A system and method for wireless waking computing devices over a computer network is provided. A signal is broadcast over the network that includes one or more device specific wake-up data sequences. Each device specific wake-up data sequence includes multiple iterations of the hardware address of the wireless network card associated with that device. While in a reduced power or “sleep mode”, the wireless network card monitors wireless channels for packets containing a wake-up data sequence. If a wake-up data sequence is received, the sequence is matched against the hardware address information for that network card. If a match is determined, the network card sends a signal to the computing device causing full system power to be restored. A signal is sent to the network confirming that the device has been successfully woken from the sleep mode.

A system and method for providing services such as Wake-on-LAN and PXE Boot services to a multi-subnet network system which includes router and/or firewalls between different subnets. This is accomplished by using a peer computer to provide the service when performing such service is required to be transmitted across the router and/or firewall. That is, the system determines whether the service is required to go across the router and/or firewall, and, if so, to identify a computer (a peer computer) which is located on the appropriate subnet, then deliver the service to that peer computer (if necessary) and have that peer computer perform the selected service, such as Wake-on-LAN.

Systems and arrangements for remotely selecting a bootable image via a WOL packet for a wake-on-LAN (WOL) capable computer are contemplated. Server-side embodiments include hardware and/or software for determining a client to be managed, determining whether the client is active on the network, and transmitting a WOL packet having a vector, or operating system partition identification (OSPID), to describe a bootable image accessible by the WOL capable computer. Some embodiments may include an OSPID that points to a secure bootable image such as a bootable image on a hard drive, a compact disk (CD) connected to the computer, or other local resource. Client-side embodiments may receive the WOL packet at, for instance, a network interface card (NIC), recognize that the WOL packet includes an OSPID that describes the bootable image to boot, and implement an alternative boot sequence to boot from that bootable image.

Systems, methods, and media for providing remote wake-up and management of systems in a network are disclosed. More particularly, hardware and/or software for a server to receive feedback from a client as to the status of its wake-on-LAN functionality is disclosed. Embodiments include hardware and/or software for determining a client to be managed, determining whether the client is active on the network, transmitting a first network packet comprising a wake-on-LAN packet, and receiving a return wake-on-LAN packet, which comprises an indication of the address of the client and an indication of the status of the wake-on-LAN functionality of the client. Embodiments may also include transmitting a command to start a management session on the client.

A system and method for autonomic extensions to wake on LAN are presented. An access point detects wake on LAN (WOL) requests that are targeted for unassociated clients. When the access point detects a WOL request for an unassociated client, the access point stores the WOL request in a table for a predefined amount of time. A client queries the access point periodically to see if the access point is storing a WOL request which is targeted for the client. When the access point receives the query, the access point compares the client's identifier, such as its MAC address, with targeted client identifiers corresponding to pending WOL requests. When the access point detects a match, the access point sends the WOL request to the client for the client to process.

Methods, systems, and media are disclosed for managing a remote client of a computer system. One example embodiment includes transmitting a modified wake-on LAN (“WOL”) packet to a network receive buffer on the remote client, wherein the modified WOL packet comprises additional data, such as executable code or functions. Further, the example embodiment includes retrieving, by BIOS associated with the remote client, of the modified WOL packet from the network receive buffer, storing, by the BIOS, storing of the additional data in memory associated with the network receive buffer, and retrieving, by BIOS associated with the remote client, of the additional data from the memory. Further still, the example embodiment includes processing of the additional data, which may occur by an application stored on the PARTIES partition, wherein the parsed, additional data is interpreted and executed by the application.

A system, method, and program product is provided that deploys an operating system. The first computer system sends a Wake-on-LAN instruction and boots each of the second computer systems. The second computer system identifies a set of third computer identifiers that corresponds to each of the selected second computer systems. The second computer systems send the Wake-on-LAN instruction to each of the third computer systems, and the third computer systems are booted over the computer network from the second computer systems. A control file lists the first computer system as a “server” of the second computer systems and lists the second computer systems as “servers” of the third computer systems. The control file is transmitted from a server to each of the server's clients. When a client is booted, it checks the control file to determine if the client is also a server to other computer systems.

To improve Wake-on-LAN (WOL) functionality of a device, a Media Access Control (MAC) address filtering function may be implemented in the device's Ethernet physical layer (ePHY) block. When the ePHY detects a WOL frame, the MAC filtering function in the ePHY may perform address comparison between the MAC address associated with the device, and the MAC address contained in the WOL frame. Performing the MAC address comparison within the ePHY allows the main system components, such as the main SOC and other components to remain in standby mode (or sleep mode) until a MAC address match has been determined. Therefore, the main system components do not need to be rebooted every time the device receives a WOL frame, only when there is a match between the MAC address of the system and the MAC address contained in the detected WOL packet.

A single integrated circuit includes logic that supports 10BASE-T, 100BASE-T and 1000BASE-T transceiver functionality. The invention implements power management techniques by placing unused functionality in sleep mode. When the functionality is required later, then that functionality may be awakened again and used as required for the particular situation. A processor is able to interact with the media access controller (MAC), and the MAC then communicates with the physical layer (PHY). The invention is adaptable to various devices that are capable to operating using 10BASE-T, 100BASE-T and 1000BASE-T, even those the PHY of these devices may be somewhat different.

A system and method for remote power control across multiple distinct nodes of a logically coherent data processing system where each node has the design of a traditional standalone SMP server. The system is partitioned into two or more static partitions. Remote power control for the partition is achieved using a modified wake-on-LAN implementation in which magic packet filters on each NIC in the partition are modified to enable remote, partition-wide restart by a magic packet that is recognized by or common to all of the nodes. In one embodiment the wake-on-LAN filters of each NIC in the partition recognize and respond to magic packets addressed to any of the NIC's in the partition. In another embodiment, the wake-on-LAN filters of each NIC in the partition are modified to respond to a universal magic packet.

A method and system for managing peripheral connection wakeup signaling in a processing system supporting multiple virtual machines provides a mechanism by which ownership of a peripheral having system wakeup capability is transferred between virtual machines. The power management event signal is connected to a service processor input that in turn signals a hypervisor to direct the wakeup activity to a particular logical partition in which the virtual machine was last executing. The hypervisor can then determine whether or not to wake up the entire system, or portions thereof and can direct the power management event to the appropriate virtual machine. In particular the peripheral may be an Ethernet adapter supporting Wake-On-LAN capability. State initialization, which is typically ensured by system power cycling is provided instead by controlling power to the standby power source or in some instances by forcing an indication of a disconnect/reconnect of the wakeup signaling connection.

In a computer network including a plurality of interconnected computers, one of the computers being a sleeping computer in a power down state, the sleeping computer listening for a packet associated with the sleeping computer, a method of waking the sleeping computer from the computer network. An incoming packet of data is transmitted from an administration system in the network to the sleeping computer. When the sleeping computer detects the incoming packet, it determines if the incoming packet contains a data sequence associated with the sleeping computer. If the incoming packet matches the particular data sequence associated with the sleeping computer, the sleeping computer transmits a reply message to the administration system. Upon receiving the reply, the administration system modifies the reply message in a predetermined manner and transmits the modified reply to the sleeping computer. If the sleeping computer determines the reply message was modified in the predetermined manner, then a signal is issued to wake the sleeping computer. Otherwise, the incoming packet is discarded and the sleeping computer is not awakened.

Methods and systems are disclosed for a Wake On LAN (WOL) computer system startup process that receives WOL instructions and control information for modifying the computer system startup process. The control information may be, for example, a password, or instructions to enter the system by bypassing a password. The password can be a system password or a hard drive password. The control information may be, for example, an instruction to boot up from another device, such as a network server. The control information may also be an instruction to disable Alert Standard Format (ASF) reporting. Thus, the boot up procedure can be reconfigured to a modified boot up sequence based upon control information provided as part of the WOL process.
