Detailed Description

The netflood module does best-effort flooding.

The netflood primitive sends a single packet to all nodes in the network. The netflood primitive uses polite broadcasts at every hop to reduce the number of redundant transmissions. The netflood primitive does not perform retransmissions of flooded packets and packets are not tagged with version numbers. Instead, the netflood primitive sets the end-to-end sender and end-to-end packet ID attributes on the packets it sends. A forwarding node saves the end-to-end sender and packet ID of the last packet it forwards and does not forward a packet if it has the same end-to-end sender and packet ID as the last packet. This reduces the risk of routing loops, but does not eliminate them entirely as the netflood primitive saves the attributes of the latest packet seen only. Therefore, the netflood primitive also uses the time to live attribute, which is decreased by one before forwarding a packet. If the time to live reaches zero, the primitive does not forward the packet.
