Sprint:VOLTHA Sprint 1, VOLTHA Sprint 2, VOLTHA Sprint 3, VOLTHA Sprint 4, VOLTHA Sprint 5
Goal:
- Verify support for Tcont type 2 and 3
- Verify the non-assured BW from tcont type 3 is bequeathed to type2 as needed.
ONU: ONU1 and ONU2
Workflow: TT
Services involved: VoD of ONU1 (tcont type2) and VoD of ONU2 (tcont type 3)
Additional BW Indicator:
- None for VoD TP of ONU1(set “additional_bw” in the “us_scheduler” of the VoD TP to “AdditionalBW_None”)
- Non-assured for VoD TP of ONU2(set “additional_bw” in the “us_scheduler” of the VoD TP to “AdditionalBW_NA”)
BW Profile:
- Set the “upstreamBandwidthProfile” value in the SADIS config to “TCONT_TYPE2_500Mbps_Assured_ForVoD” for the VoD service of ONU1.
{ "id": "TCONT_TYPE2_500Mbps_Assured_ForVoD", "pir": 500000, "pbs": 10000, "cir": 500000, "cbs": 10000, "gir": 0 }
- Set the “upstreamBandwidthProfile” value in the SADIS config to “TCONT_TYPE3_700Mbps_Peak_500Mbps_Assured_ForVoD” for the VoD service of ONU2.
{ "id": "TCONT_TYPE3_700Mbps_Peak_500Mbps_Assured_ForVoD", "pir": 700000, "pbs": 10000, "cir": 500000, "cbs": 10000, "gir": 0 }
Verify:
Pump 1Gbps in the upstream from the RG of ONU2 for VoD service and verify that no more than 700Mbps is received at the BNG.
Now pump 500Mbps from the RG of ONU1 for the VoD service and verify that close to 500Mbps is received at the BNG. Also verify that the VoD rate is now truncated to 500Mbps at BNG for ONU2.
This test verifies that non-assured BW is bequeathed to assured BW on the PON upstream as needed.
