Detailed Description

This Service provides a Lookup service for node and group EIDs in a bittorrent DHT. It is fully event driven. It provides the following mechanisms: Publishes the own EID to the DHT, also as specific neighbour EIDs. Registers for Routing Events to look up automatically for the embedded EIDs in the DHT Adds the found EID with its Convergence Layers as a Node. Adds routes to the neighbour EIDs of the found EID. Uses IPND to announce the DHT name service to local neighbour nodes.

void dtn::dht::DHTNameService::__cancellation	(	)
throw	(
	)

protectedvirtual

returns true

Implements dtn::daemon::IndependentComponent.

Definition at line 57 of file DHTNameService.cpp.

void dtn::dht::DHTNameService::componentDown	(	)
throw	(
	)

protectedvirtual

Calls the interrupt pipe to exit the main loop. And so ends up the main loop indirectly

Implements dtn::daemon::IndependentComponent.

Here is the call graph for this function:

void dtn::dht::DHTNameService::componentRun	(	)
throw	(
	)

protectedvirtual

Runs the bootstrapping method and starts the DHT. Executes the main loop with dtn_dht_periodic. After exiting the main loop, the DHT is shut down.

Implements dtn::daemon::IndependentComponent.

	)

protectedvirtual

Reads the configured settings for the DHT and initializes all needed sockets(IPv4&IPv6) for the DHT

Implements dtn::daemon::IndependentComponent.

Here is the call graph for this function:

const std::string dtn::dht::DHTNameService::getName ( ) const

virtual

Returns the name of this Service: "DHT Naming Service"

Implements dtn::daemon::Component.

		DiscoveryBeacon &	beacon
	)
throw	(	dtn::net::DiscoveryBeaconHandler::NoServiceHereException
	)

virtual

this method updates the given values for discovery service It publishes the port number of the DHT instance

Reimplemented from dtn::net::DiscoveryBeaconHandler.
