      Description

      Changes in adapter to send all the relevant BW parameters to agent to derive the appropriate TCONT type.

      Guaranteed BW = Fixed BW + Assured BW

      Maximum BW = Fixed BW + Assured BW + Excess BW

       

      Let’s call Fixed BW = GIR, Assured BW = CIR, Max BW = PIR

      Let’s leave GIR and PIR as they are currently defined and redefine CIR as the assured BW.

      If we send these three parameters to the agent along with additional_bw_eligibility:

       

      For Type-1: If GIR > 0, GIR = PIR, additional_bw_eligibility = none -> set guaranteed_bw = maximum_bw = CBR_RT_BW (or CBR_NRT_BW) = GIR and alloc_type=none and send these parameters to BAL.  (alloc_type is inferred from the other parameters)

      For Type-2: If GIR = 0, CIR > 0, CIR = PIR, additional_bw_eligibility = none -> set guaranteed_bw = maximum_bw = CIR, CBR_RT_BW = 0 and CBR_NRT_BW = 0 and alloc_type = NSR and send these parameters to BAL. (alloc_type is set to NSR by default)

      For Type-3: If GIR = 0, CIR > 0, PIR > CIR,  additional_bw_eligibility = none_assured -> set guaranteed_bw = CIR, maximum_bw = PIR, CBR_RT_BW = 0 and CBR_NRT_BW = 0 and alloc_type = NSR and send these parameters to BAL. (alloc_type is set to NSR by default)

      For Type-4: if GIR = 0, CIR = 0, PIR > 0, additional_bw_eligibility = best_effort -> set guaranteed_bw = 0, maximum_bw = PIR, CBR_RT_BW = 0 and CBR_NRT_BW = 0 and alloc_type = NSR and send these parameters to BAL. (alloc_type is set to NSR by default)

      For Type-5: if GIR > 0, PIR >= GIR + CIR, additional_bw_eligibility = non_assured or best_effort -> set guaranteed_bw = GIR+CIR, maximum_bw = PIR, CBR_RT_BW (or CBR_NRT_BW) = GIR and alloc_type = NSR and send these parameters to BAL. (alloc_type is set to NSR by default)
