NL_I_PacketUDPIntraNet

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

Calling Sequence

[Net,R] = NL_I_PacketUDPIntraNet(I,P,Net,R)

Arguments

I :

Node index.

P :

UDP packet.

Net :

Network matrix.

R :

Packet manager.

Description

NL_I_PacketUDPIntraNet performs the displacement of the UDP packet P towards the buffer of the node I of the reception network Net. R corresponds to the packet manager.
