Abstract

In the preferred embodiment of the present invention, the method retrieves a web file and sorts one or more information element references according to a priority attribute associated with each reference. After ranking the information element references by priority, the method then retrieves each information element in the order that their references were ranked. After receiving an information element, a user acts upon the information element in the appropriate manner. Typical objects, and their actions, would include displaying an image file, executing an applet, or playing an audio file. By using the steps of the preferred method, more important objects are retrieved before less important objects, thus allowing the user to act upon the more important objects sooner than the user could have acted on the important objects using methods available in the prior art.

Claims

1. A method executed in a computer network to facilitate acting on information elements, the computer network including at least a client computer and a server computer, the method comprising the steps of:

sorting a list of information elements so that the list is ranked from a first information element with a highest priority to a last information element with a lowest priority;

retrieving from the server computer to the client computer, the information elements in ranked order, and

displaying retrieved information elements in the order received,

wherein the step of retrieving the information elements further comprises the steps of;

determining whether at least one information element is currently being retrieved;

when the determination indicates that at least one information element is currently being retrieved, performing the following steps to facilitate retrieval of a next information element;

obtaining an indication of an available rate of incoming bandwidth to the client computer;

obtaining an indication of an available rate of outgoing bandwidth to the server computer;

determining a minimum rate of the available incoming bandwidth and the available outgoing bandwidth; and

accepting data associated with the next information element at a rate corresponding to a selected increment over the minimum rate.

2. The method of claim 1 wherein the selected increment is 10%.

3. The method of claim 1 wherein the available incoming bandwidth is a total incoming bandwidth minus the sum of the number of bits received from higher ranked objects running during a last time period.

4. The method of claim 3 wherein the total incoming bandwidth is, within a given time period, defined by,

determining a number of bits received from any source outside the computer system associated with the display device;

comparing the determined number of bits with the quantity of bits received over periods of time other than the given period of time; and

selecting the largest number of bits determined from the comparison as the total incoming bandwidth.

5. The method of claim 1 wherein the available bandwidth to the computer system storing the next information element is the total bandwidth to the computer system storing the next information element minus a sum of the number of bits received, during a given period, from retrieving an information element ranked higher than the next information element.

6. A computer program product to facilitate acting on information elements, in a computer network which includes a client computer and a server computer, the computer program product comprising:

code that (1) sorts a list of information elements so that the list is ranked from a first information element with a highest priority to a last information element with a lowest priority;

(2) retrieves from the server computer to the client computer, the information elements in ranked order, and (3) displays the information elements in the order retrieved,

wherein the code resides on a tangible medium,

wherein the step of retrieving the information elements further comprises;

code that determines whether at least one information element is currently being retrieved; and

code that performs the following steps to facilitate retrieval of a next information element, when the determination indicates that at least one information element is currently being retrieved,

code that obtains an indication of an available rate of incoming bandwidth to the client computer;

code that obtains an indication of an available rate of outgoing bandwidth to the server computer;

code that determines a minimum rate of the available incoming bandwidth and the available outgoing bandwidth; and

code that accepts data associated with the next information element at a rate corresponding to a selected increment over the minimum rate.

7. The computer program product of claim 6 wherein the selected increment is 10%.

8. The computer program product of claim 6 wherein the code that obtains the available incoming bandwidth includes code that determines a total incoming bandwidth minus the sum of the number of bits received from higher ranked objects being retrieved during a last time period.

9. The computer program product of claim 8 wherein the code that determines total incoming bandwidth, within a given time period, includes,

code that determines a number of bits received from any source outside the computer system associated with the display device;

code that compares the determined number of bits with the quantity of bits received over periods of time other than the given period of time; and

code that selects the largest number of bits determined from the comparison as the total incoming bandwidth.

10. The computer program product of claim 6 wherein the code that obtains available bandwidth to the computer system storing the next information element includes code that determines the total bandwidth to the computer system storing the next information element minus a sum of the number of bits received, during a given period, from retrieving an information element ranked higher than the next information element.

11. An apparatus to facilitate acting on information elements in a computer network the computer network including a client computer and a server computer, the apparatus comprising:

a mechanism configured to sort a list of information elements so that the list is ranked from a first information element with a highest priority to a last information element with a lowest priority; and

a mechanism configured to retrieve from the server computer to the client computer, and to display the information elements, both in ranked order,

wherein the mechanism configured to retrieve the information elements further comprises;

a mechanism configured to determine whether at least one information element is currently being retrieved;

a mechanism configured to perform the following steps to facilitate retrieval of a next information element, when the determination indicates that at least one information element is currently being retrieved,

a mechanism configured to obtain an indication of an available rate of incoming bandwidth to the client computer;

a mechanism configured to obtain an indication of an available rate of outgoing bandwidth to the server computer;

a mechanism configured to determine a minimum rate of the available incoming bandwidth and the available outgoing bandwidth; and

a mechanism configured to accept data associated with the next information element at a rate corresponding to a selected increment over the minimum rate.

12. The apparatus of claim 11 wherein the selected increment is 10%.

13. The apparatus of claim 11 wherein the available incoming bandwidth is a total incoming bandwidth minus the sum of the number of bits received from higher ranked objects running during a last time period.

14. The apparatus of claim 12 wherein the a mechanism configured to obtain the total incoming bandwidth is, within a given time period, includes,

a mechanism configured to determine a number of bits received from any source outside the computer system associated with the display device;

a mechanism configured to compare the determined number of bits with the quantity of bits received over periods of time other than the given period of time; and

a mechanism configured to select the largest number of bits determined from the comparison as the total incoming bandwidth.

15. The apparatus of claim 11 wherein the mechanism configured to obtain the available bandwidth to the computer system storing the next information element includes a mechanism configured to determine the total bandwidth to the computer system storing the next information element minus a sum of the number of bits received, during a given period, from retrieving an information element ranked higher than the next information element.
