Detailed Description

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

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

Only map file (.cch) is supported

In addition to reading specified topology from the .cch file, this class divides nodes into three categories:

client nodes (nodes with degrees less or equal to RocketfuelParams.clientNodeDegrees
gateway nodes (nodes that directly connected to client nodes)
backbone nodes (all the rest)

As some of the .cch files do not give a connected network graph, this reader also allows to keep only the largest connected network graph component.

Member Function Documentation

NodeContainer ns3::RocketfuelMapReader::Read ( void )

virtual

Deprecated call.

Read (RocketfuelParams params, bool keepOneComponent=true, bool connectBackbones=true) should be used instead

Reimplemented from ns3::AnnotatedTopologyReader.

Definition at line 77 of file rocketfuel-map-reader.cc.

NodeContainer ns3::RocketfuelMapReader::Read	(	RocketfuelParams	params,
		bool	keepOneComponent = `true`,
		bool	connectBackbones = `true`
	)

virtual

Main topology reading function.

Parameters

params	parameters specifying range from which link bandwidths and delays should be assigned
keepOneComponent	if true, then only the largest connected component will be kept
connectBackbones	if true, then extra links will be added to ensure connectivity of estimated backbone

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)
