576  JVK, HH  Efficient resource discovery is an essential problem in peer-to-peer networks because there is

578    approaches in which all modern Peer-to-Peer systems fall: the loosely structured approach
579    and the tightly structured approach. In the loosely structured approach the construction
580    and the maintenance of the network is controlled loosely while tightly structured approach
581    is constructed deterministically, which all participating peers have to follow; the topology of the
582    overlay and the placement of services is controlled tightly. Currently either of the approches
