This will start the platform with or without the awareness component. It is also possible to setup an own server using the Relay Standalone Distribution from the downloads section Jadex Pro Only , which allows for building up private platform networks. IP-Scanner discovery disabled per default, local network: Whenever a message is received the message service will forward it to this discovery agent which subsequently announces a new platform. Welcome to the Jadex Active Components 3.

Local discovery enabled per default, local machine: The scanner tries to find out the network type and send awareness infos to IP addresses within the network. If no fresh awareness info is received after this timepoint has passed the management component will delete the proxy with some delay tolerating latencies.
The registry distributes its entries to all platforms. The discovery mechanisms have the task to distribute awareness infos of the own platform and also receive such infos from other platforms. Uses IP broadcast to announce awareness infos.
For these reasons the scanner is deactivated per default. The management part is responsible for creating and deleting proxy components on the local platform whenever changes occur. Broadcast discovery enabled per default, local network: Jadex Active Components 3.

The awareness component is functionally split into a management and a discovery part. For this reason it is beneficial to enable multiple of them bluetootj order to get a robust setup.
Relay discovery enabled per default, global network: To deactivate or activate mechanisms at runtime again subcomponents can be started or stopped. As multicast blluetooth receivers to register at the multicast address this mode does not send packets to other no Jadex nodes in the network. Whenever a message is received the message service will forward it to this discovery agent which subsequently announces a new platform.
Platform Awareness – Jadex Active Components Documentation
The screenshot shows that a component named ‘awa’ exists, which is the default name for the awareness component. For this puropose the awareness settings JCC plugin is available.
At runtime the currently active awareness mechanisms can be seen by looking at the subcomponents of the awareness management component. Having a proxy component of another platform will integrate this remote platform transparently, i. First, the scanner floods the network with messages and second sending out messages to a bunch of network ips is sometimes considered to be an indication for virus behavior. Platform awareness allows for automatic discovery of other platforms in the network.
In Jadex, awareness is introduced by so called proxy components, which are local component representatives of a remote platform.
Bkuetooth a discovery component receives a new awareness info it will forward the info to the management component.
In addition to the global awareness setting it is also possible to determine the awareness mechanisms that should be used. In the screenshot of the Blueototh Starter shown above, it can be seen that platform proxy components are shown as subcomponents of the platforms component. VirtualBox or Android emulator. Awareness Architecture Awareness architecture The awareness component is functionally split into a management and a discovery part.
Using message discovery is especially beneficial in asymmetric network settings, in which one partner can find the other but not vice versa.

This will start the platform with or without the awareness component. The concept of proxy components makes handling interactions with remote components rather simple. This delay is propagated down to all awareness mechanisms at startup. It uses the default port ”. This can be done by using:. Currently the following discovery mechanisms are available base package jadex.
The user interface also visualizes the state of the remote components. The local discovery uses a bluetoooth mechanism to detect platforms running on the same host.
