PO-MPTCP: Priorities-Oriented Data Scheduler for Multimedia Multipathing Services

Algorithm 3

PBPD-based data scheduling algorithm.

Definition:

: the priority of data stream list perceived by DPAM

: the priority information for th data stream

: a preferred path list obtained by MDPS

: the first path of

: a candidate path used for prioritized data delivery

When the send buffer is idle and can send packets,

for all within the do

if==1 then

there is a prioritized packet to send

set =

while the cwnd of is full do

set =→ next

end while

else then

using standard MPTCP data schedule to distribute

end if

schedule the packet over

end for
