OdysseusNet is a extension for Odysseus which enables distributed data stream processing using a network of interconnected machines (e.g., LANs). It is a follow-up project of OdysseusP2P.
OdysseusNet is a feature which is installed like the other features (see How to install new features). However due to technical limitations, OdysseusNet is (currently) not applicable to the client-version of Odysseus. If you use the server-version, install the OdysseusNet Server Feature. For monolithic Odysseus, install the monolithic version of the OdysseusNet Feature. After restarting Odysseus, OdysseusNet is integrated and ready.
If you develop with Odysseus and checked out its sourcecode, you can start OdysseusNet by adding the plugin
de.uniol.inf.is.odysseus.net.monolithic.feature (if you're developing with the monolithic version of Odysseus) or the plugin
de.uniol.inf.is.odysseus.net.server.feature (server-version of Odysseus) to your product- or launch-definitions. These features contain all OdysseusNet-Features currently available. A more detailed description which feature encapsulates which function can be found in
After starting Odysseus, OdysseusNet is – by default – deactivated. In this case, Odysseus behaves like normal. When OdysseusNet is activated (explained in the next section), the Odysseus-Instance becomes an OdysseusNode. Therefore, a OdysseusNode is a machine running Odysseus with OdysseusNet installed and activated. By default, two nodes are connecting to each-other if they are physically reachable (e.g., LAN), forming a network of interconnected Odysseus-Instances. With this default behaviour, a decentralized and unstructured network of nodes is being built. See the last section of this page if you want to modify this (e.g., establishing master-slave-relationships between nodes).
Only when OdysseusNet is activated, the functionality for distributed data stream processing are available. There are multiple possibilities to activate it. If the graphical user interface OdysseusStudio is available, the user can switch to the OdysseusNet Perspective. There in the NodeView, the user can click on the button in the toolbar in the top-right (marked with red circles in the picture below).
The user can execute the Console Command
startOdysseusNet to start OdysseusNet in the console (useful in the server-version of Odysseus).
To stop OdysseusNet, the user has to click the button in the toolbar of the NodeView again or execute the console command
