This is a native Distributed Interactive Simulation (DIS) websockets implementation.

Websockets are Javascript implementations of TCP sockets (plus some extra special sauce.) This enables Javascript running inside an HTML page can send and receive binary DIS messages over TCP. The implications for M&S can be significant; with WebGL this enables 3D graphics inside the web page. Even without 3D graphics many useful applications can be created via web mashups with, for example, Google Maps, Open Street Map, and D3.js graphics.

This distribution uses Jetty (a Java-based web application server similar to Apache Tomcat in functionality) to implement the server side of websockets. The application is configured via the GatewayConfiguration.properties file in the root directory.

Included are web pages that implement a simple Google Maps web page that displays the location of DIS entities. These pages are in the content directory.

This distribution includes a Javascript implementation of DIS that encodes and decodes the standard IEEE binary format. Thus DIS messages from legacy applications can be forwarded to the web page from the server side and decoded there.

There are a number of experimental features you probably shouldn't mess with, including a Redis server for cloud-based distributions that can scale, and an area of interest (AOIM)/distributed data management (DDM) implementation that uses Javascript to filter packets on the server side on a per-connection basis.
