Abstract: A method and an apparatus for acquiring a contribution value of a transfer node are disclosed. The method includes: acquiring charging information of a trust node which is in a trust network circumstance and joining in a session, and acquiring charging information of the transfer node which is in a distrust network circumstance and joining in the session; auditing the consistency of charging information between the transfer node and the trust node; computing the contribution value of the transfer node according to the auditing result and the charging information of the transfer node. The invention can effectively guarantee acquiring the contribution value of the transfer node truly and unfailingly in a distrust circumstance of network circumstance, and subsequently providing basis for rewarding the node which has contributed for transferring.

Abstract: A system, a method and an apparatus for distributing streaming media, include that a terminal node sends the inquiry request carrying the address information of itself to a global server; the global server determines the affiliated domain of the terminal node according to the address information, and returns the domain server information of the affiliated domain; the terminal node sends streaming media data obtaining request to the domain server of the affiliated domain; the domain server of the affiliated domain inquires whether there is the streaming media data in its local domain; if yes, the streaming media data is returned and/or the information of the other terminal nodes which have the streaming media data in their local domains is returned; if not, the requested streaming media data is obtained from the other domain servers in the core network and/or the global server and sent to the terminal node by the way of P2P; the terminal node receives the returned streaming media data and/or obtains the reques
