<p>A method of determining proximity between a root node and a leaf node in a network is presented. The method comprises computing a link proximity value between any two mutually connected nodes in the network. At an initial node, a proximity computation request message is sent containing a proximity counter to an intermediate node to which the initial node is connected. At an intermediate node, being connected to a first node and to a second node, upon receipt of the proximity computation request message containing a proximity counter from the first node, the computed link is added to a proximity value and passed on the proximity computation request message to the second node. At a final node, upon receipt of the proximity computation request message, the proximity between the root node and the leaf node is determined as the value indicated by the proximity counter.</p> |
