Light Weight Event System (LWES)

0.22.2

The LWES Light-Weight Event System is a framework for allowing the exchange of information from many machines to many machines in a controlled, platform neutral, language neutral way. The exchange of information is done in a connectless fashion using multicast or unicast UDP, and using self describing data so that any platform or language can translate it to it's local dialect.

This leads to a system with the following features

Fire and Forget messaging
Decoupling of senders (emitters) from receivers (listeners, journallers)
Centerless, no single point of failure
Support for many to many communication where nodes can enter and leave the system at any time.
Computer language and Hardware Platform independent

The system consists of two major components

Emitter - a source of events, this is usually a server or process which wants to announce something

Listener - a sink of events which deserializes and processes events on the fly as they are received.

There is also a custom listener which defers deserialization until some point in the future, and simply captures and writes the events to a log. This is in the pj package, and is called a journaller.

This library is the 'C' implementations of the LWES. There is also a perl xsubs wrapper, and a pure java implementation packaged separately. All should be wire format compatible.
