Abstract

The present invention extends to methods, systems, and computer program products for optimizing access to federation infrastructure-based resources. Various different layers within a federation infrastructure can signal location change events indicating the hosting location and/or access location for a resource is to be optimized. In response to a location change event, redirection information for accessing the resource is updated within the federation infrastructure. The redirection information is used to redirect resource access requests to appropriately optimized locations within the federation infrastructure. Redirecting resource access requests reduces communication within the federation infrastructure.

Claims

1. At a computer system in a ring infrastructure, the computer system including one or more processors and system memory, the ring infrastructure including a ring of nodes, a method for providing optimized access to a ring infrastructure resource, the method comprising:

an act of receiving a user request to access a ring infrastructure resource, the user request sent from a requesting user component;

an act of detecting that the user request is not directed to an optimized location for accessing the ring infrastructure resource within the ring infrastructure based on processing information and one or more of;

the characteristics of the requesting user component and the characteristics of the user request; and

an act of sending an indication of an appropriately optimized location for the requesting user component to access the ring infrastructure resource based on the processing information and the one or more of;

the characteristics of the requesting user component and the characteristics of the user request.

2. The method as recited in claim 1, wherein the act of receiving a user request to access a ring infrastructure resource comprises an act of a node on the ring infrastructure receiving a user request to access a ring resource directly from the requesting user component.

3. The method as recited in claim 2, wherein the act of detecting that the user request is not directed to an optimized location for accessing the ring infrastructure resource comprises an act of detecting that the node is not the optimized location for accessing the ring infrastructure resource.

4. The method as recited in claim 3, wherein the act of sending an indication of an appropriately optimized location for the requesting user component to access the ring infrastructure resource comprise an act of the node sending an indication of the appropriately optimized location directly to the requesting user component, the appropriately optimized location being another node on the ring infrastructure.

5. The method as recited in claim 1, wherein the act of receiving a user request to access a ring infrastructure resource comprises an act of a node on the ring infrastructure receiving a user request to access a ring resource from a communication intermediary, the communication intermediary sending the user request on behalf of the requesting user component.

6. The method as recited in claim 5, wherein the act of detecting that the user request is not directed to an optimized location for accessing the ring infrastructure resource comprises an act of detecting that the node is not the optimized location for accessing the ring infrastructure resource.

7. The method as recited in claim 6, wherein the act of sending an indication of an appropriately optimized location for the requesting user component to access the ring infrastructure resource comprise an act of the node sending an indication of the appropriately optimized location directly to the communication intermediary, the appropriately optimized location being another node on the ring infrastructure.

8. The method as recited in claim 1, wherein the act of receiving a user request to access a ring infrastructure resource comprises an act of a communication intermediary receiving a user request to access a ring resource, the user request directed to a node on the ring infrastructure.

9. The method as recited in claim 8, wherein the act of detecting that the user request is not directed to an optimized location for accessing the ring infrastructure resource comprises an act of the communication intermediary detecting that the node is not the optimized location for accessing the ring infrastructure resource.

10. The method as recited in claim 9, wherein the act of sending an indication of an appropriately optimized location for the requesting user component to access the ring infrastructure resource comprise an act of the communication intermediary sending an indication of the appropriately optimized location to the user component, the appropriately optimized location being another node on the ring infrastructure

11. The method as recite din claim 1, wherein an act of sending an indication of an appropriately optimized location for the requesting user component to access the ring infrastructure resource comprises an act of sending a destination address for the appropriately optimized location to the requesting user component

12. At a computer system in a ring infrastructure, the computer system including one or more processors and system memory, the ring infrastructure including a ring of nodes, a method for optimizing access to a ring infrastructure resource, the method comprising:

an act of detecting a component request to optimize access to one or more ring infrastructure resources associated with the component on the ring of nodes so as to reduce inter-node communication costs between nodes on the ring of nodes;

an act of determining that the hosting location of an associated ring infrastructure resource, selected from among the one or more ring infrastructure resources, is not optimized on the ring of nodes based on one or more users of the component having a common interest in the associated resource; and

an act of indicating that the hosting location of the associated ring infrastructure resource on the ring of nodes is to be optimized to reduce inter-node communication costs between nodes on the ring nodes in response to the component request.

13. The method as recited in claim 12, wherein the act of detecting a component request to optimize access to one or more ring infrastructure resources comprises an act of receiving a request to optimize access to a ring infrastructure resource from a component of a communication service layer component.

14. The method as recited in claim 13, wherein the act of receiving a request to optimize access to a ring infrastructure resource from a communication service layer component comprises an act of receiving a request to optimize access to a ring infrastructure resource for one or more users having a common interest in the ring infrastructure resource.

15. The method as recited in claim 12, wherein an act of detecting a component request to optimize access to one or more ring infrastructure resources comprises an act of detecting that an application system has an application context associated with a resource hosted on the ring of nodes.

16. The method as recited in claim 15, wherein the act of indicating that the hosting location of the associated ring infrastructure resource on the ring of nodes is to be optimized to reduce inter-node communication costs comprise an act of sourcing an event to the application system.

17. The method as recited in claim 12, wherein the act of determining that the hosting location of an associated ring infrastructure resource is not optimized comprises:

an act of determining that the ring infrastructure resource is currently hosted at a first node on the ring of nodes; and

18. The method as recited in claim 12, wherein the act of optimizing the hosting location of the associated ring infrastructure resource comprise an act of moving the hosting location from a first node on the ring of nodes to a second node on the ring of nodes.
