Known subclasses

Name	Type	Description
UdpRequestResponseApp	compound module	This module is a generic request/response based server application. For each request it receives, it generates a 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.

Parameters

Name	Type	Default value	Description
interfaceTableModule	string

Unassigned submodule parameters

Name	Type	Default value	Description
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, asks 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.receiveBroadcast	bool	false	if true, makes the socket receive broadcast packets
io.joinLocalMulticastGroups	bool	false	if true, makes the socket receive packets from all multicast groups set on local interfaces
io.stopOperationExtraTime	double	-1s	extra time after lifecycle stop operation finished
io.stopOperationTimeout	double	2s	timeout value for lifecycle stop operation
