Abstract

Systems and methods that facilitate remote wake up are described that provide for efficient and transparent wake up of target hosts by remote hosts. In various embodiments, a separate address can be used by a target host for wake up network traffic, which is different from a regular address associated with a target host for normal network communications. In addition, the disclosed subject matter facilitates controlling wake up operations according to trust, identity, and/or a wake up policy.

Claims

1. A method facilitating remote wake up of a target host, the method comprising:

acquiring, by the target host, a separate address to receive wake up network traffic;

communicating the separate address to a computer system prior to the target host entering a sleep mode; and

receiving, by the target host, wake up network traffic associated with the separate address.

2. The method of claim 1, further comprising restoring, by the target host, from the sleep mode to resume network communications using an address distinct from the separate address.

3. The method of claim 2, further comprising communicating the address distinct from the separate address to the computer system.

4. The method of claim 1, further comprising communicating a wake up policy to the computer system, the wake up policy includes restrictions on remote wake up operations based at least in part on a time-based distinction, a network information based distinction, an application-based distinction, a user identity-based distinction, a host identity-based distinction, an event-based distinction, a state-based distinction, or a geographic related distinction.

5. The method of claim 1, further comprising establishing a secure communication channel with the computer system for securely communicating at least one of the separate address or the wake up policy.

6. The method of claim 1, the wake up network traffic includes at least one of an address resolution protocol request associated with the separate address or an internet protocol version six neighbor discovery request associated with the separate address.

7. The method of claim 1, the computer system is a remote host.

8. The method of claim 7, further comprising using, by the target host, a new separate address to receive subsequent wake up network traffic to prevent the remote host from performing subsequent remote wake up operations.

9. The method of claim 7, the communicating includes communicating the separate address to the remote host based in part on a determination of whether the remote host can be trusted.

10. The method of claim 9, the determination of whether the remote host can be trusted is performed in part by an authentication component of a third host.

11. The method of claim 1, the computer system is a resolution server.

12. The method of claim 11, the receiving includes receiving wake up network traffic associated with the separate address from the resolution server based at least in part on a determination of whether a host requesting resolution of the target host can be trusted or allowed by the wake up policy.

13. The method of claim 12, the determination of whether the host requesting resolution of the target host can be trusted is performed in part by an authentication component of the resolution server.

14. A system facilitating remote wake up, the system comprising a target host, the target host further comprising:

a storage component for storing data and instructions for placing the target host in a sleep mode, setting one or more wake up traffic patterns, and waking the target host upon receiving one of the one or more wake up traffic patterns; and

a communication component configured to receive network traffic associated with a first address when the target host is not in the sleep mode, to receive and recognize network traffic associated with a second address as one of the one or more wake up traffic patterns when the target host is in the sleep mode, and to signal the target host to resume from the sleep mode based in part on the recognition of one of the one or more wake up traffic patterns.

15. The system of claim 14, the communication component is further configured to send at least one of a wake up policy or the second address to one or more of a remote host or a resolution server, the wake up policy restricts remote wake up of target host based at least in part on a time-based distinction, a network information based distinction, an application-based distinction, a user identity-based distinction, a host identity-based distinction, an event-based distinction, a state-based distinction, or a geographic related distinction.

16. The system of claim 14, the target host further comprising an authentication component configured to authorize remote wake up of the target host by the remote host.

17. The system of claim 14, the one or more wake up traffic patterns includes at least one of an address resolution protocol request associated with the second address or an internet protocol version six neighbor discovery request associated with the second address.

18. A system facilitating remote wake up, the system comprising a resolution server, the resolution server further comprising:

an authentication component configured to determine whether a remote host is authorized to remotely wake up a target host; and

a communication component configured to receive a wake up address associated with the target host, the wake up address is distinct from a normal address of the target host, to transmit network traffic to the wake up address associated with the target host based in part on whether the remote host is authorized to remotely wake up the target host, and to transmit the normal address of the target host to the remote host based on a resolution protocol.

19. The system of claim 18, the communication component is further configured to receive wake up policy information concerning the target host, the wake up policy information facilitates restricting remote wake up of the target host based at least in part on a time-based distinction, a network information based distinction, an application-based distinction, a user identity-based distinction, a host identity-based distinction, an event-based distinction, a state-based distinction, or a geographic related distinction.

20. The system of claim 18, further comprising a cryptographic component configured to establish a secure channel for securely receiving at least one of the wake up address or the wake up policy information concerning the target host.
