Embodiment Construction

[0037] Exemplary, non-limiting embodiments of the present application will now be described with reference to the aforementioned drawings.

[0038] figure 1A computer network 10 is illustrated with a network switch 12 acting as a WOL proxy. The WOL proxy 12 is also known as a WOL proxy server or a WOL proxy computing server. Specifically, the computer network 10 includes a first virtual LAN (VLAN, virtual local area network or first subnet) 14, a network switch 12, and a second virtual LAN 16 (ie, a second subnet) that are sequentially connected together via a network switch 12. .

[0039] The first VLAN 14 includes a management server 18 and the management server 18 is connected to the network switch 12 via a first Ethernet port 20 of the network switch 12 . The second VLAN 16 has a sleep server 22 and the sleep server 22 is connected to the network switch 12 via a second Ethernet port 24 of the network switch 12 .

[0040] In addition to the first Ethernet port 20 and th...

Abstract

The embodiment of the invention relates to a network switch for executing LAN wakeup. The network switch comprises a processor and a computer port, wherein the processor can be operated to determine the mapping relationship among a media access control (MAC) address, an Internet protocol (IP) address and a subnet address; the computer port is coupled to the processor; the computer port can be operated for receiving an LAN wakeup packet from a first calculation device in a first subnet to wake a second calculation device in a second subnet up from a sleep mode; and the processor is configured to receive the LAN wakeup packet from the computer port, determine the second calculation device to be located in the second subnet according to the mapping relationship and transmit the LAN wakeup packet to the second subnet to wake the second calculation device up from the sleep mode.

Description

technical field [0001] This patent application relates to network switches for implementing Wake On LAN (WOL). This patent application also relates to methods of installing, configuring and using network switches. Background technique [0002] Organizations often seek to reduce the electrical power consumption of network equipment for various reasons, such as to reduce costs. Network devices can simply be referred to as nodes. One way to reduce electrical power consumption is by keeping idle network devices in their power saving states (i.e. lower power states), such as in modern standby, sleep (S1, S2, S3), hibernation ( S4) and soft shutdown state (S5). However, in order to accommodate various business needs, these idle network devices need to be fully powered up for access whenever needed. For example, a traveling employee may need to remotely access his office computer within the company's network from overseas, even during non-normal business hours, to handle urgent...
