At the application layer, we assume the existence of a single flow in the network, the one whose throughput is being computed.
We present a model to compute achievable throughput along a path, taking into account Intra-path interference, assuming a saturated source of traffic at the source of the flow.
As explained later, the model can be extended to take into account Inter-path interference from other flows in the network as long as paths taken by the flows do not have any nodes in common.
