A system for resource allocation in peer to peer streaming includes steps of: inferring global properties of a neighborhood made up of peer nodes, wherein the global properties are inferred from a summarization of information obtained locally at each peer node; allocating resources for each peer node to its neighbor nodes in accordance with propagated dependency information; and periodically updating the target rates as peer nodes join and leave the neighborhood.

A method includes the steps of: detecting a request from a client to restart a streamed multimedia presentation from a new starting point; determining if an update to a source file of the streamed multimedia presentation is available; if the update is available: closing the source file, opening the update, and establishing a link to the existing data channel; locating the new starting point of the streamed multimedia presentation; and streaming the multimedia presentation from the new starting point.

Exemplary illustrative embodiments provide for a method implemented in a service oriented architecture environment including a plurality of live services. The method includes composing, at runtime, a composed service by mapping a first parameter of a first subset of live services to a second parameter of a second subset of live services. The first subset and the second subset are part of the plurality of live services. The method can further include storing the composed service in a memory.

The invention provides a method, system, and program product for optimizing data exchange in a peer-to-peer network (PTPN). In one embodiment, the invention provides a method of optimizing real-time data exchange in a peer-to-peer network (PTPN), the method comprising: receiving, from each peer in the PTPN: an upload limit of the peer; a download limit of the peer; and a delay to each other peer in the PTPN; determining, for each peer in the PTPN: a rate at which data may be transferred to at least one other peer in the PTPN (transfer rate); and a rate at which data may be received from at least one other peer in the PTPN (receive rate); and instructing each peer in the PTPN to: transfer data to at least one other peer in the PTPN at the transfer rate; and receive data from at least one other peer in the PTPN at the receive rate.
