C++ definition

Provides UDP socket handling for generic applications.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Used in compound modules

Name	Type	Description
UdpApp	compound module	Generates traffic for a UDP application. The traffic source and traffic sink modules can be built from queueing model elements.

Extends

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

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"rcvd: {numReceived} pks\nsent: {numSent} pks"	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
interfaceTableModule	string
localAddress	string	""
localPort	int	-1
destAddress	string	""
destPort	int
timeToLive	int	-1	If not -1, set the TTL (IPv4) or Hop Limit (IPv6) field of sent packets to this value
dontFragment	bool	false	If true, ask IP to not fragment the message during routing
dscp	int	-1	If not -1, set the DSCP (IPv4/IPv6) field of sent packets to this value
tos	int	-1	If not -1, set the Type Of Service (IPv4) / Traffic Class (IPv6) field of sent packets to this value
multicastInterface	string	""	If not empty, set the multicast output interface option on the socket (interface name expected)
multicastAddresses	object	[]	List of multicast addresses that the application socket joins
receiveBroadcast	bool	false	If true, make the socket receive broadcast packets
joinLocalMulticastGroups	bool	false	If true, make the socket receive packets from all multicast groups set on local interfaces
stopOperationExtraTime	double	-1s	Extra time after lifecycle stop operation finishes
stopOperationTimeout	double	2s	Timeout value for lifecycle stop operation

Properties

Name	Value	Description
class	UdpSocketIo
lifecycleSupport
display	i=block/socket

Gates

Name	Direction	Size	Description
trafficIn	input
trafficOut	output
socketIn	input
socketOut	output

Signals

Name	Type	Unit	Description
packetReceived	inet::Packet
packetSent	inet::Packet

Statistics

Name	Title	Source	Record	Unit	Interpolation Mode	Description
packetReceived	packets received	packetReceived	count, sum(packetBytes), vector(packetBytes)		none
packetSent	packets sent	packetSent	count, sum(packetBytes), vector(packetBytes)		none
