The manager informs the network bundle about End Points - * that it creates. The network bundles then uses a protocol like - * SLP to announce these local end-points to the network. - * - * If the network bundle discovers a new Endpoint through its discovery - * protocol, then it sends an End Point Description to all the End Point - * Listener services that are registered (except its own) that have specified an - * interest in that endpoint. - * - * Endpoint Listener services can express their scope with the service - * property {@link #ENDPOINT_LISTENER_SCOPE}. This service property is a list - * of filters. An Endpoint Description should only be given to a Endpoint - * Listener when there is at least one filter that matches the Endpoint - * Description properties. given to it. - * - * This filter model is quite flexible. For example, a discovery bundle is only - * interested in locally originating Endpoint Descriptions. The following filter - * ensure that it only sees local endpoints. - * - * 
- *   (org.osgi.framework.uuid=72dc5fd9-5f8f-4f8f-9821-9ebb433a5b72)
