摘要:
A method is provided for a host node in a computer network to determine its coordinates in a d-dimensional network space, comprising discovering an address of a peer node in the network, measuring network latency between the host node and the peer node, determining whether network latency has been measured for at least d+1 peer nodes, where, if network latency has not been measured for at least d+1 peer nodes, estimating the network coordinates of the host node, and where, if network latency has been measured for at least d+1 peer nodes, calculating the network coordinates of the host node using d+1 measured latencies.
