Abstract

A system, a computer readable storage medium including instructions, and a computer-implemented method of pre-fetching in a network, are provided. In an example embodiment, computer-implemented method of pre-fetching in a network comprises receiving a request from a user device for a first network-accessible data item in the plurality of network-accessible data items; transmitting the first network-accessible data item to the user device; identifying a second network-accessible data item in the plurality of network-accessible data items; and transmitting the second network-accessible data item to the user device, the second network-accessible data item being transmitted before receiving a request for the second network-accessible data item from the user device. Pre-fetch logic may be embedded in the first network-accessible data item.

Claims

1. A computer-implemented method of pre-fetching in a network, comprising:

receiving a request from a user device for a first network-accessible data item in the plurality of network-accessible data items;

transmitting the first network-accessible data item to the user device;

identifying a second network-accessible data item in the plurality of network-accessible data items; and

transmitting the second network-accessible data item to the user device, the second network-accessible data item being transmitted before receiving a request for the second network-accessible data item from the user device, and wherein prior to transmitting the first network-accessible data item the method further comprises embedding pre-fetch logic into the first network-accessible data item, the pre-fetch logic being executable by the user device or a server to cause the user device or the server to pre-fetch the second network-accessible data item.

2. The computer-implemented method of claim 1, wherein identifying a second network-accessible data item in the plurality of network-accessible data items further includes:

identifying the second network-accessible data item in the first network-accessible data item, and

retrieving the second network-accessible item based on the identification in the first network-accessible data item.

3. The computer-implemented method of claim 1, wherein the first network-accessible data item is upstream of the second network-accessible data item in a data item flow.

4. The computer-implemented method of claim 1, wherein transmitting the second network-accessible data item to the user device includes:

identifying a second network-accessible data item that is likely to be requested; and

transmitting the second network-accessible data item to the user device.

5. The computer-implemented method of claim 1, wherein transmitting the second network-accessible data item to the user device includes transmitting a portion of the second network-accessible data item to the user device.

6. The computer-implemented method of claim 5, wherein the portion of the second network-accessible data item includes static objects for the second network-accessible data item.

7. The computer-implemented method of claim 5, further comprising:

transmitting a remaining portion of the second network-accessible data item to the user device.

8. The computer-implemented method of claim 1, wherein prior to transmitting the second network-accessible data item to the user device, the method includes determining a data item flow for a plurality of network-accessible data items that includes the first network-accessible data item and the second network-accessible data item.

9. The computer-implemented method of claim 1, wherein the second network-accessible data item is transmitted to the user device only after the first network-accessible data item has been completely transmitted to the user device.

10. A system including hardware modules, comprising:

a receiving module to receive a request from a user device for a first network-accessible data item in a plurality of network-accessible data items; and

a transmitting module, implemented using one or more processors, to;

transmit the first network-accessible data item to the user device;

identify a second network-accessible data item in the plurality of network-accessible data items; and

transmit the second network-accessible data item to the user device, the second network-accessible data item being transmitted before receiving a request for the second network-accessible data item from the user device, and wherein prior to transmitting the first network-accessible data item, pre-fetch logic is embedded into the first network-accessible data item, the pre-fetch logic being executable by the user device or a server to cause the user device or the server to pre-fetch the second network-accessible data item.

11. The system of claim 10, wherein the transmitting module is further to identify the second network-accessible data item in the first network-accessible data item, and retrieve the second network-accessible item based on the identification in the first network-accessible data item.

12. The system of claim 10, further comprising a first processor to embed pre-fetch logic into the first network-accessible data item.

13. The system of claim 10, wherein the transmitting module is to transmit a portion of the second network-accessible data item to the user device.

14. The system of claim 13, wherein the portion of the second network-accessible data item includes static objects for the second network-accessible data item.

15. The system of claim 13, wherein the transmitting module is to transmit a remaining portion of the second network-accessible data item the user device.

16. The system of claim 10, further comprising:

a second processor;

wherein prior to transmitting the at least one network-accessible data item to the user device, the second processor is to determine a data item flow for the plurality of network-accessible data items that includes the first network-accessible data item and the second network-accessible data item.

17. The system of claim 10, wherein the second network-accessible data item is transmitted to the user device only after the first network-accessible data item has been completely transmitted to the user device.

18. A computer readable non-transitory storage medium storing at least one program configured for execution by a computer, the at least one program comprising instructions to:

receive a request from a user device for a first network-accessible data item in the plurality of network-accessible data items;

transmit the first network-accessible data item to the user device;

identify a second network-accessible data item in the plurality of network-accessible data items; and

transmit the second network-accessible data item to the user device, the second network-accessible data item being transmitted before receiving a request fir the second network-accessible data item from the user device, and wherein prior to transmitting the first network-accessible data item, pre-fetch logic is embedded into the first network-accessible data item, the pre-fetch logic being executable by the user device or a server to cause the user device or the server to pre-fetch the second network-accessible data item.
