Abstract

A method and an intermediate component for controlling in a communications network an object transfer from a first network component via the intermediate component to a second network component which is remote from the first network component are described. The object transfer is based on a plurality of object requests relating to objects referred to in one or more codes to be processed by the second network component or another network component. The intermediate component forms the steps of sending an object request to the first network component, receiving the requested object from the first network component, updating and/or assessing a priority of the requested object, and, in dependence of the priority of the requested object, delaying the requested object or forwarding the requested object to the second network component. An initial priority is assigned to the requested objects on the basis of an analysis of at least one of the object request and the code that refers to the requested object.

Claims

1. A method, in a communications network, of controlling an object transfer from a first component to a second component remote from the first component, wherein the object transfer is based on a plurality of object requests relating to objects referred to in one or more codes to be processed by the second or another component of the communications network, the method comprising steps of:

utilizing an intermediate component positioned between the first and the second component for;

sending an object request to the first component;

receiving the requested object from the first component;

estimating traffic over a link, comprising a number of connections, between the intermediate component and the second component to determine whether the link is fully used before suspending a connection to avoid wasting available bandwidth;

dynamically assigning a priority to the requested object, wherein an initial priority has been assigned to the requested object on the basis of an analysis of at least one of the object request and the code that refers to the requested object; and

depending on the priority of the requested object, the intermediate component delaying the requested object when the requested object has a priority that is below a threshold priority and forwarding the requested object to the second component when the requested object has a priority that is above said threshold priority,

wherein delaying of the requested object includes at least one of

instructing the second component to repeat the object request, wherein instructing the second component to repeat the object request includes;

assigning a specific attribute to the object to be delayed;

informing the second component of the attribute;

receiving a reference to the attribute from the second component; and

upon receipt of the reference to the attribute, sending the delayed object to the second component or further delaying the delayed object;

suspending a connection to the second component via which the requested object is to be forwarded, and

informing the second component that the requested object will automatically be forwarded at a later point in time.

2. The method of claim 1, wherein the delaying is performed such that an order in which the objects are received from the first component differs from the order in which the objects are forwarded to the second component.

3. The method of claim 1, wherein the object request is received from the second component or generated by the intermediate component.

4. The method of claim 1, further comprising:

sending a code request to the first or a third component;

receiving the requested code from the first or the third component;

analyzing the received code with respect to references to objects;

assessing the references to objects with the purpose of assigning initial priorities to the objects referred to in the received code.

5. The method of claim 1, wherein upon receipt of a response containing the object requested from the first component, the response is evaluated with respect to a received object'"'"'s priority in order to determine whether or not an initial priority of the received object has to be updated.

6. The method of claim 1, further comprising generating a priority list that contains priority information for individual objects or classes of objects.

7. The method of claim 6, further comprising repeatedly assessing the priority list with respect to at least one of updating priority information, deleting objects or classes of objects and corresponding information, from the priority list.

8. The method of claim 1, wherein the steps are performed by a proxy component situated on the first component, on the second component or configured as a separate hardware component of the communications network.

9. A method in a communications network, of controlling an object transfer from a first component to a second component remote from the first component, wherein the object transfer is based on a plurality of object requests relating to objects referred to in one or more codes to be processed by the second or another component of the communications network, the method comprising steps of:

utilizing an intermediate component positioned between the first and the second component for;

sending an object request to the first component;

receiving the requested object from the first component;

estimating traffic over a link, comprising a number of connections, between the intermediate component and the second component to determine

whether the link is fully used before suspending a connection to avoid wasting available bandwidth;

dynamically assigning a priority to the requested object, wherein an initial priority has been assigned to the requested object on the basis of an analysis of at least one of the object request and the code that refers to the requested object; and

depending on the priority of the requested object, the intermediate component delaying the requested object when the requested object has a priority that is below a threshold priority and forwarding, when the priority of the requested object is above the threshold priority, the requested object via the number of connections to the second component, based on comparing an average throughput of the number of connections to the second component to an amount of data that is currently cached or buffered in the intermediate component.

10. The method of claim 9, wherein selected ones of the number of connections to the second component are suspended dependent upon the priority of the requested object that is received from the first component and that is to be forwarded via the selected ones of the connections.

11. The method of claim 9, further including the step of dynamically allocating a specific share of processing capabilities to each of the number of connections.

12. The method of claim 9, further comprising:

sending a code request to the first or a third component;

receiving the requested code from the first or the third component;

analyzing the received code with respect to references to objects;

assessing the references to objects with the purpose of assigning initial priorities to the objects referred to in the received code.

13. The method of claim 9, wherein upon receipt of a response containing the object requested from the first component, the response is evaluated with respect to the received object'"'"'s priority in order to determine whether or not the initial priority of the received object has to be updated.

14. The method of claim 9, further comprising generating a priority list that contains priority information for individual objects or classes of objects.

15. The method of claim 14, further comprising repeatedly assessing the priority list with respect to at least one of updating priority information, deleting objects or classes of objects and corresponding information, from the priority list.

16. The method of claim 9, wherein the steps are performed by a proxy component situated on the first component, on the second component or configured as a separate hardware component of the communications network.

17. The method of claim 9, wherein the delaying is performed such that an order in which the objects are received from the first component differs from the order in which the objects are forwarded to the second component.

18. The method of claim 9, wherein the object request is received from the second component or generated by the intermediate component.

19. The method of claim 9, wherein delaying of the requested object includes at least one of

instructing the second component to repeat the object request,

suspending a connection to the second component via which the requested object is to be forwarded, and

informing the second component that the requested object will automatically be forwarded at a later point in time.

20. The method of claim 19, wherein instructing the second component to repeat the object request includes:

assigning a specific attribute to the object to be delayed;

informing the second component of the attribute;

receiving a reference to the attribute from the second component; and

upon receipt of the reference to the attribute, sending the delayed object to the second component or further delaying the delayed object.

21. An apparatus in a communications network for controlling an object transfer from a first component to a second component which is remote from the first component, wherein the object transfer is based on a plurality of object requests relating to objects referred to in one or more codes to be processed by the second component of the communications network, the apparatus comprising:

an intermediate component between the first component and the second component;
