NARVAL_I_SendTcpInter

Perform the displacement of a TCP packet from an emission network matrix towards an reception network matrix.

Calling Sequence

[net,nets,rp,swi,rti] = NARVAL_I_SendTcpInter(ni,p,bs,net,nets,rp,t,swi,rti,rtmax)

Parameters

ni :

node index.

p :

TCP packet.

bs :

buffer size.

net :

reception network matrix.

nets :

emission network matrix.

rp :

packet manager.

t :

current time.

swi :

sliding window of each network node.

rti :

retransmission time of each network node.

rtmax :

maximum value of the retransmission time parameter.

Description

NARVAL_I_TcpPacketIntra performs the displacement of the TCP packet already located inside the buffer of the node ni of the emission network nets towards 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.
