Method for implementing wake events via peer-to-peer connections

Disclosed is a method for implementing wake events via peer-to-peer connections. Benefits include improved functionality.

Background

              The power supplied to the 1394(a) system is derived from 12V and by definition does not support wake events as this power rail is not present during advanced power saving sleep states.  Currently, there are no desktop systems available that provide a 12-volt stand-by rail to the 1394(a) ports, resulting in a loss of management features for this particular I/O interface.

Description

              The disclosed method is a configuration where two computers are networked via a 1394(a) peer-to-peer connection (see Figure 1). Stand-by power is provided to the ports via on-board logic where suspend power-wells are maintained on the platform. A remotely attached system may execute a wake sequence via the bus interface to gain access to software/hardware within the targeted system.

              The Advanced Configuration and Power Interface (ACPI) wake events generated across the bus interface are not defined because the primary usage of these systems is for asynchronous bus transfers, such as hard disk drive and compact disk (CD-R/W).

              Secondary functions include peer-to-peer networking.

Advantages

              Some implementations of the disclosed structure and method provide one or more of the following advantages:
