We propose a scalable framework for triple M routing in dynamic optical networks and first experimentally demonstrates a DREAM-based optical transport network with 1000 control plane nodes and multi-terabit per second ODUk electrical cross-connects.
Presented in this paper is a dual routing engine-enabled optical network platform with multi-domains and multi-layers. Structure and key technologies of the platform are outlined. Experiments on it with 2 routing strategies are conducted, the results are discussed and the network scalability is evaluated.
Different routing schemes for multi-layer and multidomain optical networks are analyzed, and a novel routing architecture is described in the paper. Cooperation models between dual routing engine in large-scale multi-layer and multidomain optical networks are researched, and an optimal model is proposed and simulated. Then the scalability of dual routing engine architecture is validated on DRE testbed.
Architecture of DREAMSCAPE is introduced into optical networks combined with ASON/GMPLS, and a selection scheme is proposed for group engine (GE) and unit engine (UE). Then the cooperation relationship of modules in GE and the verification platform are described.
