EasyPastry is built on top of
Pastry, a decentralized key-based routing (KBR) P2P overlay network.
The main objective of EasyPastry is to provide a complete façade in
order to simplify the p2p application development.
Moreover, EasyPastry take
the Common API like their own
layered architecture and use the implementations of
Bunshin (DHT) and
Scribe (Cast). A diagram can be seen just below.
Features
* Easy Node Starting: Using
PastryConnection
and a simple xml file.
* Multiple Nodes in Local : Without modify the xml file, we
can start N nodes in the same machine.
* DHT and Cast Abstractions : Using
DHTHandler and
CastHandler we have direct control of these applications.
* Key-Based Routing methods : Unified access to
routing and messaging method via
CastHandler.
* DHT Consistency : What happens if we have a
previous value and then a new value appears for the same key?
DHTHandler dht = DamonCore.getDHTHandler(Context. REGISTRY,
new
ValueMergeClient());
when
class ValueMergeClient
implements
BunshinMergeClient { ... }
and
public
interface
BunshinMergeClient {
public
abstract Object merge(Object
oldObj, Object newObj);
}

eAula
eAula is an Java EE Servlet
Application, which has been developed using
EasyPastry. It benefits from EasyPastry
services, and it is an application for folder and file
sharing across the decentralized web server
(i.e.
Jetty) network.
