:

  • Correlation and xDR
    • Correlation feature generates xDRs from network transactions, enabling insights.
    • xDRs aid in network troubleshooting, tracing scenarios across NFs, and KPI generation.
    • Enhances network visibility and observability through KPIs and threshold alerts.
    • Enables network efficiency reports via intuitive dashboards.
    • xDRs facilitate advanced descriptive and predictive network analytics.
    • Supports integration with network analytics frameworks like NWDAF or Insight Engine.
  • Aggregation
    • Collects and aggregates the network traffic from multiple NFs, for example, SCP, SEPP, and NRF.
    • Provides the aggregated traffic feed to one or many third-party monitoring tools.
  • Filtering
    • Filtering is supported for selected metadata and header attributes in OCNADD.
    • Delivers only relevant traffic, such as traffic matching specific consumer-id and/or service-name, to the third party tool.

      For more information, see "Data Filtering" and "Data Filters List" sections in Oracle Communications Network Analytics Data Director User Guide.

  • Replication
    • Feeds multiple third-party systems with the collected feed, for example, to the monitoring, troubleshooting, and security tool.
  • Secure Transport (TLS)
    • Provides the data delivery to third-party tools securely.
  • Synthetic Packet Generation
    • Synthetic packet generation in Data Director converts incoming JSON data to network transfer wire format.
    • Supports L3L4 mapping on DD that allows end user to map L3 and L4 information with desired metadata/L7 layer parameters
    • Transfers converted packets securely to 3rd party monitoring probes.
    • Third party probes utilize these synthetic packets for internal monitoring applications.
    • Eliminates the necessity for additional applications by vendors to handle JSON data.
    • Saves critical compute resources and reduces associated costs for vendors.
  • High Availability
    • Data Director is implemented as a Kubernetes service.
    • Multiple Kafka connections from NFs and Data Director are established to stream the ingress data from NFs.
    • Each instance of the Data Director supports two HTTP2 endpoints of the third-party monitoring tools.
    • The number of connections depends on the amount of throughput required.
  • Data Director Network Visibility & KPIs
    • Data Director as a data broker holds network data for generating reports and KPIs.
    • Reports and KPIs via dashboards offer insights and operational support.
    • Generates KPIs for network utilization and load, enhancing visibility.
    • xDRs from correlated messages used for intuitive network efficiency reports.
