Abstract

Esta solicitud proporciona un método de aislamiento y recuperación y un dispositivo de red para el caso en que uno o más aparatos de capa física PHYs en un grupo de Ethernet flexible, grupo de FlexE tengan fallo. El método incluye: Si un dispositivo de red determina que un primer bloque de sobrecarga que corresponde a cada PHY actual disponible se almacena en una memoria correspondiente, el dispositivo de red determina que un grupo de FlexE cumple una condición de alineación de PHY y comienza a leer simultáneamente los datos almacenados en caché de todas las memorias. Por lo tanto, no es necesario insertar bloques de código de LF de fallo local en todos los clientes (clients) y no es necesario volver a crear un grupo. Esto reduce de manera efectiva el impacto de un PHY con fallo en un servicio de cliente realizado por un PHY normal. Además, se establece un mecanismo de retardo de lectura de memoria para absorber eficazmente un cambio de retardo causado por el PHY con fallo, y no es necesario realizar una operación de alineación de PHY nuevamente, implementando así la recuperación ante fallos sin pérdidas del PHY.
