A HCPS (hierarchically clustered P2P streaming system) comprising peers grouped into clusters and hierarchies. The HCPS actively balances the uploading capabilities among clusters and executes an optimal scheduling algorithm within each cluster to ensure that system resources are optimally utilized. The HCPS comprises an architecture which can be used in practical applications, yet can achieve the streaming rate close to the theoretical upper bound.

A method and apparatus are described for scheduling content delivery in a peer-to-peer network, including receiving a message from a peer, classifying the received message, storing the classified message in one of a plurality of queues based on the classification, generating responses to messages based on a priority of the queue in which the classified message is stored and transmitting content to all peers in the peer-to-peer network. Also described are a method and apparatus for scheduling content delivery in a peer-to-peer network, including receiving one of a message and content from one of a content source server and a peer, classifying the received message, storing the classified message in one of a plurality of queues based on the classification, storing the received content, generating responses to messages based on a priority of the queue in which the classified message is stored and transmitting content to all other peers in the peer-to-peer network.

A method and apparatus are described including forwarding data in a transmission queue to a first peer in a same cluster, computing an average transmission queue size to a threshold, sending a signal to a cluster head based on a result of the comparison. A method and apparatus are also described including forwarding data in a transmission queue to a peer associated with an upper level peer, forwarding data in a playback buffer to a peer in a lower level cluster responsive to a first signal in a signal queue associated with the lower level cluster, determining if the playback buffer has exceeded a threshold for a period of time, sending a second signal to a source server based on a result of the determination.

A method and apparatus are described including receiving data from a plurality of cluster heads and forwarding the data to peers. Also described are a method and apparatus including calculating a sub-stream rate, splitting data into a plurality of data sub-streams and pushing the plurality of data sub-streams into corresponding transmission queues. Further described are a method and apparatus including splitting source data into a plurality of equal rate data sub-streams, storing the equal rate data sub-streams into a sub-server content buffer, splitting buffered data into a plurality of data sub-streams, calculating a plurality of sub-stream rates and pushing the data sub-streams into corresponding transmission queues.
