Embodiments of the invention are generally directed to a system and method
of implementing peer model architecture in integrated optical networks.
In one embodiment, heterogeneous domains of nodes share a common control
plane via routing and signaling adjacencies established through a network
layer control channel. For example, in one embodiment, one or more
Internet Protocol (IP) compliant routers, one or more Time Domain
Multiplexing (TDM) switches, and one or more Wave Division Multiplexing
(WDM) optical cross connects (OXC) run a common instance of an Interior
Gateway Protocol (IGP).
