Title: Method and allocating switching-oriented resources in a communication system operating in the asynchronous transfer mode
Inventor: HUENLICH KLAUS
IPC: H04L12/54
Filed: 1993-09-27
Abstract: The allocation of the switching-oriented resources of a communication system (KS) operating in the asynchronous transfer mode is controlled for connections wherein cells (Z) communicated by a communication terminal equipment (KE) connected to the communication system (KS) are to be switched without cell losses.      Logon information and scope of resources information (ai, ri) communicated within the framework of the call signaling are thereby entered in call-associated fashion into an immanent routing table (LT) of the communication system. Given reception of a first cell (Z) to be communicated free of losses, this and the further cells (Z) are switched with the assistance of the logged on switching-oriented resources (VR) in so far as no resources availability information (rvi) dependent on the traffic load of the communication system (KS) is entered into the routing table (LT).      Given a successful switching, resources use information (rvi) is inserted into the routing table (LT), as a result whereof the switching-oriented resources (VR) are exclusively allocated to the call for the switching of the cells (Z) to be communicated free of cell losses.
