DYNAMIC CACHE SELECTION METHOD AND SYSTEM

摘要

Node, computer software and method for selecting a resource [20] that is available at multiple caches [14] connected in a communication network [80]. The method includes receiving from a user [18] a request for the resource [20]; identifying one or more caches [14a, 14b, 14c] of the multiple caches [14] that store the resource [20]; determining a total cost associated with a path between the user [18] and each cache [14a, 14b, 14c] of the one or more caches [14] storing the resource [20], the total cost including a static cost [Cf] that reflects a topology of the communication network [80] and a dynamic cost [?] which is indicative of changing conditions of the communication network [80]; and selecting one cache [14a] from the one or more caches [14a, 14b, 14c] that store the resource [20] based on a lowest total cost of the one cache [14a].
