1. A method 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;

    if network latency has not been measured for at least d+1 peer nodes, estimating the network coordinates of the host node; and

    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.
