| Approche de signalisation DiffServ |
La Recommandation UIT-T H.248.81 contient des lignes directrices relatives à l'utilisation de l'indicateur d'appel et de l'indicateur de priorité du plan international de priorité en période de crise (IEPS) dans les profils UIT-T H.248 pour les systèmes UIT-T H.323 et NGN. D'autres organisations de normalisation pourront utiliser ces lignes directrices lorsqu'elles définiront leurs profils en vue de la prise en charge de services prioritaires, par exemple le service de télécommunications d'urgence (ETS) ou le service prioritaire multimédia (MPS).
L'Amendement 1 à la Recommandation UIT-T H.248.81 (2011/05) contient des adjonctions et des corrections à la Recommandation et un nouvel Appendice II relatif à l'utilisation des notifications ECN dans le contexte du trafic ETS.
L'Amendement 2 à la Recommandation UIT-T H.248.81 (2011/05) contient des adjonctions à la Recommandation pour assurer le marquage des appels prioritaires en utilisant le paquetage de signalisation DiffServ défini dans la Recommandation UIT-T H.248.52. |
