                                | Protocolo de control de pasarela: Paquetes de encaminador IP |  
                                | La Recomendación UIT-T H.248.64 trata de las pasarelas de medios UIT-T H.248 con modelos de conexión que sólo utilizan flujos/terminaciones UIT-T H.248 IP. Se describen los diversos modos del reenvío de paquetes IP (en el trayecto portador UIT-T H.248). En esta Recomendación se define además un lote UIT-T H.248 para la discriminación de tales modos y elementos de protocolo para el denominado método de reenvío por encaminador IP. Otros lotes UIT-T H.248 ofrecen capacidades para el reenvío de paquetes mejorado por el servicio con respecto al soporte de la traducción de dirección de red adicional.En esta revisión se aclara el proceso de entrega de un paquete entrante al contexto/terminación/flujo UIT-T H.248 para conservar la coherencia con la Recomendación UIT-T H.248.79. |  |
