A generic request/response-based server application. For each request it receives, it generates different traffic based on the data the request contains. The client application can be any source that is capable of generating packets with different data. The first byte of the packet data determines the response traffic, which can be configured to produce complex streams of packets with various data and timing distributions.

Inheritance diagram

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

Extends

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.

Parameters

Name	Type	Default value	Description
interfaceTableModule	string
numKind	int	2

Properties

Name	Value	Description
application
display	i=block/app

Gates

Name	Direction	Size	Description
socketIn	input
socketOut	output

Unassigned submodule parameters

Name	Type	Default value	Description
io.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
io.interfaceTableModule	string
io.localAddress	string	""
io.localPort	int	-1
io.destAddress	string	""
io.destPort	int
io.timeToLive	int	-1	If not -1, set the TTL (IPv4) or Hop Limit (IPv6) field of sent packets to this value
io.dontFragment	bool	false	If true, ask IP to not fragment the message during routing
io.dscp	int	-1	If not -1, set the DSCP (IPv4/IPv6) field of sent packets to this value
io.tos	int	-1	If not -1, set the Type Of Service (IPv4) / Traffic Class (IPv6) field of sent packets to this value
io.multicastInterface	string	""	If not empty, set the multicast output interface option on the socket (interface name expected)
io.multicastAddresses	object	[]	List of multicast addresses that the application socket joins
io.receiveBroadcast	bool	false	If true, make the socket receive broadcast packets
io.joinLocalMulticastGroups	bool	false	If true, make the socket receive packets from all multicast groups set on local interfaces
io.stopOperationExtraTime	double	-1s	Extra time after lifecycle stop operation finishes
io.stopOperationTimeout	double	2s	Timeout value for lifecycle stop operation
