NAME ^

Net::BitTorrent::DHT - Kademlia based Distributed Hash Table

Constructor ^

new ( [ARGS] )

Creates a Net::BitTorrent::DHT object. This constructor should not be used directly.

Methods ^

add_node ( { [...] } )

Adds a single node to the routing table. Expects a hashref with the following keys:

ip

The hostname/IP address of the remote node.

port

The port the remote node has open for DHT.

This is an advanced method and should not (normally) should not be used.

node_id ( )

Get the Node ID used to identify this client in the DHT swarm.

nodes ( )

Returns a list of nodes from the routing table in a format suitable for handing off to add_node( ) one by one.

as_string ( [ VERBOSE ] )

Returns a 'ready to print' dump of the object's data structure. If called in void context, the structure is printed to STDERR. VERBOSE is a boolean value.

Bugs ^

In this alpha, there are a number of places where I break away from the specification. These will all be fixed in a future version.

Notes ^

While bandwidth to/from DHT nodes will probably never be limited like other traffic, in the future, it will be taken into account and "drained" from the rate limiter. If there's a burst of DHT traffic, the peer traffic may be limited to avoid the total to exceed the global limit.
