Acknowledge a TCP/MPTCP packet inside an emission network matrix and a packet manager.
[Rn,Sn,N,R,Net] = NL_I_PacketsAckNetwork(R,Net,P,S)
Packet manager.
Emission network matrix.
Current packet.
Sliding window.
Route ID followed by P.
Connection source node.
Quantity of packets belonging to the same connection (P) after the acknowledgement.
NL_I_PacketsAckNetwork acknowledges the TCP or MPTCP packet of index P inside the emission network matrix Net. is the current sliding window of the defined connection. The sliding window is shifted to the next packet with the value Ack=0. Thereafter all acknowledged packets must be deleted from the packet manager R.
corresponds to the connection source node.
is the route index followed by P. N represents the quantity of packets of the same connection under consideration after the acknowledgement process. Then it remains N packets that have not yet reached the destination node.
