Detailed Description

A trace based streamer.

sends udp packets based on a trace file of an MPEG4 stream trace files could be downloaded form : http://www.tkn.tu-berlin.de/research/trace/ltvt.html (the 2 first lines of the file should be removed) A valid trace file is a file with 4 columns: -1- the first one represents the frame index -2- the second one indicates the type of the frame: I, P or B -3- the third one indicates the time on which the frame was generated by the encoder -4- the fourth one indicates the frame size in byte if no valid MPEG4 trace file is provided to the application the trace from g_defaultEntries array will be loaded.

Constructor & Destructor Documentation

ns3::UdpTraceClient::UdpTraceClient	(	Ipv4Address	ip,
		uint16_t	port,
		char *	traceFile
	)

creates a traceBasedStreamer application

Parameters:

	dataSize	ip the destination ip address to which the stream will be sent
	port	the destination udp port to which the stream will be sent
	traceFile	a path to an MPEG4 trace file formatted as follows: FrameNo Frametype Time[ms] Length [byte] FrameNo Frametype Time[ms] Length [byte] ...

Member Function Documentation

virtual void ns3::UdpTraceClient::DoDispose

(

void

)

[protected, virtual]

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Application.

uint16_t ns3::UdpTraceClient::GetMaxPacketSize

(

void

)

Returns:

the maximum packet size

static TypeId ns3::UdpTraceClient::GetTypeId

(

void

)

[static]

This method returns the TypeId associated to ns3::UdpTraceClient.

This object is accessible through the following paths with Config::Set and Config::Connect:

• /NodeList/[i]/ApplicationList/[i]/$ns3::UdpTraceClient

Attributes defined for this type:

• RemoteAddress: The destination Ipv4Address of the outbound packets
  • Set with class: Ipv4AddressValue
  • Underlying type: Ipv4Address
  • Initial value: 102.102.102.102
