[p2p-hackers] JDHT: Java Distributed Hash Table

[Aaron Harwood]

Hi Ali and others,

JDHT looks nice. We have a similar development called OPeN in the C++  
world.

Some of the nice things about the OPeN architecture is that the  
service is distinct from the protocol.
Thus we can mix and match different services with different protocols.

In the OPeN architecture, using C++, we have this kind of interface:

char *key,*data;
OpenManager open_manager;
open_manager.OpenInitialize(argc, argv, env );
DataService *data_service = (DataService*) open_manager.GetService 
("DataService", "DefaultDHT");

.
.
.

data_service->Put(key, data)

.
.
.

cout << data_service->Get(key)

.
.
.

data_service->Delete(key);

A second node connects to the first node when the service is  
initialized in the second node. Actually IP/port of
existing peer is given in a configuration file / environment  
variable / command line / application UI, etc.
