Detailed Description

NDN tracer for cache performance (hits and misses)

Definition at line 70 of file ndn-cs-tracer.h.

Constructor & Destructor Documentation

ns3::ndn::CsTracer::CsTracer ( boost::shared_ptr< std::ostream >  os,
Ptr< Node >  node 
)

Trace constructor that attaches to the node using node pointer.

Parameters
osreference to the output stream
nodepointer to the node

Definition at line 207 of file ndn-cs-tracer.cc.

ns3::ndn::CsTracer::CsTracer ( boost::shared_ptr< std::ostream >  os,
const std::string &  node 
)

Trace constructor that attaches to the node using node name.

Parameters
osreference to the output stream
nodeNamename of the node registered using Names::Add

Definition at line 222 of file ndn-cs-tracer.cc.

Member Function Documentation

void ns3::ndn::CsTracer::Destroy ( )
static

Explicit request to remove all statically created tracers.

This method can be helpful if simulation scenario contains several independent run, or if it is desired to do a postprocessing of the resulting data

Definition at line 57 of file ndn-cs-tracer.cc.

void ns3::ndn::CsTracer::Install ( const NodeContainer &  nodes,
const std::string &  file,
Time  averagingPeriod = Seconds (0.5) 
)
static

Helper method to install tracers on the selected simulation nodes.

Parameters
nodesNodes on which to install tracer
fileFile to which traces will be written. If filename is -, then std::out is used
averagingPeriodHow often data will be written into the trace file (default, every half second)
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable

Definition at line 107 of file ndn-cs-tracer.cc.

void ns3::ndn::CsTracer::Install ( Ptr< Node >  node,
const std::string &  file,
Time  averagingPeriod = Seconds (0.5) 
)
static

Helper method to install tracers on a specific simulation node.

Parameters
nodesNodes on which to install tracer
fileFile to which traces will be written. If filename is -, then std::out is used
averagingPeriodHow often data will be written into the trace file (default, every half second)
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable

Definition at line 151 of file ndn-cs-tracer.cc.

Ptr< CsTracer > ns3::ndn::CsTracer::Install ( Ptr< Node >  node,
boost::shared_ptr< std::ostream >  outputStream,
Time  averagingPeriod = Seconds (0.5) 
)
static

Helper method to install tracers on a specific simulation node.

Parameters
nodesNodes on which to install tracer
outputStreamSmart pointer to a stream
averagingPeriodHow often data will be written into the trace file (default, every half second)
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable

Definition at line 191 of file ndn-cs-tracer.cc.

void ns3::ndn::CsTracer::InstallAll ( const std::string &  file,
Time  averagingPeriod = Seconds (0.5) 
)
static

Helper method to install tracers on all simulation nodes.

Parameters
fileFile to which traces will be written. If filename is -, then std::out is used
averagingPeriodHow often data will be written into the trace file (default, every half second)
Returns
a tuple of reference to output stream and list of tracers. !!! Attention !!! This tuple needs to be preserved for the lifetime of simulation, otherwise SEGFAULTs are inevitable
