A method and apparatus are described for providing a dynamic cache function in a network or cloud. A content cache server (CCS) and a lightweight CCS with a dynamic cache function may be deployed in the network or cloud. A tracker may be used to place dynamic cache peers in a peer list, and transmit the peer list to a wireless transmit/receive unit (WTRU). The peer list may include a single peer that is a dynamic cache peer allocated by the tracker to the WTRU, or at least two dynamic cache peers, with one additional “weight” parameter for each dynamic cache peer. The WTRU may connect to the dynamic cache peer with the largest “weight” parameter, and connect to a different dynamic cache peer in the peer list on a condition that the WTRU gets disconnected or gets bad service from the dynamic cache peer with the largest “weight” parameter.
