Abstract

Systems and methods utilize a distributed server network to allow for the optimization of the upload of a data stream from a computing device. Performance metrics are estimated for different network paths from the computing device to a variety of entry servers in the distributed server network. Based on the estimated performance metrics, one or more entry servers are then selected to receive the data stream from the computing device. As a result, the systems and methods described herein allow for high quality upload performance which addresses the first mile vulnerability issues of the data stream. The distributed server network can then transmit copies of the data stream in real-time to other computing devices.

Claims

1. A method for managing entry of a data stream from a computing device into a distributed server network having a plurality of entry servers, the method comprising:

receiving an entry server assignment request including metadata by a first server and from the computing device to transmit the data stream into the distributed server network via a network, the metadata identifying;

a first geographic location of the computing device based on information input by a user of the computing device, and

a second geographic location of the computing device based on an IP address of the computing device;

identifying one or more servers of the distributed server network as a candidate to receive the data steam, the identification based on the metadata;

analyzing the entry server assignment request to select an entry server from the one or more servers of the plurality of entry servers to receive the data stream, the entry server selected based on one or more first estimated performance metrics for a first network path from the computing device to the entry server, the one or more first performance metrics estimated based on the first geographic location identified in the metadata;

analyzing the entry assignment request to select a backup entry server from the plurality of entry servers to receive the data stream, the backup entry server selected based on one or more second estimated performance metrics for a second network path from the computing device to the backup entry server, the one or more second performance metrics estimated based on the second geographic location identified in the metadata;

transmitting assignment data including entry server information by the first server in response to the entry server assignment request to the computing device, the assignment data requesting that the computing device transmit data in the data stream to the selected entry server; and

transmitting backup assignment data to the computing device requesting that the computing device further transmit data in the data stream to the selected backup entry server.

2. The method of claim 1, further comprising receiving the data in the data stream at the entry server.

3. The method of claim 1, wherein the data stream is a video data stream captured by a video recording device.

4. The method of claim 1, wherein the distributed server network is a content delivery network, and wherein the method further comprises transmitting the data stream to a second computing device during the entry of the data stream into the content delivery network.

5. The method of claim 4, wherein the data stream is a video data stream of an environment surrounding a user of the computing device during administration of an examination on the computing device, and wherein transmitting the data stream to the second computing device includes transmitting the video data stream for display on the second computing device during the administration of the examination.

6. The method of claim 1, wherein the estimated performance metrics include one or more performance metrics selected from a group consisting of bandwidth, packet loss, and delay.

7. The method of claim 1, wherein the assignment data transmitted to the computing device includes data representing an IP address of the entry server.

8. A non-transitory computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for managing entry of a data stream from a computing device into a distributed server network having a plurality of entry servers, the method comprising:

receiving an entry server assignment request including metadata by a first server from the computing device to transmit the data stream into the distributed server network via a network, the metadata identifying;

a first geographic location of the computing device based on information input by a user of the computing device, and

a second geographic location of the computing device based on an IP address of the computing device;

identifying one or more servers of the distributed server network as a candidate to receive the data steam, the identification based on the metadata;

analyzing the entry server assignment request to select an entry server from the one or more servers of the plurality of entry servers to receive the data stream, the entry server selected based on one or more first estimated performance metrics for a first network path from the computing device to the entry server, the one or more first performance metrics estimated based on the first geographic location identified in the metadata; and

analyzing the entry assignment request to select a backup entry server from the plurality of entry servers to receive the data stream, the backup entry server selected based on one or more second estimated performance metrics for a second network path from the computing device to the backup entry server, the one or more second performance metrics estimated based on the second geographic location identified in the metadata;

transmitting assignment data including entry server information by the first server in response to the entry server assignment request to the computing device, the assignment data requesting that the computing device transmit data in the data stream to the selected entry server; and

transmitting backup assignment data to the computing device requesting that the computing device further transmit data in the data stream to the selected backup entry server.

9. The non-transitory computer readable storage medium of claim 8, further comprising receiving the data in the data stream at the entry server.

10. The non-transitory computer readable storage medium of claim 8, wherein the data stream is a video data stream captured by a video recording device.

11. The non-transitory computer readable storage medium of claim 8, wherein the distributed server network is a content delivery network, and wherein the method further comprises transmitting the data stream to a second computing device during the entry of the data stream into the content delivery network.

12. The non-transitory computer readable storage medium of claim 11, wherein the data stream is a video data stream of an environment surrounding a user of the computing device during administration of an examination on the computing device, and wherein transmitting the data stream to the second computing device includes transmitting the video data stream for display on the second computing device during the administration of the examination.

13. The non-transitory computer readable storage medium of claim 8, wherein the estimated performance metrics include one or more performance metrics selected from a group consisting of bandwidth, packet loss, and delay.

14. The non-transitory computer readable storage medium of claim 8, wherein the assignment data transmitted to the computing device includes data representing an IP address of the entry server.
