+<h1 id="rsa-remote-service-admin">RSA (Remote Service Admin)<a class="headerlink" href="#rsa-remote-service-admin" title="Permanent link">¶</a></h1>
+<p>The Aries Remote Service Admin (RSA) project allows to transparently use OSGi services for remote communication.
+OSGi services can be marked for export by adding a service property <code>service.exported.interfaces=*</code>. Various other properties
+can be used to customize how the service is to be exposed.</p>
+<p>For more information, check out section "122 JPA Service Specification
+Version 1.0" in the "OSGi Service Platform Enterprise Specification,
+Release 4, Version 4.2" available for public download from the <a href="http://www.osgi.org/Download/Release4V43">OSGi Alliance</a>.</p>
+<h2 id="architecture">Architecture<a class="headerlink" href="#architecture" title="Permanent link">¶</a></h2>
+<p><img alt="Remote Service Admin Architecture overview" src="https://cwiki.apache.org/confluence/download/attachments/30739778/remote-service-admin-spec.png?version=2&modificationDate=1362365400000&api=v2" /></p>
+<h3 id="some-definitions">Some definitions<a class="headerlink" href="#some-definitions" title="Permanent link">¶</a></h3>
+<ul>
+<li>EndpointDescription Describes a remote service using service interfaces, remote url and all other properties to import the remote service.</li>
+<li>EndpointListener a service that is to be notified when remote Endpoints described by OSGi filters appear or disappear.</li>
+</ul>
+<h3 id="topology-manager"><a href="https://github.com/apache/aries-rsa/tree/master/topology-manager">Topology Manager</a><a class="headerlink" href="#topology-manager" title="Permanent link">¶</a></h3>
+<ul>
+<li>Listens to local services and decides which to expose. It can also add properties to change the way services are exposed.
+ For the services to be exported it calls RemoteServiceAdmin.exportService to do the actual export. Then notifies EndpointListeners
+ about the new Endpoint.</li>
+<li>Listens for service requests from consumers and creates EndpointListeners for these interests.</li>
+</ul>
+<p>The TopologyManager by default exposes all suitably marked local services for export and imports all service interests with matching
+remote Endpoints.</p>
+<p>It is the best place to implement system wide governance rules. Some examples what can be done:</p>
+<ul>
+<li>Enhancing all exposed remote endpoints with SSL, basic auth, logging</li>
+<li>Exporting OSGi services with annotations for JAX-WS or JAX-RS even when not specially marked for export</li>
+</ul>
+<p>According to its role the TopologyManager of course does not directly implement the enhancements above. It simply creates the necessary
+calls to a suitable RemoteServiceAdmin.</p>
+<h3 id="remote-service-admin"><a href="https://github.com/apache/aries-rsa/tree/master/rsa">Remote Service Admin</a><a class="headerlink" href="#remote-service-admin" title="Permanent link">¶</a></h3>
+<p>Is called by the Topology Manager to expose local services as remote endpoints and create local proxy services as clients for
+remote endpoints.</p>
+<p>Aries RSA has a custom SPI <a href="https://github.com/apache/aries-rsa/blob/master/spi/src/main/java/org/apache/aries/rsa/spi/DistributionProvider.java">DistributionProvider</a> that allows to easily create new transports and serializations.
+Existing providers are:</p>
+<ul>
+<li><a href="http://cxf.apache.org/distributed-osgi.html">CXF</a> (JAXRS, JAXWS)</li>
+<li><a href="https://github.com/apache/aries-rsa/tree/master/provider/tcp">TCP</a> (Light weight Java Serialization over TCP)</li>
+</ul>
+<h3 id="discovery">Discovery<a class="headerlink" href="#discovery" title="Permanent link">¶</a></h3>
+<p>A discovery implementation uses EndpointListeners to listen for local Endpoints and publishs them for other containers.
+It also listens to remote Endpoints and notifies EndpointListeners about their presence.</p>
+<p>Existing implementations:</p>
+<ul>
+<li><a href="https://github.com/apache/aries-rsa/tree/master/discovery/local">Local discovery</a> using xml descriptors</li>
+<li><a href="https://github.com/apache/aries-rsa/tree/master/discovery/zookeeper-server">Zookeeper based discovery</a></li>
+</ul>
+<h2 id="a-simple-example-using-apache-karaf">A simple example using Apache Karaf<a class="headerlink" href="#a-simple-example-using-apache-karaf" title="Permanent link">¶</a></h2>
+<p>See <a href="https://github.com/apache/aries-rsa/tree/master/examples/echotcp">EchoTCP example</a>. Follow the Readme to install the example in Apache Karaf.</p>
+<p>The EchoTCP example implements a simple echo service that can be called remotely.
+The example uses declarative services to publish and bind services.</p>
+<h3 id="modules">Modules<a class="headerlink" href="#modules" title="Permanent link">¶</a></h3>
+<ul>
+<li>api : EchoService interface</li>
+<li>service : EchoService implementation</li>
+<li>consumer : Small consumer that uses the EchoService</li>
+</ul>
+<p>The example installation uses the tcp transport to do the remoting but the example code is not tied to any transport.</p></div>
