Abstract

The present solution is directed towards systems and methods to more efficiently control a flow of a data stream traversing at least one intermediary on a network between a client and a server. A sender transmits a first message, comprising a first value of a bandwidth between the first intermediary and a second intermediary determined by the sender, to a first intermediary. The first intermediary establishes a next value of the bandwidth between the first intermediary and the second intermediary. The sender receives from the first intermediary responsive to the first message a second message comprising the established next value of the bandwidth between the first intermediary and the second intermediary. A data transfer manager of the sender, responsive to the second message determines a size of a portion of data queued for transmission to transmit to the first intermediary and a time for transmitting the portion of data queued.

Claims

1. A method of controlling flow of data communicated by a sender, the method comprising:

(a) identifying, by a data transfer manager of a sender, in a queue of data to be transmitted by the sender to a receiver via a computer network with a device intermediary to the sender and the receiver, between bulk data and interactive data generated by and requested to be transmitted to the receiver by an application on the sender, the device storing the bulk data and interactive data in the queue of data waiting for transmission to the receiver;

(b) receiving, by the data transfer manager, from the device backlog information of an amount of data transmitted by the sender to the receiver but still queued at the device to be transmitted by the device to the receiver, and at least one of a value of bandwidth between the device and the receiver or a compression ratio of compression of data between the device and the receiver; and

(c) determining, by the data transfer manager, a first amount of interactive data and a second amount of bulk data to be transmitted from the queue based on the backlog information comprising at least one of the value of bandwidth or the compression ratio; and

(d) updating, by the data transfer manager, the backlog information with the at least one of the value of bandwidth or the compression ratio.

2. The method of claim 1, wherein step (b) further comprises receiving, by the data transfer manager, from the device a value of bandwidth between the device and the receiver.

3. The method of claim 2, wherein step (c) further comprises determining the first amount of interactive data and the second amount of bulk data to be transmitted from the queue based on the backlog information and the value of bandwidth.

4. The method of claim 1, wherein step (b) further comprises receiving, by the data transfer manager, from the device a compression ratio of compression of data between the device and the receiver.

5. The method of claim 4, wherein step (c) further comprises determining the first amount of interactive data and the second amount of bulk data to be transmitted from the queue based on the backlog information and the compression ratio.

6. The method of claim 1, wherein step (a) further comprises identifying from the data generated by the application the bulk data comprising data that is not real time data.

7. The method of claim 1, wherein step (a) further comprises identifying from the data generated by the application the interactive data comprising data that is real time data.

8. The method of claim 1, wherein step (a) further comprises distinguishing between interactive data and bulk data from the data generated by the application.

9. The method of claim 1, wherein step (b) further comprises receiving, by the data transfer manager, from the device backlog information comprising an amount of data in a second queue of the device waiting to be transmitted by the device to the receiver.

10. The method of claim 1, wherein step (c) further comprises determining, by the data transfer manager based on the backlog information, a first timing of a first amount of bulk data and a second timing of a second amount of interactive data from the queue to be sent by the sender.

11. A system for controlling flow of data communicated by a sender, the system comprising:

a sender comprising at least a processor coupled to a memory and in communication via a computer network with a device intermediary to the sender and a receiver;

wherein the memory stores computer executable instructions that when executed by the processor performs the operations of a data transfer manager of the sender to identify, in a queue of data to be transmitted by the sender to the receiver, between bulk data and interactive data generated by and requested to be transmitted to the receiver by an application on the sender, the device storing the bulk data and interactive data in the queue of data waiting for transmission to the receiver; and

receive from the device backlog information of an amount of data transmitted by of the sender but still queued at the device to be transmitted by the device to the receiver and at least one of a value of bandwidth between the device and the receiver or a compression ratio of compression of data between the device and the receiver, determine a first amount of interactive data and a second amount of bulk data to be transmitted from the queue based on the backlog information comprising at least one of the value of bandwidth or the compression ratio; and

update the backlog information with the at least one of the value of bandwidth or the compression ratio.

12. The system of claim 11, wherein the data transfer manager is further configured to receive from the device a value of bandwidth between the device and the receiver.

13. The system of claim 12, wherein the data transfer manager is further configured to determine the first amount of interactive data and the amount of bulk data to be transmitted from the queue based on the backlog information and the value of bandwidth.

14. The system of claim 11, wherein the data transfer manager is further configured to receive from the device a compression ratio of compression of data between the device and the receiver.

15. The system of claim 14, wherein the data transfer manager is further configured to determine the first amount of interactive data and the second amount of bulk data to be transmitted from the queue based on the backlog information and the compression ratio.

16. The system of claim 11, wherein the bulk data comprises data that is not real time data.

17. The system of claim 11, wherein the interactive data comprises data that is real time data.

18. The system of claim 11, wherein the data transfer manager is further configured to distinguish between interactive data and bulk data from the data generated by the application.

19. The system of claim 11, wherein the data transfer manager is further configured to receive from the device backlog information comprising an amount of data in a second queue of the device waiting to be transmitted by the device to the receiver.

20. The system of claim 11, wherein the data transfer manager is further configured to determine based on the backlog information, a first timing of the first amount of interactive data and a second timing of the second amount of bulk data from the queue to be sent by the sender.
