If you develop with Odysseus and checked out its sourcecode, you can start OdysseusNet by adding the plugin (if you're developing with the monolithic version of Odysseus) or the plugin (server-version of Odysseus) to your product- or launch-definitions. These features contain all underlying OdysseusNet-Features currently available. A more detailed description which feature encapsulates which function can be found in Underlying Features of OdysseusNet.

Network structure of OdysseusNet: OdysseusNodes and NodeGroups

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 A OdysseusNode is a machine running Odysseus with OdysseusNet installed and activated. Each node has a human-readable non-unique name (set in the Configuration) and a generated unique NodeID (needed for developers).

By default, two nodes are connecting to each-other if they are physically reachable (e.g., LAN), forming a network of interconnected Odysseus-Instances. To divide the network in logical subnetworks, each OdysseusNode can be assigned to a NodeGroup. Only nodes, which are in the same group, are connected and can communicate with each-other. By default, each OdysseusNode is in the same group (called OdysseusGroup). However, this can be changed in the Configuration of OdysseusNet.

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).


The user can execute the Console Command startOdysseusNet to start OdysseusNet in the console (useful in the server-version of Odysseus).  Alternatively, it is possible to start OdysseusNet automatically when Odysseus is started (see Configuration of OdysseusNet).

To finally stop OdysseusNet, the user has to click the button in the toolbar of the NodeView again or , execute the console command stopOdysseusNetstopOdysseusNet or has to stop Odysseus entirely.

Features of OdysseusNet

OdysseusNet as a feature is the sum of multiple smaller OdysseusNet features. Each of them encapsulates specific functions, possibilities and interfaces, all useful for "typical" Odysseus-Users and Odysseus-Developers. A (not complete) list of features is as follows:
