\section designOverviewPackages Packages

The Layer Management Service is composed of the following packages:

\li Layer Management
\li One Renderer package
\li One or more Communicator packages

The Layer Management Service component makes use of the following external packages provided by the application framework:
 
\li Renderer and Communicator packages which in turn depend on other packages/frameworks for the communication (e.g. middle ware) or the device dependent rendering (e.g. graphic frameworks)

The diagram below shows the relationships between the packages:
