Member Function Documentation

bool dtn::routing::ForwardingStrategy::neighborDPIsGreater ( const DeliveryPredictabilityMap &  neighbor_dpm,
const dtn::data::EID &  destination 
) const

checks if the deliveryPredictability of the neighbor is higher than that of the destination of the bundle.

Here is the call graph for this function:

void dtn::routing::ForwardingStrategy::setProphetRouter ( ProphetRoutingExtension *  router)

Set back-reference to the prophet router

virtual bool dtn::routing::ForwardingStrategy::shallForward ( const DeliveryPredictabilityMap &  neighbor_dpm,
const dtn::data::MetaBundle &  bundle 
) const
pure virtual

The prophetRoutingExtension calls this function for every bundle that can be forwarded to a neighbor and forwards it depending on the return value.

Parameters
neighborthe neighbor to forward to
bundlethe bundle that can be forwarded
prophet_routerReference to the ProphetRoutingExtension to access its parameters
Returns
true if the bundle should be forwarded

Implemented in dtn::routing::ProphetRoutingExtension::GTMX_Strategy, and dtn::routing::ProphetRoutingExtension::GRTR_Strategy.
