Goal: 

• Verify support for Tcont type 2 and 4
• Verify the BW from tcont type 4 is bequeathed to type2 as needed.

ONU: ONU1

Workflow: TT

Services involved: VoD and HSIA

Additional BW Indicator: 

• None for VoD TP(set “additional_bw” in the “us_scheduler” of the VoIP TP to “AdditionalBW_None”)
• BestEffort for HSI TP(set “additional_bw” in the “us_scheduler” of the HSI TP to “AdditionalBW_BestEffort”)

BW Profile: 

 

• Set the “upstreamBandwidthProfile” value in the SADIS config to “TCONT_TYPE2_500Mbps_Assured_ForVoD” for the VoD service.

     

{         "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_TYPE4_1Gbps_Peak_User1_HSI_Upstream” for the HSI service.

 

  

{        "id": "TCONT_TYPE4_1Gbps_Peak_User1_HSI_Upstream",        "pir": 1000000,        "pbs": 10000,        "cir": 0,        "cbs": 0,        "gir": 0   }

Verify:

Pump 1Gbps in the upstream from the RG for HSI service and verify that no more than 1Gbps is received at the BNG.

Now pump 500Mbps from the RG for the VoD service and verify that close to 500Mbps is received at the BNG. Also verify that the HSI rate is now truncated to 500Mbps at BNG.

 

This test verifies that 500Mbps is assured on the upstream PON BW as needed.
