摘      要：With the development of large-scale, multi-region and multi-layer networks,policybased and constraint-based path computation is more and more complicated and dynamic routing becomes one of the key issues in GMPLS/ASON *** combine the advantages of both GMPLS control plane and PCE,novel dual routing engine architecture of multi-layer and multi-region scalable optical networks is proposed in this paper. The collaboration of group engine and unit engine makes it effective to optimize path computation especially under the condition of complex *** functional architecture of dual routing engine is *** potential cooperation relationships between group engine and unit engine are investigated and simulation results for multi-region and multi-layer routing schemes are analyzed.
