Abstract: A method for providing information to a client over a peer-to-peer network, the method includes: receiving, by a tracker proxy, a re-directed first request of a client to access a tracker; and sending, by the tracker proxy, a first response that identifies a network cache as a peer. A method for providing a video file to a client, the method includes: receiving a request of a client to retrieve a video file from a web site or another external source out of multiple requests that are sent to multiple information sources; and providing to the client cache a first response that identifies a network cache as a source of the video file.

Abstract: A non-transitory computer readable medium, a system and a method for streaming, the method may include: intercepting, by a redirector, a request from a streaming application, to receive metadata indicative of location of multiple video file segments; sending to the streaming application metadata that points to locations of cached video file segments within a single streaming cache or multiple streaming caches and points to locations outside the streaming cache of other video file segments that are not cached; receiving, by the streaming cache, a request from the streaming application to receive a cached video file segment; sending from the streaming cache the cached video file segment.

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.

Abstract: A system, a method and a computer program product for transmission over a network, the method includes: receiving, by an intermediate system coupled to the network, a portion of a data structure that is aimed to a recipient computer; generating a stamp that is responsive to a content of a segment of the data structure and is indifferent to transfer information about a transmission of the data structure; wherein the portion may include the segment or equals the segment; determining, by the intermediate system, whether to cache the portion, in response to at least a comparison between the stamp and stamps of cached portions of data structures; selectively caching the portion in response to the determination; and transmitting to the recipient computer either one of the portion of the transmitted data structure and a cached version of the portion of the transmitted data structure.
