The present invention describes a protocol with which it is possible to establish a connection suitable for voice communication in a network such as Internet. In a first step, a PATH message is transmitted from an initiator (1) to a called station (2). In a second step, an RESV message is transmitted from the called station (2) back to the initiator (1), along the same route (23) followed by the PATH message. If either the initiator (1), or the called station (2), or both, contain information in the PATH message and/or the RESV message that indicates payment willingness, each router (22) along the route (23) will reserve a part of its capacity for a direct connection.
On décrit un protocole à l'aide duquel il est possible d'établir une connexion adaptée à la communication vocale dans un réseau tel qu'Internet. Dans une première étape, un message PATH est envoyée d'un demandeur (1) à une station appelée (2). Dans une deuxième étape, un message RESV suivi d'un message PATH est renvoyé par la station appelée (2) au demandeur (1) par le même chemin (23). Si le demandeur (1) et/ou la station appelée (2) insèrent dans le message PATH et/ou le message RESV des informations qui indiquent la volonté de payer, chaque routeur (22) situé sur le chemin (23) réserve alors une partie de sa capacité pour une connexion directe.
