That pretty much describes it. Nox uses a very simplistic discovery
method of sending out a unique LLDP packet per connected switch port.
On receipt of an LLDP packet it can then determine the link-state based
on the incoming port and switch that the packet was received on.

Dear all:
Sorry to bother to everyone.
But I am very interested about the NOX Controller can use discovery to
find the complete topology.
But the related sites are not very detailed description of its
process. Anyone can tell me in detail how it is done?
research
http://noxrepo.org/manual/app-index.html#discovery
it only say:
Discovery sends LLDP packets out of every switch interface. It uses
received LLDP packets to detect switch links, at which time it
generates Link_events.

Ian
