Web Live, Virtual and Constructive (WebLVC)

The systems portfolio of the Norwegian Armed Forces should follow service-oriented principles. To achieve cost effective training and be able to use simulations for support in operations, it is important that simulation systems can be a part of the Norwegian Armed Forces’ information infrastructure (INI). An important principle is to give the user easy access to simulation applications, and that applications are available at the location of the user. This report describes a standard that makes it possible for web applications to participate in a distributed simulation. Web Live, Virtual and Constructive (WebLVC) is a new standard under development by the Simulation Interoperability Standards Organization (SISO), which can be used to link web applications with a distributed simulation system that uses either Distributed Interactive Simulation (DIS) or High Level Architecture (HLA). The future standard should be highperformance and be natural to use for web applications. The standard consists of a messaging protocol and a WebLVC-server that links web applications with the simulation system. A demonstrator for the most important parts of the standard has been developed, which shows that is it possible for a web application to participate in a HLA federation using the WebLVC protocol. WebLVC is easy to use for web applications, but seems more complex than necessary to implement on the server side. The standard is still under development, and this report identifies several simplifications that should be considered in the future.
