• Point-to-point, ad-hoc, connection model • Connections are set up on request by the application code, i.e., application controls the topology • Various protocols can be plugged in, currently Bluetooth, TCP and HTTP are supported • Connection status is monitored, application is notified • Connections are re-established automatically if broken
