Wake-on-LAN between optical link partners

摘要

Embodiments described herein achieve Wake-on-LAN to allow optical modules the ability to wake up link partners instantaneously when there is data to be transmitted or received. As such, Wake-on-LAN features are provided for a side-band handshaking protocol and channel that is independent from the normal data traffic path.

1. A method comprising:
determining that an optical module is capable of entering a power saving mode based at least in part on the value of a power saving capable register, wherein the power saving capable register is stored in a memory associated with a transceiver, wherein the memory further stores a partner device power saving capable register; initiating a power saving handshake; confirming the power saving handshake; adjusting the optical module to a power saving mode; and sending an idle pattern, wherein the idle pattern serves to end the established power saving mode.
