Patent ID: 7327677

Claim:
A method for establishing a packet-oriented connection of predetermined performance using a network transmission device and a transmission path, comprising: managing a transmission-oriented set of resources on the transmission path by a resource manager, reading data packet address information from data packets that have been transmitted or are to be transmitted over the transmission path, the data packets being independent from the connection to be established, the address information identifying the origin and destination of the data packets and being read by the network transmission device; transmitting the address information from the network transmission device to the resource manager, transmitting a resource request to the recourse manager in order to establish the connection, the resource request having connection information identifying the origin and destination of the connection, the address information being transmitted before the resource request, using the connection information and the data packet address information to determine whether the origin and destination of the connection match the origin and destination of the data packets, and if the origin and destination of the connection match the origin and destination of the data packets, considering available resources on the transmission path in further evaluating establishment of the connection such that a positive match causes the available resources to be considered.
