System and method of selectively caching information based on the interarrival time of requests for the same information

A method comprising:ndetermining whether an item of information has been previously requested within a predetermined period;processing, with one or more processors, the item of information without storing the item in a cache when the item has not been previously requested within the predetermined period;processing, with the one or more processors, the item of information without storing the item of information in the cache when the item of information has been previously requested within the predetermined period and the time of the previous request is earlier than a latest request for each item within a set of items stored in the cache; andprocessing, with the one or more processors, the item of information and storing the item of information in the cache when the item of information has been previously requested within the predetermined period and the time of the previous request is later than the latest request of at least one item within the set of items stored in the cache.

A method comprising:ndetermining, with one or more processors, whether a first item of information has been previously requested within a predetermined period of time;determining, with the one or more processors, a first duration associated with the first item when the first item has been determined to have been previously requested, where the first duration is a duration of time between the current request for the first item and the previous request for the first item;determining, with the one or more processors, a second duration for each item of a set of previously-requested second items stored in memory, where the second duration is a duration of time between the current request for the first item and a latest request for the second item; andstoring the first item in the memory when the first item has been previously requested and the first duration is less than at least one of the second durations.

A method comprising:ndetermining, with one or more processors, a first value associated with a first item of information when the first item has been determined to have been previously requested, where the first value is based on a duration of time between previous requests for the first item;determining, with the one or more processors, a second value associated with each item of a set of previously-requested second items, where the second value is based on a duration of time between the current request for the first item and the latest request for the second item; andproviding the first item and storing the first item in a memory when the first item has been previously requested within a predetermined period of time, and based on a comparison of the first value with the second value.

A system comprising:none or more processors configured to retrieve and store items in a cache in accordance with instructions;the instructions causing the one or more processors, in response to a request from a requesting device for an item, to:nprovide the requested item to the requesting device, without storing the requested item in the cache prior to a next request, when the requested item has not been previously requested within a predetermined period;provide the requested item to the requesting device, without storing the requested item in the cache prior to the next request, when the requested item has been previously requested within a predetermined period and the time of the previous request is earlier than a latest request for each item within a set of items stored in the cache; andprovide the requested item to the requesting device, and storing the requested item in the cache prior to the next request, when the requested item has been previously requested within the predetermined period and the time of the previous request is later than the latest request of at least one item within the set of items stored in the cache.

A system comprising:none or more processors configured to retrieve and store items in memory in accordance with instructions;the instructions causing the one or more processors, in response to a request for an item received by the one or more processors, to:ndetermine a priority value for the requested item and a plurality of other items, wherein:the priority value is based on a priority function; andthe priority function is based on a duration of time between requests for the other items where less weight is applied to durations between earlier requests for the requested item; andstore the requested item in a first memory when:nthe requested item has been previously requested, the requested item is currently stored in a second memory, andthe priority value of the requested item is greater than the priority value of at least one of the other items stored in the first memory.
