METHOD FOR SETTING UP A TWO-DIRECTIONAL CONNECTION

The method involves receiving a connection establishing message at an intermediate node (B) on a connection path, and evaluating communication resources of the intermediate node for downward and upward data flows. Content of the message is updated and transmitted to a terminator node (C). The message is received at the terminator node. A reservation message including traffic parameters or descriptors (31, 32) is sent to an initiator node (A). The resources are reserved for the downward data flow according to the descriptors along the connection path. An independent claim is also included for a communication device for a communication network, comprising communication resources.
