Recently, there are expectations for transport networks among wide area to provide paths dynamically applying Software-Defined Networking (SDN) for faster provisioning paths with low latency and high availability. However, transport networks are actually heterogeneous networks consisting of multiple layers and domains unlike data center networks where SDN have been applied. In addition, virtualization of network resources is also expected by applying SDN. We propose a network orchestrator based on ODENOS for orchestrating multi-layer and multi-domain networks and for providing virtual views to users. Proposed network orchestrator has four features. Firstly, a common data model is introduced for solving a problem of differences among layers and domains. Secondly, relations between layers/domains are managed for solving a problem about lack of managing relations between layers/domains. Thirdly, data model and interfaces are converted between the network orchestrator and layer/domain for solving a problem of differences of methods of path setup among layers/domains. Lastly, a virtual view is created for each user with separated topology based on an ID of each user for solving a problem about lack of a method to create separated views for each user. Results of performance evaluations show that the proposed network orchestrator can dynamically provide virtual views to users on demand.
