Abstract: In a node configured to communicate with one or more other nodes over a network, available bandwidth for network traffic may be distributed among two or more distinct channels of communication within a single application running on the node. An available bandwidth may be detected for communication between the first node and a second node. A distribution may be determined for the available bandwidth among the two or more communication channels. A sending rate may be adjusted for data sent from the first node to the second node over one or more of the two or more communication channels in response to a detected change in the available bandwidth.

Abstract: Network bandwidth detection and distribution and prioritizing network traffic among two or more distinct channels of communication within a single application in a node configured to communicate with one or more other nodes over a network is disclosed. For a particular time quantum, a bandwidth quantum may be distributed amongst two or more communication channels according to priorities associated with those channels.

Abstract: 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.

Abstract: A method and system for load balancing the distribution of a file or block of data to multiple recipients on a peer to peer network is disclosed.

Abstract: In a distributed hash table overlay network, messages directed to a message ID are relayed one or more nodes that have published interest in that message ID. Messages are distributed, processed, and/or cached in accordance with relay policies, which enable a wide variety of different applications. Nodes to specify relay policies on a per-node, per-message, and/or per-message ID basis. Relay policies can specify any behavior associated with messages, including: message caching, distribution, and processing as well as migration of relay policies when nodes join or leave the network. Intermediate nodes can perform any arbitrary processing of message based on relay policies. Intermediate nodes can offload processing to other nodes, either by forwarding messages to a different message ID or by enlisting the help of nodes subscribed to the message ID. Messages can include one or more subfields specifying commands and/or data to be evaluated by the intermediate node.

Abstract: An overlay network uses flexible neighbor selection based on network address translation (NAT) to define routing between nodes. The NAT type is used as a flexible neighbor selection criteria, either alone or in conjunction with other criteria. A method of selecting a neighboring node for a first node in a distributed hash table network includes determining a desired key value for a node finger table entry and requesting a set of candidate neighboring nodes near this desired key value. The method determines a network address translation type of each of the set of candidate neighboring nodes and ranks the set of candidate neighboring nodes accordingly. The method selects one of the set of candidate neighboring nodes based on the ranking. The NAT types of candidate neighboring nodes are determined by sending probe messages or from data received from a central overlay network server.
