Abstract:
An apparatus comprising a network element (NE) configured to support routing-associated signal compatibility constraint information that is associated with the NE using Generalized Multi-Protocol Label Switching (GMPLS) and an open shortest path first (OSPF) routing protocol, wherein the signal compatibility constraint information comprises a modulation type list, a Forward Error Correction (FEC) type list, a bit rate range list, and an acceptable client signal list, and wherein the signal compatibility constraint information is associated with a resource block (RB) pool for a plurality of NEs. Also disclosed is a network component comprising a transmitter unit configured to transmit signal compatibility constraints via GMPLS OSPF routing, wherein the signal compatibility constraints comprise a modulation type list, a FEC type list, a bit rate range list, and an acceptable client signal list.
