Abstract

A scalable framework named Dual Routing Engine Architecture in Multi-layer, multi-domain and multi-constraints scenarios (DREAM) is proposed for the routing issue in large-scale dynamic optical networks. DREAM-based optical transport network testbed with 1000 control plane nodes and multi-terabit per second ODUk electrical cross-connects is first experimentally demonstrated. Two proposed routing schemes, i.e. DRE Forward Path Computation (DRE-FPC) and Hierarchical DRE Backward Recursive PCE-based Computation (HDRE-BRPC) are deployed and validated on the testbed, compared with traditional hierarchical routing (HR) scheme. Experimental results show the good performance of DREAM.
