Algorithm 3: BA-MPCUBIC: PL_filter

Initialization:

last_packet_loss_time = 0

PL_filter = 0

Upon reception of ACK:

PL_filter = false

last_packet_loss_time = system_current_time

PL_filter_period = system_current_time − (3 × RTTmax)

for all subflow i do

if last_packet_loss_time_of_SFi > PL_filter_period then

PL_filter = true

end if

end for

return PL_filter
