Perform the displacement of a TCP packet inside a reception network.
[network,rp,swi,rti] = NARVAL_I_TcpPacketIntra(ni,p,network,rp,t,swi,rti,rtmax)
node index.
TCP packet.
reception network matrix.
packet manager.
current time.
sliding window of each network node.
retransmission time of each network node.
maximum value of the retransmission time parameter.
NARVAL_I_TcpPacketIntra performs the displacement of the TCP packet p towards the buffer of the node ni of the reception network net. swi gathers the sliding window of each network node. rti provides the retransmission time of each network node. rtmax corresponds to the maximal retransmission time. rp represents the packet manager. t is the current time.
