1. A method of discovery of a set of computer nodes in a computerized network, comprising the steps of: (a) selecting a computer node amongst computer nodes in a group of computer nodes to be processed; and (b) instructing from a source computer node to implement a discovery procedure for the selected computer node via a source routing mechanism based on source routing information of the selected node previously detected, said discovery procedure comprising broadcasting a neighbor discovery request from a computer node currently selected on a shared transmission medium of the network and receiving at the computer node currently selected replies sent by neighbor computer nodes on the shared transmission medium; (c) receiving at the source computer node the selected replies sent by neighbor computer nodes to the computer node currently selected; (d) adding said neighbor computer nodes to the group of computer nodes to be processed; and (e) iteratively changing the selected computer node by repeating steps (a) through (d) for other computer nodes in the group of computer nodes to be processed, until all computer nodes of the set are discovered.
