The idea is to offer a Quality of Service (QoS) reservation through a SOAP (Simple Object Access Protocol) web server. Up to now the reservation service must be involved by the IP end parties and often designed for spe-cific application (VoIP – Voice over Internet Protocol). The QoS service invocation is complicated and not easy to use. One application in the new process (a client/server application, anywhere in IP network) sends a SOAP request of QoS reservation to the QoS web server. 1. The request contains all information needed by the web sever to realize the reservation: IP and TCP/UDP (Transmission Control Protocol / User Datagram Protocol) ports of A and B parties, traf-fic protocol, estimated duration of reservation, account number or prepaid vouchers. 2. The web server checks that the request is valid and authorized and sends the request to the RCA (Resource Control Agent). 3. The RCA checks that the request could be accepted (the network resources are available) and sends the acceptance response to the QoS web server. 4. The QoS web server responds to the application that the reservation request is accepted. 5. The application acknowledges the response to the QoS web server (confirmation of the reserva-tion). 6. The web server confirms the reservation to the RCA. If during the establishment of the reservation, the reservation time duration is not predictable, a ses-sion is created and a similar mechanism of the establishment of QoS tunnel is used to finish the QoS tunnel. The QoS web server generates bills according to prepayment and tickets according to subscription to invoice the service.
