Unfortunately N.K. Shankaranarayanan could not join so we could not use the usual bridge - used different bridge (ONAP OSC Alignment meeting bridge)

 A1-Simulator → RANSIM Kafka messaging


Halil Cakal showed current snapshot of A1-SIM → RANSIM (kafka)

  • Need configurable lookup table (Map) for
    • A1 Policy Type  :-:  Topics (req & resp)
  • Need 2 topics: request and response
    • RANSIM will query A1-SIM (adapter) to request lookup table - per A1 Policy Type
    • Each message A1-Sim → RanSIM will have a requestID Key - which must be included in the reply RanSIM → A1-SIM to correlate requests & responses.
      • Default timeout 30 sec waiting for response.
  • Need Near-RT-RIC ID in each message A1 Sim → RanSIM   
    • Can be ignored by RANSIM - as RANSIM acts as 1 near-RT-RIC, so 1:1:1 mapping A1-SIM :  RANSIM : nearRTRIC
  • Next week will demo a real A1 Policy Type (prefer the actual use case type) with full end-to-end sequence
    • (request) curl/postman → A1(REST) → A1-SIM → kafkaAdapter → kafka broker → RANSIM(stub) 
    • (response) RANSIM(stub) → kafka broker → kafka adapter → A1-SIM → A1(REST) → curl/postman
