Abstract

Embodiments of the present invention provide a method, system and computer program product for the dynamic structural management of an n-Tier distributed caching infrastructure. In an embodiment of the invention, a method of dynamic structural management of an n-Tier distributed caching infrastructure includes establishing a communicative connection to a plurality of cache servers arranged in respective tier nodes in an n-Tier cache, collecting performance metrics for each of the cache servers in the respective tier nodes of the n-Tier cache, identifying a characteristic of a specific cache resource in a corresponding one of the tier nodes of the n-Tier crossing a threshold, and dynamically structuring a set of cache resources including the specific cache resource to account for the identified characteristic.

First claim

We claim:

1. A method of dynamic structural management of an n-Tier distributed caching infrastructure, the method comprising:
establishing a communicative connection to multiple different cache servers arranged in respective tier nodes in an n-Tier cache;
collecting performance metrics for each of the cache servers in the respective tier nodes of the n-Tier cache;
identifying a characteristic of a specific cache resource of a corresponding one of the multiple different cache servers in a corresponding one of the tier nodes of the n-Tier that has a value which crosses a pre-determined threshold by identifying a utilization disparity amongst children cache servers supporting different cache clients in a common set of cache clients and a common parent cache server; and,
dynamically structuring a set of cache resources including the specific cache resource to account for the identified characteristic.

2. The method of claim 1 , wherein the utilization disparity is the underutilization of one of the cache servers.

3. The method of claim 2 , wherein dynamically structuring a set of cache resources including the specific cache resource to account for the identified characteristic, comprises consolidating caching support for the different cache clients of the common set of cache clients in the cache server demonstrating cache underutilization.

4. The method of claim 1 , wherein identifying a characteristic of a specific cache resource in a corresponding one of the tier nodes of the n-Tier crossing a threshold, comprises identifying a set of geographically proximate cache devices supporting a cache server instead of identifying a utilization disparity amongst children cache servers supporting different cache clients in a common set of cache clients and a common parent cache server.

5. The method of claim 4 , wherein dynamically structuring a set of cache resources including the specific cache resource to account for the identified characteristic, comprises establishing a partitioned cluster of the geographically proximate cache devices, the cache devices individually caching data pertaining to a corresponding unique topic assigned by the cache server.

6. The method of claim 5 , further comprising:
designating a plurality of the cache devices as a slave device assigned to cache data pertaining to a corresponding assigned topic; and,
designating one of the cache devices as a master device responsible for establishing a routing table of the different topics and distributing the routing table to each cache device designated as a slave device.
