ENABLING DEEP SLEEP AND POWER SAVING THROUGH L1 SIGNALING ON STACK INTERFACE

摘要

Embodiments generally provide techniques for waking up a plurality of network devices from a power saving mode via layer 1 (L1) signaling. Embodiments include entering a power saving mode at a first network device, wherein logic for processing layer 2 and higher data is inactive during the power saving mode and receiving, while the first network device is in the power saving mode, a L1 bit stream from a second network device connected to the first network device. Additionally, embodiments include, upon determining that a predefined code is present within the received L1 bit stream, exiting the power saving mode at the first network device and transmitting a second L1 bit stream containing the predefined code to a third network device.

1. A method, comprising:
entering a power saving mode at a first network device, wherein logic for processing layer 2 and higher data is inactive during the power saving mode; while the first network device is in the power saving mode, receiving a layer 1 (L1) bit stream from a second network device of a plurality of network devices connected to the first network device; upon determining that a predefined code is present within the received L1 bit stream:
exiting the power saving mode at the first network device; and thentransmitting, from the first network device, a second L1 bit stream containing the predefined code to a third network device of the plurality of network devices.
