Abstract: The routing traffic in wireless networks is performed in accordance with a routing metric. The routing metric can reflect the effects of future self-traffic of a forthcoming communication flow. In a described implementation, a routing decision is made for a forthcoming communication flow that is to propagate over multiple nodes of a multi-hop wireless network. The routing decision is based on at least one predicted effect on the wireless network from self-traffic of the forthcoming communication flow.

Abstract: A peer-to-peer (P2P) probing/network quality of service (QoS) analysis system utilizes a UDP-based probing tool for determining latency, bandwidth, and packet loss ratio between peers in a network. The probing tool enables network QoS probing between peers that connect through a network address translator. The list of peers to probe is provided by a connection server based on prior probe results and an estimate of the network condition. The list includes those peers which are predicted to have the best QoS with the requesting peer. Once the list is obtained, the requesting peer probes the actual QoS to each peer on the list, and returns these results to the connection server. P2P probing in parallel using a modified packet-pair scheme is utilized. If anomalous results are obtained, a hop-by-hop probing scheme is utilized to determine the QoS of each link. In such a scheme, differential destination measurement is utilized.

Abstract: Overlay network peers may be grouped so that each peer in a peer group has a similar transport network proximity measure with respect to the peers in other peer groups. A first set of transport network distances may include distances between a peer group and peer group neighbors of the peer group. A second set of distances may include distances between a peer and the peer group neighbors of the peer group. The peer may decide to join the peer group if the first set of distances is near to the second set. A first peer group may query a second peer group for the second peer group's neighboring peer groups. The distance between the first peer group and each of the second peer group's neighbors may be measured. Overlay network connections may be established between the first peer group and the closest of the second peer group's neighbors.
