Abstract

A system and method for pre-allocating resources for use by registering consumers of applications and/or services available via a protocol that identifies a user through items including, but not limited to, a cookie and/or a persistent connection (e.g., the Internet) is provided. The system includes one or more components for pre-allocating resources for use by consumers registering to use applications and/or services available over the Internet. Since consumers can be served by more than one application and/or service server, and since resources can be managed by more than one resource manager, information concerning a consumer may be replicated to the more than one resource manager. The system thus includes one or more components for processing requests from consumers that require access to resources so that requests from newly registered consumers can be processed by a resource manager that has information concerning the newly registered consumers.

Claims

1. A system for pre-allocating at least one resource, comprising:

an allocator that pre-allocates the at least one resource based at least in part on an association between the at least one resource and a first resource manager, a resource capacity and a resource location, the first resource manager is one of a plurality of collaborating resource managers that manage the at least one resource;

an identifier that determines whether a consumer utilizing the at least one resource is a registering consumer or a registered consumer;

an associator that associates the at least one pre-allocated resource with the first resource manager, the first resource manager operable to manage the at least one pre-allocated resource for the registering consumer;

a router that routes a request requiring access to the at least one resource associated with the registering consumer to the first resource manager, the router utilizes an algorithm to route the request to the first resource manager, the algorithm includes routing the request in a round-robin fashion to each of the collaborating resource managers based on an analysis of the request and mapping information that identifies which of the plurality of collaborating resource managers received replicated information and generated data associated with the registering consumer, wherein the request will not be routed to the plurality of collaborating resource managers that have not received replicated information and generated data associated with the registering consumer; and

a replicator that propagates information and generated data associated with the registering consumer to a disparate plurality of resource managers collaborating in managing the at least one resource and the router.

2. The system of claim 1, the at least one resource is allocated to a consumer registering to use an application.

3. The system of claim 2, the application is available over a network.

4. The system of claim 3, the network is the Internet.

5. The system of claim 1, the at least one resource is allocated to a consumer registering to use a service.

6. The system of claim 5, the service is available over the Internet.

7. The system of claim 1, the identifier is a computer process.

8. The system of claim 1, the associator is a computer process.

9. The system of claim 1, the router is a computer process.

10. The system of claim 1, the identifier operable to receive Hypertext Transfer Protocol (HTTP) requests.

11. The system of claim 10, the identifier distinguishes consumer requests by examining at least part of a persistent client side hypertext file (cookie).

12. The system of claim 1, the associator records association information concerning an association between the at least one resource and the first resource manager in one or more data structures.

13. The system of claim 12, the one or more data structures include at least one of, a table, an array, a list, a tree, a linked list, a hash and a heap.

14. The system of claim 12, the one or more data structures contain a mapping between the at least one resource and the first resource manager.

15. The system of claim 1, the associator records association information concerning an association between the at least one resource and the first resource manager in one or more databases.

16. The system of claim 15, the one or more databases contain a mapping between the at least one resource and the first resource manager.

17. The system of claim 1, the router accesses one or more data structures containing routing information that facilitates routing the request associated with the registering consumer to the first resource manager.

18. The system of claim 17, the one or more data structures include at least one of, a table, an array, a list, a tree, a linked list, a hash and a heap.

19. The system of claim 18, the one or more data structures contain one or more mappings for one or more consumers to one or more resource managers.

20. The system of claim 1, the router accesses one or more databases containing information that facilitates routing the request associated with the registering consumer to the first resource manager.

21. The system of claim 20, the one or more databases contain one or more mappings for one or more consumers to one or more resource managers.

22. A method for processing requests from a registering consumer, comprising:

pre-allocating one or more resources for one or more registering consumers based on resource type, resource location, resource capacity, resource availability and an association between the one or more resources and a first resource managing component that comprises one of a plurality of collaborating resource managers that manage the at least one resource;

determining whether data concerning the registering consumer has been replicated to a plurality of disparate resource managing components collaborating in managing the at least one resource;

associating one or more of the pre-allocated resources with the first resource managing component, the first resource managing component operable to manage the one or more pre-allocated resources for the registering consumer;

associating the registering consumer with the first resource managing component; and

routing a request from the registering consumer that requires access to a resource to the first resource managing component, the routing utilizes a round robin algorithm to direct the request to each of the plurality of collaborating resource managers based on an analysis of the request and mapping information that identifies which of the plurality of collaborating resource managers received replicated information and generated data associated with the registering consumer, wherein the request will not be routed to the plurality of collaborating resource managers that have not received replicated information and generated data associated with the registering consumer.

23. The method of claim 22, data associated with a registering consumer is replicated to one or more resource managers.

24. The method of claim 22, the request requiring access to the resource is not necessarily routed to the first resource manager if the data associated with registering consumer has been replicated to one or more resource managers, the request being routable to the one or more resource managers to which the data has been replicated.

25. The method of claim 22, the request requiring access to the resource is an HTTP request.

26. The method of claim 22, the registering consumer is registering to use at least one of an application and a service.

27. The method of claim 26, the application being available over the Internet.

28. The method of claim 26, the service being available over the Internet.

29. A computer readable medium having stored thereon computer executable instructions for carrying out the method of claim 22.

30. A system for pre-allocating at least one resource, comprising:

means for pre-allocating the at least one resource for consumption by a consumer based at least in part on a resource type, a resource capacity, a resource location, a resource availability and an association between the one or more resources and a first resource managing component that comprises one of a plurality of collaborating resource managers that manage the at least one resource;

means for determining whether data concerning the consumer has been replicated to one or more resource managing components collaborating in managing the at least one resource;

means for associating the at least one pre-allocated resource with a first resource managing component that acts in collaboration with a plurality of resource managing components, where the first resource managing component manages the at least one pre-allocated resource for the consumer before the data concerning the consumer has been replicated to the one or more resource managing components; and

means for routing a request generated by the consumer, for whom data has not been replicated to the one or more resource managing components, to the first resource managing component based on utilization of a round robin routing algorithm, an analysis of the request and mapping information that identifies which of the plurality of collaborating resource managers received replicated information and generated data associated with the registering consumer, wherein the request will not be routed to the plurality of collaborating resource managers that have not received replicated information and generated data associated with the registering consumer.
