ADDTS es la abreviatura de ADD Traffic Stream y es un marco de gestión que pertenece a la categoría Qos.
Traffic Stream es un flujo de transporte. Específicamente, ¿cuáles son los atributos del flujo? Requisitos de velocidad, ancho de banda y retardo, por lo que refleja las necesidades de Qos.
Si STA desea transmitir un TS específico, debe solicitarlo al AP a través del mecanismo TSPEC de antemano. Por ejemplo, si un dispositivo WLAN desea utilizar AC de voz (VO), primero debe solicitarlo .
Para AC Best (BE) y Background (BK), no se requiere el mecanismo TSPEC .
El elemento TSPEC existe en marcos de asociación y marcos de acción ADDTS .
Por ejemplo, cuando queremos utilizar el equipo WLAN de Cisco (WLC) para llamadas de voz, es posible que el equipo no esté configurado en el perfil Qos platino. Este es el nivel de Qos correspondiente a la voz.
Los tres restantes son Gold Qos (Gold / Video), Silver Qos (Silver / Best Effort) y Bronze Qos (Bronze / Background).
En la interfaz CLI de WLC, utilice el comando 'debug cac all enable' para depurar, y el siguiente resultado debería aparecer.
Aquí se muestra que el AP ha recibido la solicitud ADD del VO TS (tsid = 6 / up = 6 / tid = 6 / ac = 2) del STA en la dirección 1a. Pero lo rechazó.
