DEEP SLEEP MODE MANAGEMENT FOR A NETWORK SWITCH

摘要

A switch (100) connected to a network is configured to have one or more components that can be placed in a deep sleep mode. The switch (100) includes a management circuit (150) that is configured to wake up the components in deep sleep mode. The management circuit (150) includes a port (151) that receives packets and a wake-up circuit (152) that determines whether a packet received via the port (151) is a magic packet including a unique ID for the port (151) or the switch (100). If the packet is the magic packet including the unique ID for the port (151) or the switch (100), the wake-up circuit (151) is configured to send a wake-up signal to components in the switch (100) to wake up from the deep sleep mode.
