Embodiment Construction

[0018] The present invention is a value-based caching process and system. In a value-based cache, the cache can be partitioned according to different value-based classifications corresponding to different data or consumer values. For simplicity, in the above description, three classifications are illustrated: Gold, Silver and Copper, but it should be understood that the present invention is not limited to any particular classification and that any other classification used as part of a differentiated calculation strategy is Different service levels may be provided to different consumers or different data. In any case, the cache replacement policy for each partition can be changed according to the value of the data stored in it.

[0019] Specifically, such a cache replacement policy may be provided so as to provide relatively longer cache leases for cached data in which the value of the cached data is lower than other values ​​in other partitions. Thus, for higher value cache...

Abstract

A value-based caching system and method. A value based cache method can include partitioning a cache into different value-based partitions. Data to be stored in the cache can be valued and the valued data can be cached in individual ones of the value-based partitions. Subsequently, cache entries can be evicted from the value-based partitions. Finally, the caching and evicting can be managed according to the valuing step. In this regard, the cache and eviction management step can ensure greater cache responsiveness for data having a greater value relative to other valued data.

Description

technical field [0001] The present invention relates to cache management and, in particular, to providing differentiated services in cache systems. Background technique [0002] Modern global networks can be viewed as complex networks intertwined with multiple network technologies, server platforms, client functions, and application requirements. The vast majority of networking technologies handle device requests indiscriminately. That is, every device request is processed with equal priority regardless of the identity of the requester or the type of request. However, with the exponential growth of network traffic on the Internet, recent network-oriented computing devices have begun to provide different computing service levels based on a technique called "policy-based service differentiation model." [0003] In a policy-based service differentiation model, a computing device can provide many levels of service, where different requests for different content or services fro...
