RtpApplication¶

simple module RtpApplication

An application which uses RTP. It acts as a sender if the parameter fileName is set, and as a receiver if the parameter is empty.

Usage diagram¶

Inheritance diagram¶

Used in compound modules¶

Name	Type	Description
RtpHost	compound module	A network node with Real-time Transport Protocol (RTP) support. Extends StandardHost by adding RTP-specific components for real-time multimedia streaming applications.

Extends¶

Name	Type	Description
SimpleModule	simple module	Base module for all INET simple modules.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
commonName	string		The common name (CNAME) of this host
profileName	string		Which rtp profile is to be used (usually RtpAvProfile)
bandwidth	double		Bandwidth in bytes per second for this session
destinationAddress	string		Destination address (the L3AddressResolver class is used to resolve the address)
portNumber	int		Used port
fileName	string		Filename of file to be transmitted, “” means this system acts only as a receiver
payloadType	int		Payload type of file to transmit
sessionEnterDelay	double		Delay before starting a new session
transmissionStartDelay	double		Delay before starting transmission (related to “sender module created”)
transmissionStopDelay	double		Delay before stopping transmission (related to “start transmission”)
sessionLeaveDelay	double		Delay before leaving session (related to “file transmission finished/stopped” or “session entered” when fileName is “”)

Properties¶

Name	Value	Description
class	RtpApplication
display	i=block/app
selfMessageKinds	inet::RtpAppSelfMsgKinds	Kind used in self messages
