Title (EN) METHOD FOR PROVIDING IP TELEPHONY WITH QoS USING END-TO-END RSVP SIGNALING
(FR) PROCEDE PERMETTANT DE FOURNIR UN SERVICE TELEPHONIQUE A PROTOCOLE INTERNET AVEC UNE QUALITE DE SERVICE UTILISANT UNE SIGNALISATION DE PROTOCOLE RSVP POINT A POINT
Abstract: front page image
(EN)This invention relates to the field of Internet Protocol communications. more particularly, this invention is a method for setting up, authorizing, maintaining, and terminating an IP telephony sesson with quality of service across the Internet by combining session initiation protocol, resource reservation protocol, common open policy service, and open settlement protocol. The method of this invention allows an IP telephony session to benefit from all these protocols. With reference to Fig. 1, an embodiment of this invention involves an SIP client (115, 130, 135, 136) that uses SIP and RSVP; SIP proxy servers (150, 151) that use SIP and COPS; policy servers (140, 141, 142) that use COPS and OSP; a clearinghouse server (180) that uses OSP; and several routers that use RSVP and COPS (e.g., 160, 161, 170).
(FR)L'invention concerne un procédé dans lequel on utilise conjointement des protocoles séparés, tels que le protocole SIP (session initiation protocol), le protocole RSVP (resource reservation protocol), le service COPS (common open policy service), et le protocole OSP (open settlement protocol) pour établir, assurer, et interrompre des communications Internet possédant une qualité de service acceptable. Ce procédé est mis en oeuvre par établissement dynamique d'une politique RSVP en fonction de demandes téléphoniques SIP, de façon à fournir des communications sur l'Internet avec une qualité de service.
