Abstract

A method that limits data flow between two network nodes to an amount within a window where a first portion of data within a first segment of the window is separated from a second portion of data within a second segment of the window by a third portion of data not within the window.

Claims

1. A method, comprising:

receiving at a client transport layer a request from a client application;

at said client transport layer, controlling the flow of information corresponding to a client'"'"'s reception of said request'"'"'s response, said controlling comprising;

sending a request for a first contiguous portion of said response;

receiving a first section of said first contiguous portion;

not receiving a second section of said first contiguous portion;

receiving a third section of said first contiguous portion, where, said first section precedes said second section and said second section precedes said third section in said first contiguous portion'"'"'s sequence order;

sending a request for a second contiguous portion of said response, said second contiguous portion corresponding to a next contiguous portion of said response immediately following said first contiguous portion in said response'"'"'s sequence order, said second contiguous portion having a size corresponding to said first contiguous portion'"'"'s size less said second section'"'"'s size; and

,

continuously requesting and receiving, while said second section remains not received and said client remains waiting to receive said second section, subsequent contiguous portions of said response in order of said response'"'"'s sequence order such that a window of said second contiguous portion'"'"'s size effectively slides without limit toward the end of said response.

2. The method of claim 1 wherein said requests are sent to a server.

3. The method of claim 1 further comprising a size of said requested first contiguous portion of said response being determined by said client in view of networking traffic flow conditions monitored by said client.

4. The method of claim 1 wherein said request from said client application to said client transport layer is for a data object held by a server that provides said response.

5. The method of claim 4 wherein said client application provides an IP address to said client transport layer, said IP address corresponding to said server'"'"'s IP address.

6. The method of claim 1 wherein said request from said client application to said client transport layer is for a server to take an action on a data object, said response corresponding to a result of said action.

7. A machine readable storage medium having program code as opposed to transitory electromagnetic signals stored thereon that when processed by a computer cause the computer to perform a method, the method comprising:

receiving at a client transport layer a request from a client application;

at said client transport layer, controlling the flow of information corresponding to a client'"'"'s reception of said request'"'"'s response, said controlling comprising;

sending a request for a first contiguous portion of said response;

receiving a first section of said first contiguous portion;

not receiving a second section of said first contiguous portion;

receiving a third section of said first contiguous portion, where, said first section precedes said second section and said second section precedes said third section in said first contiguous portion'"'"'s sequence order;

sending a request for a second contiguous portion of said response, said second contiguous portion corresponding to a next contiguous portion of said response immediately following said first contiguous portion in said response'"'"'s sequence order, said second contiguous portion having a size corresponding to said first contiguous portion'"'"'s size less said second section'"'"'s size; and

,

continuously requesting and receiving, while said second section remains not received and said client remains waiting to receive said second section, subsequent contiguous portions of said response in order of said response'"'"'s sequence order such that a window of said second contiguous portion'"'"'s size effectively slides without limit toward the end of said response.

8. The machine readable storage medium of claim 7 wherein said requests are sent to a server.

9. The machine readable storage medium of claim 7 wherein said method further comprises a size of said requested first contiguous portion of said response being determined by said client in view of networking traffic flow conditions monitored by said client.

10. The machine readable storage medium of claim 7 wherein said request from said client application to said client transport layer is for a data object held by a server that provides said response.

11. The machine readable storage medium of claim 10 wherein said client application provides an IP address to said client transport layer, said IP address corresponding to said server'"'"'s IP address.

12. The machine readable storage medium of claim 7 wherein said request from said client application to said client transport layer is for a server to take an action on a data object, said response corresponding to a result of said action.

13. A computer having a readable storage medium containing program code that when read from said storage medium and processed by said computer causes said computer to perform a method, comprising:

receiving at a client transport layer a request from a client application;

at said client transport layer, controlling the flow of information corresponding to a client'"'"'s reception of said request'"'"'s response, said controlling comprising;

sending a request for a first contiguous portion of said response;

receiving a first section of said first contiguous portion;

not receiving a second section of said first contiguous portion;

receiving a third section of said first contiguous portion, where, said first section precedes said second section and said second section precedes said third section in said first contiguous portion'"'"'s sequence order;

sending a request for a second contiguous portion of said response, said second contiguous portion corresponding to a next contiguous portion of said response immediately following said first contiguous portion in said response'"'"'s sequence order, said second contiguous portion having a size corresponding to said first contiguous portion'"'"'s size less said second section'"'"'s size; and

,

continuously requesting and receiving, while said second section remains not received and said client remains waiting to receive said second section, subsequent contiguous portions of said response in order of said response'"'"'s sequence order such that a window of said second contiguous portion'"'"'s size effectively slides without limit toward the end of said response.

14. The machine readable storage medium of claim 13 wherein said requests are sent to a server.

15. The machine readable storage medium of claim 13 wherein said method further comprises a size of said requested first contiguous portion of said response being determined by said client in view of networking traffic flow conditions monitored by said client.

16. The machine readable storage medium of claim 13 wherein said request from said client application to said client transport layer is for a data object held by a server that provides said response.

17. The machine readable storage medium of claim 16 wherein said client application provides an IP address to said client transport layer, said IP address corresponding to said server'"'"'s IP address.

18. The machine readable storage medium of claim 13 wherein said request from said client application to said client transport layer is for a server to take an action on a data object, said response corresponding to a result of said action.
