Detailed Description

Topology file reader (extension of Rocketfuel-format type).

http://www.cs.washington.edu/research/networking/rocketfuel/

Only weights and latencies file is supported

Member Function Documentation

NodeContainer ns3::RocketfuelWeightsReader::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.

Returns
the container of the nodes created (or empty container if there was an error)

Reimplemented from ns3::AnnotatedTopologyReader.
