Used in: Controller

• optional int32 channel_1_to_2_bandwidth_bps = 1

  Uplink bandwidth above which the number of encoded channels should switch from 1 to 2.

• optional int32 channel_2_to_1_bandwidth_bps = 2

  Uplink bandwidth below which the number of encoded channels should switch from 2 to 1.

Used in: ControllerManager

• optional Controller.ScoringPoint scoring_point = 1

  The distance from |scoring_point| to a given network condition defines the significance of this controller with respect that network condition. Shorter distance means higher significance. The significances of controllers determine their order in the processing pipeline. Controllers without |scoring_point| follow their default order in |ControllerManager::controllers|.

Used in: Controller

• optional int32 uplink_bandwidth_bps = 1

  |ScoringPoint| is a subspace of network condition. It is used for comparing the significance of controllers.

• optional float uplink_packet_loss_fraction = 2

• repeated Controller controllers = 1

• optional int32 min_reordering_time_ms = 2

  Least time since last reordering for a new reordering to be made.

• optional float min_reordering_squared_distance = 3

  Least squared distance from last scoring point for a new reordering to be made.

Used in: Controller

• optional int32 dtx_enabling_bandwidth_bps = 1

  Uplink bandwidth below which DTX should be switched on.

• optional int32 dtx_disabling_bandwidth_bps = 2

  Uplink bandwidth above which DTX should be switched off.

Used in: Controller

• optional FecController.Threshold fec_enabling_threshold = 1

  |fec_enabling_threshold| defines a curve, above which FEC should be enabled. |fec_disabling_threshold| defines a curve, under which FEC should be disabled. See below packet-loss ^ | | | | | FEC | \ \ ON | FEC \ \_______ fec_enabling_threshold | OFF \_________ fec_disabling_threshold |-----------------> bandwidth

• optional FecController.Threshold fec_disabling_threshold = 2

• optional int32 time_constant_ms = 3

  |time_constant_ms| is the time constant for an exponential filter, which is used for smoothing the packet loss fraction.

Used in: FecController

• optional int32 low_bandwidth_bps = 1

  Threshold defines a curve in the bandwidth/packet-loss domain. The curve is characterized by the two conjunction points: A and B. packet ^ | loss | A| | \ A: (low_bandwidth_bps, low_bandwidth_packet_loss) | \ B: (high_bandwidth_bps, high_bandwidth_packet_loss) | B\________ |---------------> bandwidth

Used in: Controller

• optional float fl_increasing_packet_loss_fraction = 1

  Uplink packet loss fraction below which frame length can increase.

• optional float fl_decreasing_packet_loss_fraction = 2

  Uplink packet loss fraction below which frame length should decrease.

• optional int32 fl_20ms_to_60ms_bandwidth_bps = 3

  Uplink bandwidth below which frame length can switch from 20ms to 60ms.

• optional int32 fl_60ms_to_20ms_bandwidth_bps = 4

  Uplink bandwidth above which frame length should switch from 60ms to 20ms.
