Returns

NodeContainer ns3::RocketfuelTopologyReader::Read ( void )

virtual

Main topology reading function.

This method opens an input stream and reads the Rocketfuel-format file. Every row represents a topology link (the ids of a couple of nodes), so the input file is read line by line to figure out how many links and nodes are in the topology.
