One embodiment provides a system and a method for presenting streaming media content delivered through a peer-to-peer overlay network. During operation, a data-transfer mechanism sends requests to a plurality of peer nodes to receive data for streaming media content. The system stores received data for the streaming media content into a buffer. Next, a server local to a media presentation mechanism serves the buffered data to a media presentation mechanism. The server controls the data serving in response to a signal received from the media-presentation mechanism.

One embodiment provides a method and a system for expediting content delivery in a peer-to-peer overlay network. A local cache and directory server caches a multiplicity of segments for multi-media content, and maintains a mapping between cacheable content and one or more local partner nodes that transiently stage segments for the cacheable content. The local cache and directory server receives a request identifying requested content, which may or may not be cached or mapped. The cache and directory server determines a match to the requested content in the mapping and sends a list of local partner nodes that transiently stage segments for the requested content based on the match.

System and method for buffering real-time streaming content in a peer-to-peer overlay network
One embodiment provides a system and method for synchronously buffering real-time streaming content in a peer-to-peer overlay network to improve inter-peer-node synchronization. A requesting peer node identifies a partner peer node that transiently stages content segments. The requesting peer node determines the status of its local buffer and sends a request that indicates such status to a partner peer node. After receiving the most recent segment not present in the buffer from the partner peer node, the requesting peer node transiently stages the received segments in the buffer.

Broadcast messaging in peer to peer overlay network
ActiveUS20070121570A1Without wastingEfficiently directsError preventionFrequency-division multiplex detailsS/KEYPeer to peer overlay networks
Broadcast messages are efficiently directed to nodes of an overlay network. Broadcast messages include an End ID parameter specifying the range of key values for nodes that should receive the broadcast message. Each node of an overlay network maintains a list of finger nodes and their respective key values. Upon receiving a broadcast message, a node assigns a finger node a new End ID value based upon the End ID value of the broadcast message or the key value of an adjacent finger node. The node compares a finger node's new End ID value with the finger node's key value to determine whether to forward the broadcast message to that finger node. A broadcast message forwarded to a finger node includes an End ID parameter equal to the new End ID value determined for the finger node. Nodes can aggregate response messages from its finger nodes.

Information codes are arranged in pieces comprised of chunks of bytes over a network, such as a Peer-to-Peer overlay network, including a set of peer terminals. A first peer identifies missing chunks in the received pieces and requests such missing chunks from other peers. The chunks are subjected to a fountain code encoding wherein the chunks in a piece are X-ORed. The first peer is therefore capable of reconstructing a received piece encoded with fountain codes from a combination of linearly independent chunks corresponding to the piece. The chunks are transmitted over the network with a connection-less protocol, without retransmission of lost packets, preferably with a UDP protocol.

Application level broadcast in peer overlay network
A broadcast message may be initiated or received at a peer node. The node obtains an uplink bandwidth available for broadcasting the message over the network and a number of copies that can be broadcast based on the available bandwidth. The node determines a range of key values for finger nodes that should receive copies of the broadcast message from a finger table. The finger table entries include references to finger nodes and key values associated with the finger nodes. The node determines which other nodes should receive copies of the broadcast message from range of key values and the number of copies. The node also determines an End ID for each recipient node. A copy of the broadcast message and corresponding End ID is sent to a finger node if the finger node's key value is within a range of key values specified by the End ID.

A multi-party commitment method is provided whereby a joining node uses contributions provided by contributor nodes in a peer-to-peer overlay network to generate a node identifier. The joining node generates a first contribution and sends a join request to an introducer node (or a plurality of contributor nodes), where the join request seeks to obtain one or more contributions for generating the node identifier within an identifier space of the overlay network. A hash of the first contribution may be included as part of the join request. In response, the joining node may receive a plurality of contributions, wherein the contributions are bound to each other and the first contribution by a prior external multi-node commitment operation. The joining node can then generate its node identifier as a function of the first contribution and the received contributions. Consequently, collusion between nodes and malicious manipulation during ID generation can be frustrated.
