Abstract

A micro-staging device has a wireless interface module for detecting a first data request that indicates a presence of a user and an application processor that establishes a network connection to a remote data center. The micro-staging device further allocates a portion of storage in a cache memory storage device for storing pre-fetched workflow data objects associated with the detected user.

Claims

1. A micro-staging device comprising:

a wireless interface module in a mesh WLAN network and operatively coupled to a wireless access point in a physical wireless traffic area for detecting a first data request indicating a presence of a user information handling system in the physical wireless traffic area, wherein the micro-staging device serves the physical wireless traffic area including one or more wireless access points and the micro-staging device forming a portion of the mesh WLAN network associated with the micro-staging device and wireless range associated with that one or more wireless access points and the micro-staging device in the portion of the mesh WLAN network associated with the micro-staging device; and

an application processor for establishing a network connection to a remote data center via a backhaul connection with the wireless access point and for pre-fetching workflow data from the remote data center based on a contextual policy;

the application processor further allocating a portion of storage in a cache memory storage device for storing pre-fetched workflow data associated with the user information handling system; and

the wireless interface module further adapted to transmit pre-fetched workflow data from the cache memory storage device at the micro-staging device in response to receiving a second data request from the user information handling system to reduce the burden of communications on the user information handling system to retrieve the pre-fetched workflow data from within the mesh WLAN network;

wherein the workflow data pre-fetched according to the contextual policy are received from the remote data center based on identification of a project associated with the first data request.

2. The micro-staging device of claim 1, wherein the pre-fetched workflow data pre-fetched according to the contextual policy are received from the remote data center further based on an identification of a presence of another team member information handling system associated with the project in the physical wireless traffic area.

3. The micro-staging device of claim 1, wherein the application processor is further adapted to:

establish a connection with a virtual machine pre-fetch application at the remote data center for executing the contextual policy to select pre-fetched workflow data.

4. The micro-staging device of claim 1, wherein the application processor is further adapted to:

detect that the user information handling system is no longer present in the physical wireless traffic area;

eject the stored pre-fetched workflow data; and

de-allocate the portion of storage.

5. The micro-staging device of claim 1, wherein the application processor is further adapted to:

store changed workflow data received from the user information handling system in the allocated storage and forward the changed work flow data to the remote data center for back-up upon receipt from the user information handling system.

6. The micro-staging device of claim 1, wherein the pre-fetched workflow data pre-fetched according to the contextual policy are received from the remote data center further based on identification of a calendared meeting for the project.

7. The micro-staging device of claim 1, wherein the physical wireless traffic area in the mesh WLAN network serves a physical area of up to two wireless link stages from the micro-staging device to the user information handling system via an intermediary wireless access point and its wireless range.

8. A method comprising:

receiving at a micro-staging device in a mesh WLAN network and operatively coupled to a wireless access point in a physical wireless traffic area an indication of a presence of a user information handling system detected in the physical wireless traffic area, wherein the micro-staging device serves the physical wireless traffic area which includes one or more wireless access points and the micro-staging device forming a portion of the mesh WLAN network associated with the micro-staging device and wireless range associated with that one or more wireless access points and the micro-staging device in the portion of the mesh WLAN network associated with the micro-staging device;

sending a command to a virtual machine pre-fetch application to provide pre-fetched workflow data according to a contextual policy at a remote data center via a backhaul network connection with the wireless access point;

allocating a portion of storage at the micro-staging device for storing pre-fetched workflow data associated with the user information handling system;

receiving pre-fetched workflow data from the remote data center;

detecting a data request from the user information handling system; and

transmitting responsive pre-fetched workflow data from the micro-staging device to the user information handling system to reduce the burden of communications on the user information handling system to retrieve the pre-fetched workflow data from within the mesh WLAN network;

wherein the contextual policy determines workflow data to be pre-fetched by the virtual machine pre-fetch application and includes a user-defined instruction reflecting a policy to retrieve workflow data associated with an identified application.

9. The method of claim 8, wherein the contextual policy further includes a user-defined instruction reflecting a policy to retrieve only workflow data associated with the identified application newly received at the remote data center.

10. The method of claim 8, wherein the contextual policy determines the workflow data to be pre-fetched by the virtual machine pre-fetch application by further comprising:

a command to retrieve workflow data to be pre-fetched by the virtual machine pre-fetch application and associated with a project upon occurrence of a calendared meeting for the project.

11. The method of claim 8, further comprising:

ejecting any stored pre-fetched workflow data from the storage device upon detecting that the user information handling system has roamed away from the wireless traffic area.

12. The method of claim 11, further comprising:

de-allocating the portion of storage at the micro-staging device for storing pre-fetched workflow data.

13. The method of claim 8, further comprising:

ejecting any stored pre-fetched workflow data from the storage device upon delivery of the pre-fetched workflow data to the user information handling system in the wireless traffic area.

14. The method of claim 8, further comprising:

de-allocating the portion of storage at the micro-staging device for storing pre-fetched workflow data after allocating the portion of storage at the micro-staging device upon detecting that the user information handling system has timed-out before detecting a data request from the user information handling system.

15. A computer-implemented method for pre-fetching data for delivery to a micro-staging device, the method comprising:

receiving a contextual policy at a remote data center via a backhaul connection to a wireless access point in a mesh WLAN network to determine pre-fetching of workflow data stored at the remote data center;

identification of a project associated with the pre-fetch request; and

identification of the workflow data associated with the project.
