multiplexacin estadstica.

Beneficios de Docsis 2.0


Adquisicin del canal. Obtencin de los parmetros de upstream. Ajuste fino de los parmetros (ranging) Respuesta del CMTS Asignacin de IP Registro

Etapas de registro de un CM.

Introduccin a DOCSISDiagrama de registro de un CM.

Introduccin a DOCSISEtapas de Registro - Adquisicin del Canal.

El mdem barre toda la banda buscando un canal de downstream

Cuando encuentra una seal QAM se detiene e identifica si transporta informacin mpeg2

Dentro de los paquetes mpeg busca el PID para ver si existen datos Docsis.

Cuando el mdem encuentra una seal mpeg que transporta informacin Docsis la adquisicin del canal se considera exitosa.

La informacin de MAC se pasa a la siguiente capa

Introduccin a DOCSISEtapas de Registro - Obtencin Parmetros Upstream

El mdem espera recibir Tres mensajes MAC que el CMTS enva repetidamente en todos los canales de downstream.

El primer mensaje es el Tiempo de sincronizacin (SYNC) que provee una referencia de tiempo comn a todos los mdems.

El segundo mensaje es un Descriptor del canal de upstream (UCD) donde se especifica frecuencia de transmisin y modulacin .

El ultimo mensaje es un Mapa de asignacin de ancho de banda (MAP) que describe cuando puede transmitir y por cuanto tiempo.

Introduccin a DOCSISEtapas de Registro - Ranging

El procedimiento de ranging involucra un ajuste fino de los parmetros de transmisin : - Ajuste fino de la Referencia de tiempo.- Ajuste fino de la Frecuencia de transmisin. - Ajuste fino del Nivel de transmisin (potencia).

Como cada mdem esta a una distancia diferente del CMTS estos ajustes resultan diferentes para cada equipo

Introduccin a DOCSISEtapas de Registro - Ranging

El mdem transmite un mensaje al CMTS durante una ventana de mantenimiento definida en el MAP.

El mdem transmite su pedido de ajuste de ranging basado en su interpretacin del SYNC y del MAP

EL CMTS debe responder al cable mdem. Si despus de un tiempo el cable mdem no recibe respuesta

pueden suceder dos cosas: - Se produjo una colisin con otro cable mdem. - El nivel de transmisin era muy bajo.

Si el mdem no recibe respuesta a su pedido, deja pasar un numero aleatorio de ventanas de mantenimiento y vuelve a transmitir con mayor nivel.

Introduccin a DOCSISEtapas de Registro Respuesta del CMTS

Cuando el CMTS recibe el pedido del mdem detecta : - Desplazamiento dentro de la ventana de mantenimiento.- Frecuencia de transmisin del mdem. - Nivel de seal recibida en el puerto de upstream .

Basado en esta informacin el CMTS determina las correcciones y se las enva al cable mdem.

Una vez que el CMTS recibe el pedido de mantenimiento el resto del proceso de ranging se realiza utilizando mini-slots de tiempo sin que exista riesgo de colisiones.

Al recibir la respuesta del CMTS el mdem ajusta sus parmetros y emite un segundo pedido de ranging.

Introduccin a DOCSISEtapas de Registro Respuesta del CMTS

El dialogo entre el CMTS y el mdem continua hasta que el CMTS queda satisfecho con los parmetros que utiliza el mdem : - Sincronismo con errores inferiores a 1 microseg.- Frecuencia de transmisin dentro de +/- 10 Hz.- Nivel de transmisin dentro de +/- 0.5 dB

Este ciclo de ajuste se realiza cuando el mdem se conecta por primera vez a la red y se repite segn ciclos de mantenimiento pre-establecidos en el CMTS para asegurar una comunicacin continua y confiable.

Introduccin a DOCSISEtapas de Registro Ajuste de SYNC

El ajuste de SYNC requiere compensar los retrasos por : - Latencia. - Retardos en la propagacin.- Tiempos de procesamiento en CMTS y mdem.

Un desplazamiento de tiempo precalculado fuerza al mdem a transmitir antes del mini-slot asignado.

Todas las transmisiones basadas en ciclos Request-Grant

Cuando un mdem necesita transmitir pide se le asigne ancho de banda (request) utilizando una ventana definida en el MAP y el CMTS le asigna una ventana de transmisin (grant)

Introduccin a DOCSISEtapas de Registro Asignacin de IP

El mdem requiere establecer conectividad IP El mdem obtiene una IP a travs del protocolo DHCP

(Dynamic Host Configuration Protocol) El DHCP corre entre el Mdem y un Servidor de DHCP

administrado por el MSO u otro prestador. Mientras el Mdem esta activo mantiene su IP pero despus de

un cierto tiempo de inactividad el servidor de DHCP libera esa IP y la misma puede ser tomada por otro equipo.

Con esta asignacin dinmica se optimiza el uso del rango de direcciones IP.

Introduccin a DOCSISEtapas de Registro Obtencin de ToD

Una vez que el Mdem obtiene una IP solicita el ToD al server (Time of Day) para sincronizar su fecha y hora.

El SYNC y el TOD son dos cosas diferentes. El SYNC es un contador de 32 bits que coloca marcas de

tiempo para el correcto funcionamiento de la capa MAC (evitar colisiones).

El ToD es informacin de fecha y hora actuales que el mdem utiliza con ciertos mensajes y archivos log para identificar cuando se generaron (timestamp) o sincronizar sus mensajes cuando se utiliza BPI.

Introduccin a DOCSISEtapas de Registro Registro

El proceso de registro comienza cuando el mdem baja el archivo de configuracin

La direccin IP del servidor que contiene el nombre del archivo de configuracin y el nombre del archivo estn en la respuesta del servidor de DHCP al Mdem.

Para bajar el archivo de configuracin utiliza protocolo TFTP (Trivial File Transfer Protocol)

El archivo de configuracin lleva informacin de : - Anchos de banda de Upstream y Downstream.- Flujos de servicios asignados al cable mdem, BPI, etc.

6. Rango de frecuencias permitidas con un ancho de canal de 6MHz

7. El comando no cable downstream rf-shutdown activa el modulador integrado de la tarjeta MC520 para ese downstream en particular ya que de no activarse genera frecuencia intermedia y se requiere de un modulador externo.

4. Para DOCSIS 2.0 la frecuencia es del tipo narrowcast lo cual indica que no es posible asignar un grupo de frecuencias solo una unica freceuncia.

5. Para DOCSIS 2.0 es necesario configurar atdma y que los cable mdems que se encuentren en ese nodo sean DOCSIS 2.0

6. El ancho del canal puede ser de 3.2 o 6.4 MHz aunque lo ptimo es utilizar 6.4 MHz para brindar un ancho de banda mayor

7. Asignacin del profile de modulacin adecuado para DOCSIS 2.0.
