Abstract: A system, computer readable medium and a method for caching, the method may include: determining to cache at least a certain data file piece of a data file; identifying at least one participating peer; requesting from the at least one participating peer, at least one of (i) a data file piece number of at least one data file piece that belongs to the data file; (ii) at least a segment of at least one data file piece; calculating an evaluated certain file piece size and a file pieces number estimation based on at least one response of at least one participating peer; and caching the certain data file piece in a cache module, in response to the evaluated certain data file piece size.

Abstract: A non-transitory computer readable medium and a method that may include receiving, at a first level cache that is coupled to a radio access network (RAN) component, a data entity that comprises an address; wherein each cache of the hierarchical group of caches is coupled to a component of the RAN or to a component of a core network that is coupled between the RAN and the Internet; identifying the data entity as comprising a request to receive information from a requesting entity that is wirelessly coupled to the RAN—if the address belongs to a root cache address range; providing the information, by the first level cache, to the requesting entity if the content is stored in the first level cache; and sending to an intermediate level cache the data entity if the information is not stored in the first level cache.
