Detailed Description

The DtForwarderPingProcessor class consists of filters for ForwarderPing messages for forwarder nodes.

The Ping algorithm allows a node or an RTI Exec to determine whether a path exists to a specified downstream node (NOTE: - currently does not handle pinging federates, but this could be added)

Default Ctor.

virtual DtForwarderPingProcessor::~DtForwarderPingProcessor ( )

virtual

Default Dtor.

Member Function Documentation

virtual bool DtForwarderPingProcessor::gotMsgToLanPort	(	const DtInetAddrAndPort &	src,
		const DtForwarderPingMsg &	msg
	)

virtual

Got Ping Message at the IN Port, drop the message at IN to LAN processor.

virtual bool DtForwarderPingProcessor::gotMsgToOutPort	(	const DtInetAddrAndPort &	src,
		const DtForwarderPingMsg &	msg
	)

virtual

Got Ping Message from the IN or LAN Port to the OUT Port.

virtual bool DtForwarderPingProcessor::ignorePingMsgToLan	(	const DtInetAddrAndPort &	src,
		DtForwarderPort::DtAddressPortList &	destinations
	)

virtual

Ping messages are never forwarded out the LAN port and will be filtered out by gotMsgToLanPort anyway, so there's no destination processing necessary.

This method is just a dummy for the filter ctor.

static int DtForwarderPingProcessor::lostConnection	(	const MAKRti::DtString &	connName,
		const MAKRti::DtString &	hostName,
		unsigned int	connID,
		const std::pair< DtInetAddrAndPort, DtInetAddrAndPort > &	connAddr,
		void *	usr
	)

static

Connection loss callback.

virtual int DtForwarderPingProcessor::lostConnection	(	const MAKRti::DtString &	connName,
		const MAKRti::DtString &	hostName,
		unsigned int	connID,
		const std::pair< DtInetAddrAndPort, DtInetAddrAndPort > &	connAddr
	)

protectedvirtual

Connection loss callback.

virtual bool DtForwarderPingProcessor::processInToOutMsg	(	const DtInetAddrAndPort &	src,
		const DtForwarderPingMsg &	msg
	)

protectedvirtual

Got ping Message from the IN Port to the OUT Port.

virtual bool DtForwarderPingProcessor::processLanToOutMsg	(	const DtInetAddrAndPort &	src,
		const DtForwarderPingMsg &	msg
	)

protectedvirtual

Got ping Message from the LAN Port to the OUT Port.

virtual bool DtForwarderPingProcessor::processPingMsgDestinations	(	const DtInetAddrAndPort &	src,
		DtForwarderPort::DtAddressPortList &	destinations
	)

virtual

Set forwarding destination list based on source (eg.

which inlet the message was received on) and forwarder network configuration

virtual void DtForwarderPingProcessor::sendResponseMsg	(	unsigned long	target,
		DtForwarderPingMsg::DtPingStatus	status,
		const DtInetAddrAndPort *	addr = `0`
	)

protectedvirtual

Send a ping Response based on aggregating all Local responses and all downstream WAN responses.
