Abstract: A peer node coupled to a plurality of other peer nodes in an overlay network may process a broadcast message from an upstream peer node containing a plurality of packets by identifying packet missing from the message, identifying an upstream node to which the peer node has an existing inbound connection and which has the missing packet, and obtaining the missing packet from the upstream node. A message from an upstream node may be processed by buffering a subset of the packets of the message in a buffer for a finite period of time before and after the peer node consumes the packets and by identifying one or more of the buffered packets to one or more finger nodes.

Abstract: The distribution of content over a peer to peer (P2P) network can be improved by utilizing at least one broadcast of the content in order to quickly seed the P2P network. When content is first to be distributed across the network, a broadcast can be scheduled that each peer device with broadcast receiving capability and within range of the broadcast is able to receive. As soon as a peer device receives at least a portion of the broadcast content, that peer can begin redistributing the content across the P2P network. Any errors or missing portions of the received broadcast content can be corrected by requesting a copy of the missing or incorrect portion from another peer on the P2P network.

Abstract: Handling of multiple connections during NAT traversal for a node behind a symmetric NAT is disclosed. The likelihood of connection failure during symmetric NAT traversal may be reduced by serializing critical time windows after port prediction. Once a connection request has been sent for a first connection, port prediction for a subsequent connection may be delayed until a connectivity check has begun for the first connection. This process may be repeated to handle NAT traversal for multiple simultaneous connections to different nodes.
