Abstract

A system and method is provided whereby more requests than are necessary to obtain a network resource may be adaptively determined and preemptively transmitted from a client device to a server device in order to reduce latency caused by the delay or loss of a request. In one aspect, the system and method includes transmitting multiple connection requests from the client to the server, where the number of the connection requests transmitted to the server is greater than the number necessary to obtain a resource hosted by the server.

Claims

1. A method for transmitting a request from one node of a network to another node of the network, the method comprising:

receiving, at an initiation node, a resource request for a desired resource hosted at a destination node;

adaptively determining, with a processor, a plurality of connection request packets, and preemptively transmitting the plurality of connection request packets from the initiation node to the destination node to obtain the desired resource;

establishing, in accordance with a first network protocol, one or more connections between the initiation node and the destination node, the one or more connections being established based on respective response packets from the destination node to one or more of the preemptively transmitted plurality of connection request packets, the one or more established connections including a first established connection established prior to any other established connections;

automatically selecting, at the initiation node, the first established connection to the destination node and adding the first established connection to a pool of usable connections;

transmitting the resource request to the destination node via the first established connection.

2. The method of claim 1, further comprising:

receiving, from the destination node, first data responsive to the resource request via the first established connection;

adding, at the initiation node, at least one additional established connection to the pool of usable connections, the at least one additional established connection established after the first established connection; and

,

requesting and receiving, after the first data is received, second data and third data from the destination node, the second and third data requested and received via the first established connection and the at least one additional established connection respectively.

3. The method of claim 1, wherein the first network protocol comprises a TCP/IP protocol.

4. The method of claim 1 wherein upon receipt of the resource request at the initiation node, the method further comprises preemptively transmitting, in accordance with a second network protocol, an adaptively determined plurality of address resolution requests to a domain name server to obtain a network address of the destination node.

5. The method of claim 4, wherein the second network protocol comprises a domain name resolution protocol.

6. The method of claim 1, wherein the resource request comprises a URL.

7. The method of claim 1, wherein each of the one or more connections is a TCP connection between the initiation node and the destination node.

8. The method of claim 1, wherein the plurality of connection request packets are adaptively determined based on an analysis of data collected with respect to previous requests transmitted by the initiation node to the destination node.

9. The method of claim 1, wherein the plurality of connection request packets are adaptively determined based on an analysis of data collected with respect to a previous request for the desired resource transmitted by the initiation node to the destination node.

10. A method for transmitting data from one node of a network to another node of the network, the method comprising:

receiving, at an initiation node, a resource request for a desired resource hosted at a destination node;

transmitting a first request, from the initiation node to the destination node over the network, to obtain the desired resource;

defining, at the initiation node, a timeout window with a processor, the timeout window being associated with the transmission of the first request and setting a maximum timeframe, in accordance with a network protocol, for receiving a first reply from the destination node responsive to the first request; and

,

preemptively transmitting, from the initiation node to the destination node over the network, at least one additional request to obtain the desired resource, wherein the at least one additional request is transmitted to the destination prior to receiving the first reply at the initiation node and prior to expiration of the maximum timeframe set by the timeout window.

11. A system for transmitting data over a network, the system comprising:

a memory storing instructions and data, the data comprising a resource request for a desired resource hosted at a destination node;

a processor to execute the instructions and to process the data;

wherein the instructions comprise;

adaptively determining, with the processor, a plurality of connection request packets, and preemptively transmitting the plurality of connection request packets from an initiation node to the destination node to obtain the desired resource;

establishing, in accordance with a first network protocol, one or more connections between the initiation node and the destination node, the one or more connections being established based on respective response packets from the destination node to one or more of the preemptively transmitted plurality of connection request packets, the one or more established connections including a first established connection established prior to any other established connections;

automatically selecting, at the initiation node, the first established connection to the destination node and adding the first established connection to a pool of usable connections;

transmitting the resource request to the destination node via the first established connection.

12. The system of claim 11, wherein the instructions further comprise:

receiving, from the destination node, first data responsive to the resource request via the first established connection;

adding, at the initiation node, at least one additional established connection to the pool of usable connections, the at least one additional established connection established after the first established connection; and

,

requesting and receiving, after the first data is received, second data and third data from the destination node, the second and third data requested and received via the first established connection and the at least one additional established connection respectively.

13. The system of claim 11, wherein the first network protocol comprises a TCP/IP protocol.

14. The system of claim 11, wherein the instructions further comprise preemptively transmitting, in accordance with a second network protocol, an adaptively determined plurality of address resolution requests to a domain name server to obtain a network address of the destination node.

15. The system of claim 14, wherein the second network protocol comprises a domain name resolution protocol.

16. The system of claim 11, wherein the resource request comprises a URL.

17. The system of claim 11, wherein each of the one or more connections is a TCP connection between the initiation node and the destination node.

18. The system of claim 11, wherein the plurality of connection request packets are adaptively determined based on an analysis of data collected with respect to previous requests transmitted by the initiation node to the destination node.

19. The system of claim 11, wherein the plurality of connection request packets are adaptively determined based on an analysis of data collected with respect to a previous request for the desired resource transmitted by the initiation node to the destination node.

20. A system comprising:

a memory storing instructions and data, the data comprising a resource request for a desired resource hosted at a destination node;

a processor to execute the instructions and to process the data;

wherein the instructions comprise;

transmitting a first request, from the initiation node, to the destination node to obtain the desired resource;

defining, at the initiation node, a timeout window with a processor, the timeout window being associated with the transmission of the first request and setting a maximum timeframe, in accordance with a network protocol, for receiving a first reply from the destination node responsive to the first request; and

,

preemptively transmitting, from the initiation node to the destination node, at least one additional request to obtain the desired resource, wherein the at least one additional request is transmitted to the destination prior to receiving the first reply at the initiation node and prior to expiration of the maximum timeframe set by the timeout window.
