Optical Network Virtual Mapping Method Based on Network Container

With the rapid development of data center, cloud computing and Internet of things technology, the ossification of traditional optical network architecture is increasingly prominent. Virtual optical network services have the characteristics of business diversification and differentiation, which leads to the increasingly complex virtual mapping between virtual network and elastic optical network. At the same time, the virtual network and the physical network are not completely decoupled. The difference of physical network results in the limited flexibility of virtual network mapping and restricts the rapid deployment of virtual network services. In order to solve this problem, this paper proposes an optical network virtual method based on network container. Firstly, a three-tier architecture model of "virtual network layer, network container layer and physical network layer" is designed, and the network container and its generation rules are defined. Secondly, a virtual network service mapping method based on network container is proposed. Finally, the physical network resources of elastic optical network are virtualized into multiple differentiated network containers to realize the rapid mapping and flexible configuration of virtual network services and network containers.
