NARVAL_I_UdpPacketIntra

Perform the displacement of a UDP packet inside a reception network.

Calling Sequence

[net,rp] = NARVAL_I_UdpPacketIntra(ni,p,net,rp)

Parameters

ni :

node index.

p :

UDP packet.

net :

network matrix.

rp :

packet manager.

Description

NARVAL_I_UdpPacketIntra performs the displacement of the UDP packet p towards the buffer of the node ni of the reception network net. rp corresponds to the packet manager.

[swi,rti,network,networks,rp]=NARVAL_I_E2R(swi,rti,rtmax,network,networks,n,bs,rp,t,probroute);//emission of packets on the reception network
ind=find(network(:,$) <> 0);//UDP packets present on the network
i=ind(1);//selection of the first one
p=network(i,1);//first packet
r=rp(p,$);//route followed by this packet

network(i,:)
[j,ack]=NARVAL_I_NextNode(i,path);//calculation of the next node where the packet should be transmitted
j//node where the packet should be propagated
